Ibm Array Status Test

This test reports the current state of the target storage subsystem, and proactively alerts administrators to failures and space inadequacies experienced by the subsystem.

Target of the test : An IBM DS Raid Storage device

Agent deploying the test : A remote agent

Outputs of the test : One set of results the storage array being monitored

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed .

Host

The IP address of the storage device

Port

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

SMCliLocation

The test uses the command-line utility, SMcli.exe, to collect the required statistics from the IBM DS Raid Storage device. To enable the test to run the SMcli.exe, provide the full path to the exe in the SMCliLocation text box.

Note:

If the SMcli.exe resides in say, C:\Program Files\IBM_DS\client, your SMCliLocation should be : C:\Progra~1\IBM_DS\client. On the other hand, if the SMcli.exe resides in say, C:\Program Files (x86)\IBM_DS\client, your SMCliLocation should be: C:\Progra~2\IBM_DS\client.

Alternate Controller IP

By default, the Alternate Controller IP text box is set to none. This implies that by default, the storage device being monitored supports a single controller only, and the IP address of this controller is the same as the IP address of the target Host. Sometimes, a storage device could be configured with two/more controllers, so as to provide fail-over services - in other words, if the primary controller is down, then one of the alternate controllers will take over from the primary to provide the critical storage services. In this case, you can provide a comma-separated list of alternate controller IPs in the Alternate Controller IP text box.

Timeout

Indicate the duration (in seconds) for which this test should wait for a response from the storage device. By default, this is set to 30 seconds.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Storage array status

Indicates the current status of the storage array.

 

The values that this measure can report and the numeric values that correspond to them are listed below:

Note:

This measure reports the Measure Values listed in the table above to indicate the current state of this array. However, in the graph of this measure, the state is indicated using only the Numeric Values listed in the above table.

The detailed diagnosis of this measure will report the logical drives in the array, and the capacity of each drive (in GB).

Total capacity

Indicates the total array capacity.

GB

 

Used capacity

Indicates the total array capacity.

GB

 

Percent free

Indicates the percentage of capacity that is unused.

Percent

Ideally, the value of this measure should be high. A very low value or a value that decreases consistently could be a cause for concern, as it could indicate a steady erosion of space in the array. The lack of storage space is a serious issue that could render the array unavailable for storing any more critical data. You may want to clear space in the array or increase the array capacity.
