The IbmDsLdevStatusTest reports the current status of each logical drive (i.e., LUN), and that of the read and write caches on each drive.

The parameters of this test are as follows:

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

• In the HOST text box, the host name of the storage array for which the test is to be configured has to be specified.

• In the PORT text box, specify the port at which the HOST listens. By default, this is set to NULL.

• 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.

• To make diagnosis more efficient and accurate, the eG Enterprise suite embeds an optional DETAILED DIAGNOSIS 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.

• If multiple components of the same component type are awaiting configuration, then an APPLY TO OTHER COMPONENTS check box will appear in this page. Clicking on this check box will allow you to apply the configuration to all/selected components of that type.

• Finally, click the Update button.

When changing the configuration for specific servers, a “*” beside the text box corresponding to the parameter signifies that these values have to be manually configured by the user. The parameter values that require to be configured will typically be prefixed with a “$” or contain a series of “*”. A value of "none" in the parameter value indicates that the corresponding parameter value can be changed if required.
