Overview VMware

vCenter Operations Manager is a software product that collects performance

and capacity data from monitored software and hardware resources. It provides users with realtime information about potential problems in the enterprise.

vCenter Operations Manager presents data and analysis in several ways:

u Through alerts that warn of potential or occurring problems.

u In configurable dashboards and predefined pages that show commonly needed information.

u In predefined reports.

EMC

Storage Analytics links vCenter Operations Manager with an EMC Adapter. The adapter is bundled with a connector that enables vCenter Operations Manager to collect performance metrics. The adapter is installed with the vCenter Operations Manager user interface.

The connector types are shown in Figure 1 on page 10.

EMC Storage Analytics leverages the power of existing vCenter features to aggregate data from multiple sources and process the data with proprietary analytic algorithms.

adapter A vCenter Operations Manager component that collects performance metrics from an external source like a vCenter or storage system. Third-party adapters such as the EMC Adapter are installed on the vCenter Operations Manager server to enable creation of adapter instances within vCenter Operations Manager.

adapter instance A specific external source of performance metrics, such as a specific storage system. An adapter instance resource is an instance of an adapter that has a one-to-one relationship with an external source of data, such as a VNX storage system.

dashboard A tab on the home page of the vCenter Operations Manager GUI. vCenter Operations Manager ships with default dashboards. Dashboards are also fully customizable by the end user.

health rating An overview of the current state of any resource, from an individual operation to an entire enterprise. vCenter Operations Manager checks internal metrics for the resource and uses its proprietary analytics formulas to calculate an overall health score on a scale of 0 to 100.

metric A category of data collected for a resource. For example, the number of read operations per second is one of the metrics collected for each LUN resource.

resource Any entity in your environment for which vCenter Operations Manager can collect data. For example, LUN 27 is a resource.

resource kind A general type of a resource, such as LUN or DISK. The resource kind dictates the type of metrics collected.

Installation overview EMC Storage Analytics 2.1 consists of two installation packages.

The two packages are:

u vCenter Operations Manager for EMC Storage

u EMC Adapter

vCenter Operations Manager for EMC Storage is a storage only version of vCenter Operations Manager 5.8 developed specifically for EMC storage customers. Installation instructions are in the vCenter Operations Manager vApp Deployment and Configuration Guide at http://www.vmware.com/support/pubs/vcops-pubs.html.

Licensing depends on which version of the vCenter Operations Manager you have installed: u VMware issues the license for vCenter Operations Manager Advanced and Enterprise

versions.

u EMC issues the license for vCenter Operations Manager for EMC Storage.

NOTICE

If you have vCenter Operations Manager Advanced or Enterprise versions with a VMware- issued license, do not install the EMC-issued license for vCenter Operations Manager; installing the EMC-issued license restricts vCenter Operations Manager to storage-only mode.

A 90-day trial license is available with EMC Storage Analytics 2.1 for all supported products. The 90-day trial license provides the same features as a permanent license, but after 90 days of usage, the adapter stops collecting data. You can add a permanent license at any time.

The EMC Adapter collects metrics from resources. It supports vCenter Operations Manager for EMC Storage and the VMware vCenter Operations Manager Advanced and Enterprise versions. EMC Adapter 2.1 supports vCenter Operations Manager versions 5.7.1 and higher.

The adapter installation includes: u Installing the adapter and dashboards.

u Configuring the adapter instances with licensing.

Installing the EMC Adapter and dashboards on page 20 provides installation instructions. The adapter is licensed when Adding EMC Adapter instances for your storage system on page 24 or Editing EMC Adapter instances for your storage system on page 27.

Table 1 on page 15 lists the installation and upgrade options for different vCenter Operations Manager and the EMC Adapter combinations. To perform an installation or upgrade, refer to the instructions for the task that matches your objective.

VNX Block systems The EMC Adapter uses naviseccli to collect metrics from VNX Block systems. It is bundled into the EMC Adapter install file and is automatically installed along with the adapter. Storage processors require IP addresses that are reachable from the vCenter Operations Manager server. Bidirectional traffic for this connection flows through port 443 (HTTPS). Statistics logging must be enabled on each storage processor (SP) for metric collection (System > System Properties > Statistics Logging in Unisphere).

