v7000 Enclosure Canisters Test

The IBM Storwize V7000 solution consists of one or two control enclosures and, optionally, up to 18 expansion enclosures (and supports the intermixing of the different expansion enclosures). Control enclosures contain two node canisters, and expansion enclosures contain two expansion canisters.

The expansion canister is a hardware unit that includes the serial-attached SCSI (SAS) interface hardware that enables the node hardware to use the drives of the expansion enclosure.

The node canister is a hardware unit that includes the node hardware, fabric and service interfaces, and serial-attached SCSI (SAS) expansion ports.

This test reveals the current status of each canister available in the enclosure of the IBM Storwize v7000 storage system, so that defective canisters can be promptly isolated and issues fixed.

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 each canister being monitored.

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed.


The host for which the test is to be configured.


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


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 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


Indicates the current status of this canister.


This measure can report any 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 The canister could not be detected.
online 1 The canister is present and working normally.
degraded 2 The canister is present but not working normally.


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

The detailed diagnosis of this measure if enabled, lists the type of the canister, the node ID and the name of the node to which the canister is attached.
