Using directed maintenance procedures

You can use directed maintenance procedures (DMP) to diagnose and resolve problems with the SAN Volume Controller.

For example, to repair a SAN Volume Controller cluster, you might perform the following tasks:

Analyze the error log
Replace failed components
Verify the status of a repaired device
Restore a device to an operational state in the cluster
Mark the error as fixed in the error log

Directed maintenance simplifies these procedures by automating as many of the tasks as possible.

The following procedures and panels show examples of what you might see when you use the DMPs. The specific DMPs and panels that you see depend on the procedure that you select.

Note: The following procedures and graphics are examples of what you might see when you use the DMPs. The DMPs and graphics that you see depend on the procedure that you select. This task assumes that you have already launched the SAN Volume Controller Console.

Our example uses the SAN Volume Controller Console to repair a SAN Volume Controller cluster. Perform the following steps to start the DMP:

Click Start Analysis from the Run Maintenance Procedures panel.
Figure 1. Start Analysis panel

The list might contain any number of errors that must be repaired. If there is more than one error on the list, the error at the top of the list has the highest priority and must always be fixed first. If you do not fix the higher priority errors first, you might not be able to fix the lower priority errors.
Click OK.
From the Error Code column, click on the number of the error code. The panel displays the error code and provides a description of the condition. You can click Continue to go forward or Cancel to return to the previous panel.
One or more panels might be displayed with instructions for you to replace parts or perform other repair activity. If you are not able to complete the actions at this time, click Cancel, which returns you to the previous panel. Click Cancel until you are returned to the Viewing Clusters panel. When you return to the DMPs, the repair can be restarted from step 1. When the actions that you are instructed to perform are complete, click OK. When the last repair action is completed, the DMPs might attempt to restore failed devices to the cluster.
After you complete the fix, you see the statement Click OK to mark the error as fixed. Click OK. This action marks the error as fixed in the error log and prevents this instance of the error from being listed again.
When you see the statement The repair has been completed., click Exit. If other errors need to be fixed, those errors are displayed and the DMPs continue.
If no errors remain, you are shown the following statement: There are no unfixed errors in the error log.
The statement indicates that no further repair procedures are necessary. Verify the repair using MAP 5700: Repair verification.