VNX File systems CLI commands issued on the Control Station direct the EMC Adapter to collect metrics from VNX File systems. The Control Station requires an IP address that is reachable from the vCenter Operations Manager server. Bidirectional ethernet traffic flows through port 22 using Secure Shell (SSH). If you are using the EMC VNX nas_stig script for security (/nas/tools/nas_stig), do not use root in password credentials. Setting nas_stig to ON limits direct access for root accounts, preventing the adapter instance from collecting metrics for VNX File.

SMI-S Provider for VMAX requirements The EMC SMI-S Provider for VMAX must be on the network and accessible through port 5988 (non-secure port) or port 5989 (secure port) for communication. If the SMI- S Provider is also used for vSphere vStorage API for Storage Awareness (VASA), follow the recommendations in the SMI-S Provider Release Notes to increase the number of available connections. The user configured in the EMC Adapter instance and connecting to the SMI-S instance must have the role of monitor or administrator.

User accounts To create an EMC Adapter instance for a storage array, you must have a user account that allows you to connect to the storage array or SMI-S Provider. For example, to add an EMC Adapter for a VNX array, use a global account with operator or administrator role (a local account will not work).

To create an EMC Adapter instance for vCenter (where Adapter Kind = EMC Adapter and Connection Type = VMware vSphere), you must have an account that allows you access to vCenter and the objects it monitors. In this case, vCenter enforces access credentials (not the EMC Adapter). To create an EMC Adapter instance for vCenter, use, at minimum, an account assigned to the Read-Only role at the root of vCenter, and enable propagation of permissions to descendant objects. Depending on the size of the vCenter, wait approximately 30 seconds before testing the EMC Adapter. More information on user accounts and access rights is available in the vSphere API/SDK Documentation available at: http://pubs.vmware.com/vsphere-51/ index.jsp?topic=%2Fcom.vmware.wssdk.pg.doc%2FPG_Authenticate_Authorize. 8.3.html.

DNS configuration To use the EMC Adapter, the vCenter Operations Manager vApp requires network connectivity to the storage systems to be monitored. DNS must be correctly configured on the vCenter Operations Manager server to enable hostname resolution by the EMC Adapter.

Time zone and synchronization settings Ensure time synchronization for all EMC Storage Analytics resources by using Network Time Protocol (NTP). Also, set correct time zones for EMC Storage Analytics resources (including the SMI-S Provider if using an adapter for VMAX) and related systems. Failure to observe these practices may affect the collection of performance metrics and topology updates.

Installation and licensing

20 EMC Storage Analytics 2.1 Installation and User Guide

Adapter instances The vCenter Operations Manager requires an adapter instance for each resource to be monitored. The instance specifies the type of adapter to use and the information needed to identify and access the resource.

With EMC Storage Analytics, the vCenter Operations Manager uses EMC Adapter instances to identify and access the resources, such as:

u Adapter instance for vCenter

u Adapter instance for the VNX File

u Adapter instance for the VNX Block

u Adapter instance for VMAX

The adapter instance for vCenter is a prerequisite for other adapter instances. If this adapter is not configured, other adapter instances will function normally but will not display visible connections between the VMware objects and the array objects.

Note

After adapter instances are created, the vCenter Operations Manager Collector requires several minutes to collect statistics, depending on the size of the storage array configuration. Large configurations can take up to 45 minutes to collect metrics and resources and update dashboards. This is a one-time event; future statistical collections run quickly.

Adding an EMC Adapter instance for vCenter For users to traverse health trees from the virtual environment into the storage environment, EMC Storage Analytics requires you to install an EMC Adapter instance for vCenter. All storage system adapter instances require the EMC Adapter instance for vCenter, which you must add first.

To add an EMC Adapter instance for vCenter:

EMC Storage Analytics Dashboards 29

Topology mapping Topology mapping is viewed and traversed graphically using vCenter Operations Manager health trees. The dashboards developed for EMC Storage Analytics utilize topology mapping to display resources and metrics.

EMC Storage Analytics establishes mappings between:

u Storage system components

u Storage system objects and vCenter objects

Topology mapping enables health scores and alerts from storage system components, such as storage processors and disks, to appear on affected vCenter objects, such as LUNs, datastores, and VMs. Topology mapping between storage system objects and vCenter objects uses a vCenter adapter instance.

