v7000 Enclosures Test

Each IBM Storwize V7000 system has one or two (optional) control enclosures that contain node canisters, disk drives, and power supply units. If a control enclosure is not visible to the SAN, then users will not be able to access the storage system. This is why, administrators need to closely monitor the state of each enclosure, and ensure its continuous availability to the SAN. This can be achieved using the v7000 Enclosures test. This test monitors each enclosure and reports its current state and composition, so that administrators can be instantly alerted to the abnormal state of the enclosure.

Target of the test : An IBM Storwize v7000 storage system

Agent deploying the test : A remote agent

Outputs of the test : One set of results for every enclosure being monitored.

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed.

Host

The host for which the test is to be configured.

Port

The port number at which the specified host listens to. By default, this is NULL.

Timeout

Specify the duration (in seconds) beyond which the test will timeout in the Timeout text box. The default value is 60 seconds.

Detailed Diagnosis

To make diagnosis more efficient and accurate, the eG Enterprise suite embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option.

The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:

  • The eG manager license should allow the detailed diagnosis capability
  • Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.
Measurements made by the test
Measurement Description Measurement Unit Interpretation

Status

Indicates the current status of this enclosure.

 

This measure reports any one of the following values:

  • offline
  • online
  • degraded

The numeric values that correspond to the above-mentioned measure values are as follows:

Measure Value Numeric Value Description
offline 0 A managed or unmanaged enclosure is visible
online 1 A managed enclosure is not visible, and other fields hold their last known values
degraded 2 An enclosure is visible, but not down both strands

Note:

By default, this measure reports the above-mentioned Measure Values while indicating the status of the enclosure. However, in the graph of this measure, enclosure state will be represented using the corresponding numeric equivalents only.

The detailed diagnosis of this measure if enabled, lists the type of the enclosure, the managed status of the enclosure, the IO group ID, the IO group name, the machine type and the serial number of the enclosure. This way, you can accurately determine the I/O groups that will be rendered inaccessible if an enclosure goes offline or is degraded.
