170 Chapter 5 Troubleshooting
5.3.2.5 Identify the Error Location and Correct Hardware Errors
Use the Windows and hardware management tools to identify the error location, and then
take appropriate, corrective action. If an error occurs in the path, HDLM outputs an error
message to the event log of the host. Information about the path in which the error occurred
is also output to the event log. For hardware maintenance, contact your hardware vendor or
maintenance company if there is a maintenance contract.
5.3.2.6 Place the Path Online
After the path recovers from the error, use the dlnkmgr command's online operation to
place online the path that went offline due to the error. For details on the online
operation, see section
7.5. Execute the following command:
>dlnkmgr online
Executing this command places all the offline paths online. If any path cannot be placed
online due to an error, the KAPL01039-W message appears. To ignore such paths and to
continue processing, type y. Type n to cancel the processing. Check the status of the paths
that cannot be placed online, and take appropriate, corrective action.
Notes:
Even if you execute the dlnkmgr command's online operation (with the -pathid
parameter) for the paths in the Offline(E) status, some paths may not be placed
online. In this case, use the offline operation to change those paths from the
Offline(E) status to the Offline(C) status. Then, execute the online operation.
The system automatically checks whether the target paths are available, puts available
paths into the Online status, and puts unavailable paths into the Offline(E) status.
The paths in the Offline(E) status have not recovered from an error yet. Take
corrective action for the error, and then execute the online operation again.
If path errors occur on all of the paths, and some or all of the paths are recognized by
Windows, disk numbers might then be changed from the ones that were assigned when
the host started. If this happens, restarting the host will cause the disk numbers to be
changed back to the ones that were assigned when the host started. After the disk
numbers have changed back, use Veritas Backup Exec for Windows or the Intelligent
Disaster Recovery functionality of Veritas NetBackup.