EMC Storage Analytics Dashboards

40 EMC Storage Analytics 2.1 Installation and User Guide

Pool capacity This has four modes: RAID Group Available Capacity, Storage Pool Capacity Utilization, Storage Pool Available Capacity, and File Pool Available Capacity. In Capacity Utilization mode, the color of the heat map entries shows the value of the % full metric for all non-RAID Group storage pools: u Green indicates 0% full.

u Red indicates 100% full.

In Available Capacity mode, the color of the heap map entries shows the value of the Available Capacity (GB) metric: u Green indicates the largest available capacity on any storage pool for any of the

configured adapter instances.

u Red indicates 0 GB available.

LUN and file system performance This has several modes. In LUN Utilization mode, the color of the heat map entries show the % busy metric for all LUNs grouped by adapter instance: u Green indicates 0% busy.

u Red indicates 100% busy.

In RAID Group LUN Latency mode, the color of the heat map entries shows the value of the Latency (ms) metric: u Green indicates 0 ms latency.

VMAX Overview dashboard This collection of heat maps provides a single view of the performance and capacity for all VMAX resources with configured adapter instances. Heat maps on this dashboard group the contents by adapter instance.

Figure 8 VMAX Overview

The VMAX Overview dashboard displays the following heat maps. For each heat map and selected metric, the configured VMAX Adapter is shown:

Thin Pool Usage This heat map displays the Percent Allocated metric. Percent Allocated displays the allocated capacity in each thin pool. The color of the heat map entries ranges from green to red and corresponds to the percent allocated as follows: u Green indicates that 0% of the thin pool is allocated.

u Yellow indicates that 50% of the thin pool is allocated.

u Red indicates that 100% of the thin pool is allocated.

Storage Group This has four modes: Total Reads (IO/s), Total Writes (IO/s), Read Latency (ms), and Write Latency (ms). Total Reads and Writes represent the aggregate reads or writes for all LUNs in the storage group. Write and Read Latency is the average write or read latency of all LUNs in the storage group.

For Total Reads and Writes, the color of the heat map entries shows the relative number of total reads or writes across all the storage groups. The color ranges from light blue to dark blue. Dark blue indicates the storage group(s) with the highest number of total reads or writes while light blue indicates the lowest. Because the range of values for total reads or writes has no lower or upper limits, the numerical difference between light and dark blue may be very small.

For Write and Read Latency, the color of the heat map entries is based on a scale of latency from 0 to 40ms. This scale is a based on average customer requirements and may not represent a customer's particular requirements for latency. In such cases,

EMC Storage Analytics Dashboards

42 EMC Storage Analytics 2.1 Installation and User Guide

EMC recommends adjusting the scale appropriately. The color of the heat map entries ranges from green to red as follows:

u Green indicates a latency of 0ms.

u Yellow indicates a latency of 20ms.

u Red indicates a latency of 40ms.

LUN Performance This has four modes: Reads (IO/s), Writes (IO/s), Read Latency (ms), and Write Latency (ms). Reads and Writes represent the total reads or writes for a particular LUN. Read and Write Latency is the average read or write latency of all LUNs in the storage group.

For Reads and Writes the color of the heat map entries shows the relative number of reads or writes across all the LUNs. The color ranges from light blue to dark blue. Dark blue indicates the LUN(s) with the highest number of reads or writes while light blue indicates the lowest. Because the range of values for reads or writes has no lower or upper limits, the numerical difference between light and dark blue may be very small.

For Read and Write Latency the color of the heat map entries ranges from green to red and is based on a scale of latency from 0 to 40ms. This scale is a based on average customer requirements and may not represent a customer's particular requirements for latency. In such cases EMC recommends adjusting the scale appropriately. The color of the heat map entries range from green to red as follows:

u Green indicates a latency of 0ms.

u Yellow indicates a latency of 20ms.

u Red indicates a latency of 40ms.

Front End Director This has two modes: Total Bandwidth (MB/s) and Total Operations (IO/s). Total Bandwidth is the cumulative amount of data transferred over all ports of the front-end director. Total Operations is the total number of operations taking place over all ports of a front-end director.

The color of the heat map entries is the same for both metrics. It shows the relative total bandwidth or relative total number of operations, depending on the selected metric. The color ranges from light blue to dark blue. Dark blue indicates the front- end director(s) with the highest number of total operations or the greatest total bandwidth, depending on the selected metric. Light blue indicates the lowest number of operations or the least total bandwidth. Because the range of values for operations or bandwidth has no lower or upper limits, the numerical difference between light and dark blue may be very small.

