v7000 Drive Status Test

A drive that is offline or degraded will be inaccessible to I/O requests, until brought online or the source of the degradation is determined and removed. Using the v7000 Drive Status test, administrators can locate such drives instantly and have the problem fixed before end-users notice.

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 drive of the IBM Storwize v7000 storage system 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 drive.

 

This measure reports the status of this drive as follows:

  • offline
  • online
  • degraded

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

State Numeric Value
offline 0
online 1
degraded 2

Note:

By default, this measure reports the above-mentioned States while indicating the status of this drive. However, the graph of this measure will be represented using the corresponding numeric equivalents of the States as mentioned in the table above.

The detailed diagnosis of this measure if enabled, lists the CURRENT ROLE of this drive, the ENCLOSURE ID and SLOT ID to which this drive is associated, the MEMBER ID of this drive, the MDISK NAME, ERROR SEQ NO and the DRIVE TECHNOLOGY USED.

Capacity

Indicates the current capacity of this drive excluding quorum area.

TB

A quorum disk is a managed disk (MDisk) that contains a reserved area for use exclusively by the system. In the IBM Storwize V7000, internal drives can be considered as quorum candidates. The clustered system uses quorum disks to break a tie when exactly half the nodes in the system remain after a SAN failure.
