IBM Tivoli Storage Manager, Version 7.1

Troubleshooting the PowerHA clustered environment

Review the following list for information about troubleshooting common problems. The information that is provided for IBM® PowerHA® SystemMirror for AIX® does not represent all possible scenarios.

Warning messages that are issued after you run the clverify utility

You can run the PowerHA cluster verification utility, clverify, on one node to verify the cluster configuration and the assignment on the PowerHA resources. If you run the clverify utility after you define the Tivoli® Storage Manager server as a PowerHA application, warning messages are issued.

Warning messages display because the shell scripts that start and stop the Tivoli Storage Manager servers are in a shared file system. The shell scripts can only be run on one node at a time. Therefore, the shell scripts can be available on only one node at a time. You can ignore the clverify utility warning messages. If a shared file system cannot be mounted, the Tivoli Storage Manager server cannot be started.

Tivoli Storage Manager server fails to start after you issue the startserver script

If you use the startserver shell script and PowerHA fails to start the Tivoli Storage Manager server, start it manually on a terminal without the quiet option. If you want to run the server with the quiet option, issue the dsmserv -q command.

Messages that are associated with the tctl command

If you issue the tctl -f/dev/rmt2 rewind command the following message might be displayed:

/dev/rmt2: A device is already mounted or cannot be unmounted

This message means that the I/O device is locked with a SCSI RESERVE by a system other than the one on which the tctl command was run. If you are using persistent reservation, the Tivoli Storage Manager server preempts a drive reservation by default. If the device driver does not use persistent reservation, the server performs a target reset.

"ANS4329S Server out of data storage space" message

If the ANS4329S Server out of data storage space message is displayed on a Tivoli Storage Manager client, the license for the Tivoli Storage Manager server might be non-compliant. Issue the QUERY LICENSE command to display the compliance information for the license. If the compliance state is valid, use the QUERY ACTLOG command on the server and review the messages that are displayed to identify the problem.