SRDF Director This has two modes: Total Bandwidth (MB/s) and Total Writes (IO/s). Total Bandwidth is the cumulative amount of data transferred over an SRDF director. Total Writes is the total number of writes over an SRDF director.

The color of the heat map entries is the same for both metrics. It shows the relative total bandwidth or relative total number of writes, depending on the selected metric. The color ranges from light blue to dark blue. Dark blue indicates the SRDF director(s) with the highest number of total writes or the greatest total bandwidth, depending on the selected metric. Light blue indicates the lowest number of writes or the least total bandwidth. Because the range of values for bandwidth or writes

EMC Storage Analytics Dashboards

VMAX Overview dashboard 43

has no lower or upper limits, the numerical difference between light and dark blue may be very small.

SRDF Groups This has four modes: Devices in Session (count), Average Cycle Time (ms), Writes (IO/s), and Writes (MB/s). Devices in Session represents the number of devices in an SRDF session in the SRDF group. The Average Cycle Time is an SRDF/A metric that provides the average elapsed time between data transfer cycles. Writes (IO/s) represents the number of writes per second on the devices in the SRDF group. Writes (MB/s) represents the number of megabytes per second sent from the SRDF group.

The color of the heat map entries is the same for all metrics. It shows the relative devices in session, average cycle time, total bandwidth, or the relative number of writes, depending on the selected metric. The color ranges from light blue to dark blue. Dark blue indicates the SRDF group(s) with the highest number of one these metrics and light blue indicates the lowest number of one of these metrics. Because the range of values has no lower or upper limits, the numerical difference between light and dark blue may be very small.

Topology dashboards The topology dashboards provide an entry point for viewing resources and relationships between storage and virtual infrastructure objects for VNX and VMAX adapter instances.

Troubleshooting 73

Launching Unisphere EMC Storage Analytics provides metrics that enable you to assess the health of monitored resources. If the metrics for VNX Block or VNX File resources indicate that you need to troubleshoot those resources, EMC Storage Analytics provides a way to launch Unisphere on the VNX array in context. Select the resource and click the launch icon as shown in the example in Figure 17 on page 74. The launch icon is available on most widgets.

Note

This feature requires a fresh installation of the EMC Adapter (not an upgrade) and vCenter Operations Manager 5.7.1 or later. You must select the VNX Block or VNX File object to launch Unisphere. There is no Unisphere launch capability for VMAX objects.

Figure 17 Example of launching to Unisphere

Installation logs This topic lists the log files to which errors in the EMC Storage Analytics installation are written.

Errors in the EMC Storage Analytics installation are written to log files in the following directory on the UI VM of the vCenter Operations Manager:

/var/log/emc Log files in this directory follow the naming convention: install-2012-12-11-10:54:19.log.

Use a text editor to view the installation log files.

Troubleshooting

74 EMC Storage Analytics 2.1 Installation and User Guide

Error handling and event logging Errors in the EMC Storage Analytics operation are written to log files on the Analytics VM of the vCenter Operations Manager.

Error logs are available in the /data/vcops/log directory. This directory contains the vCenter Operations Manager logs.

Adapter logs (including adapters other than the EMC Adapter) are in /data/ vcops/log/adapters.

Logs for each EMC Adapter instance are in folders under /data/vcops/log/ adapters/EmcAdapter. For example, if you have five EMC Adapter instances, a directory appears for each of them.

Log files in this directory follow this naming convention: VNX_File-131.log.9.

The log filename begins with the name of the EMC Adapter instance (for example, VNX_Block or EmcAdapter). Filenames beginning with EmcAdapter are common to all connectors. The number that follows the EMC Adapter instance name is the adapter instance ID, which corresponds to a VMware internal ID. The last number in the filename indicates the roll-over increment; the lowest number represents the most recent log. Each roll-over is 10 MB, and ten roll-overs are possible.

View logs relating to EMC Storage Analytics operation in the vCenter Operations Manager GUI. Create and download a support bundle used for troubleshooting.

Viewing error logs EMC Storage Analytics enables you to view error log files for each adapter instance.

Procedure

1. Start the vCenter Operations Manager custom user interface and log in as administrator.

For example in a web browser, type: http:// /vcops- custom

2. Select Admin > Support. Select the Logs tab.

3. Expand the vCenter Operations Collector. Select vCenter Operations Collector > adapters >

Editing the Collection Interval for a resource From the vCenter Operations Manager UI, you can edit the Collection Interval for a resource.

