The IbmDsDrChanStsTest reveals the current status of each drive channel on the storage controller, and also alerts administrators to connection failures between any of the drive channels and the controllers A and B.

• The TEST PERIOD list box helps the user to decide how often this test needs to be executed. 

• 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.

• 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.

• In the TIMEOUT text box, specify the maximum duration (in seconds) for which the test should wait for a response from the device. By default, 30 seconds is set as the TIMEOUT period.

• Once the above value is provided, click on the UPDATE button to register the changes made.
