Ibm Drive Channel Status Test

This test auto-discovers the drive channels on a storage controller, and reports the number and type of errors experienced by each channel.

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 for each drive channel on the storage controller to be 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.