The interval time is 5 minutes by default. Changing this time will affect the frequency of collection times for the VNX Block and VNX File metrics, but the EMC Adapter will only recognize the change if the resource is the EMC Adapter instance. This is normal vCenter Operations Manager behavior.

Instructions on configuring Resource Management settings are provided in the vCenter Operations Manager online help.

Troubleshooting

78 EMC Storage Analytics 2.1 Installation and User Guide

Frequently Asked Questions - General How does a trial license work? A 90-day trial license is provided for each platform that EMC Storage Analytics supports (for example, NS960). The 90-day trial license provides the same features as a permanent license, but after 90 days, the adapter stops collecting data. You can add a permanent license at any time during or after the trial period.

How do health scores work? Health scores measure how normal a resource is acting and grades it on a scale of 0-100. A health score of 100 indicates normal behavior while a lower health score indicates that the resource is acting abnormally. The resource may not be in an unhealthy state but there is an abnormality. Health scores are calculated by a proprietary algorithm which account for several factors including thresholds and historical statistics. vCenter Operations Manager may take up to 30 days to gather enough information to determine what is considered normal in your environment. Until then, you may not see any changes in your health scores.

How many arrays can I add? It is difficult to arrive the exact number of arrays you can add because the scale limits depend on the number of monitored objects and the metrics applied to them. When you deploy vCenter Operations Manager 5.8 and EMC Storage Analytics 2.1 in full profile mode, it can support up to 15,000 objects and up to 5 million metrics. Examples of objects are File Systems, NFS Exports, LUNs, Storage Pools, and Disks. For more details, refer to vCenter Operations Manager 5.8 Release Notes at http://www.vmware.com/ support/vcops/doc/vcops-571-vapp-release-notes.html.

I deleted a resource. Why does it still appear in the vCenter Operations Manager? vCenter Operations Manager will not delete any resources automatically because it retains historical statistics and topology information that may be important to the user. To remove the resource, delete it on the Environment Overview page.

What does the blue question mark in the health score indicate? The blue question mark indicates that vCenter Operations Manager was unable to poll that resource. It will retry during the next polling interval.

What does it mean when a resource has a health score of 0? This indicates that the resource is either down or not available.

Why are my EMC Adapter instances marked down after upgrading to the latest version of the EMC Adapter? EMC Adapter instances require a license to operate. Edit your EMC Adapter instances to add license keys obtained from EMC. Select Environment Overview > Configuration > Adapter Instances.

I have added license keys for EMC Adapter instances. Why are my resources still marked down? License keys are specific to the model for which the license was purchased. Verify that you are using the correct license key for the adapter instance. You can also click the Test button to test the configuration after editing adapter instances.

I have multiple EMC Adapter instances for my storage systems, and I have added license keys for each of them. Why are they still marked down? After adding a license, click the Test button to test the configuration and validate the license key. If you saved the configuration without performing a test and the license is invalid, the adapter instance will be marked down. To verify that a valid license exists, select Environment Overview. The list that appears shows the license status.

Troubleshooting

Frequently Asked Questions - General 79

Figure 19 Status shows: Resource down

What is the difference between vCenter Operations Manager 5.8 from VMware and vCenter Operations Manager included with EMC Storage Analytics? vCenter Operations Manager included with EMC Storage Analytics is based on vCenter Operations Manager 5.8 (Advanced edition) from VMware. However, EMC Storage Analytics is restricted to storage view. For vCenter resources such as virtual machines, you can only see storage or disk related metrics.

How is the detailed view of vCenter resources affected in EMC Storage Analytics? Any changes in the disk system affects the health of vCenter resources such as virtual machines, but EMC Storage Analytics does not show changes in other subsystems. Metrics for other subsystems will either show No Data or ?.

Frequently Asked Questions for VNX

Which VNX arrays does EMC Storage Analytics support? It supports first- and second-generation VNX platforms. Support for CX4 covers CX4-120, CX4-240, CX4-480, and CX4-960 platforms. Supported NS series includes NS120, NS240, and NS960 platforms. A complete list of the supported models in each of these series is available in Installation requirements on page 16.

Will EMC Storage Analytics continue to collect VNX statistics if the primary SP or CS goes down? Storage Analytics will continue to collect statistics through the secondary Storage Processor if the primary Storage Processor goes down. EMC Storage Analytics will automatically collect metrics from the secondary Control Station in the event of a Control Station failover. Note that the credentials on the secondary Control Station must match the credentials on the primary Control Station

Does the Unisphere Analyzer for VNX need to be running to collect metrics? No. VNX Block metrics are gathered through naviseccli commands and VNX File metrics are gathered through CLI commands. However, statistics logging must be enabled on each storage processor (SP) on VNX Block, and statistics logging will have a performance impact on the array. No additional services are required for VNX File.

How does the FAST Cache heatmap work? The FAST Cache heatmaps are based on the FAST Cache read and write hit ratios. This heatmap will turn red if these ratios are low because that indicates that FAST Cache is not being utilized efficiently. These heatmaps will turn green when FAST Cache is servicing a high percentage of I/O.

I purchased a license for the model of the VNX array that I plan to monitor. When I configure the adapter instance for VNX File, why does an "invalid license" error message appear? Control Station may not be reporting the correct model or the array. Log into Control Station and check the array model with the command: /nas/sbin/model. Verify that the array model returned matches the model on the Right to Use certificate.

After a Control Station failover, why is the VNX File adapter instance marked down and why does metric collection stop? The failover may have been successful, but the new Control Station may not be reporting the correct model of the array. This results in a failure to validate the license and all data collection stops. Log into Control Station and check the array model with the command: /nas/sbin/model. If the model returned does not match the actual model of the array, Primus case emc261291 in the EMC Knowledgebase provides possible solutions.

The disk utilization metric is not visible for my VNX Block array. Why not? The disk utilization metric is not supported on VNX arrays running a VNX Block OE earlier than Release 32. Upgrade to VNX Block OE Release 32 or later to see this metric in vCenter Operations Manager.

I am unable to successfully configure an EMC Adapter instance for VNX File when using a user with read-only privileges. Why does this happen? A user with administrative privileges is required while configuring an EMC Adapter instance for VNX File arrays running an OE earlier than 7.1.56.2. Upgrade to VNX File OE 7.1.56.2 or later to be able to configure an adapter instance using a user with read-only privileges.

Frequently Asked Questions for VMAX

I deleted a VMAX adapter, but all the dependent objects still remain in vCenter Operations Manager. Why? Deleting a VMAX adapter instance does not remove its dependent objects. The objects enter an unknown state (blue) but retain their historical metrics. If desired, delete the objects from the Environment Overview page.

If I test a VMAX connection and it fails, how do I know which field is wrong? Unfortunately, the only field that produces a unique message when it is wrong is the license number field. If any other field is wrong, the user is informed the connection was not successful. To resolve the issue, verify all the other fields are correct. Remove any white spaces after the end of the values.

Why is my VMAX array showing as red rather than blue (unknown) just after adding it? If the array is red, the SMI-S may be down or there may be an incorrect parameter in the adapter configuration. Return to the adapter instance configuration and test the configured instance. If it fails, verify all fields are correct. Determine if the SMI-S server is running and can recognize the VMAX array that you are configuring.

All my configured VMAX adapter instances changed to red. Why? This usually happens when the SMI-S Provider is unavailable or there is a clock synchronization problem. This might be network-related or application-related. The SMI-S Provider may have reached the connection limit if the network IP is available. Look for errors in the cimom.log file on the SMI-S box similar to:

26-Mar-2013 05:47:59.817 -900-E- WebServer: The webserver hits its connection limit, closing connection.

Follow the steps in the SMI-S Provider Release Notes to increase the count.

A message next to the array will indicate a clock synchronization problem if a problem exists.

Can I modify or delete the VMAX Overview (or another) dashboard? Yes, the environment can be customized to suit the needs of the user. Rename the dashboard so that it is not overwritten during an upgrade.

I received the following error when I attempted to modify the VNX Overview dashboard although I have only VMAX arrays:

Is this a problem? No, this is a generic error that VMware produces when you attempt to modify a component you do not have.

Why do some of the boxes appear white in the VMAX Overview dashboard? While the metrics are being gathered for an adapter instance, some of the heat maps in the dashboard may be white. This is normal. Another reason the boxes may appear white is that the adapter itself or an individual resource (e.g. a VMAX device) has been deleted, but the resources remain until they are removed from the Environment Overview page.
