A tape library system may be turned off while a tape is mounted. In this case, the tape and drive are disabled and are unusable when the tape library system is started.
This state can be confirmed by activating the TSM dsmadmc command and executing the "query volume format=detail" command. If "disabled" is displayed for the access status, the above state is confirmed.
For recovery, execute the following procedure:
Execute dsmadmc (TSM management client command).
Check whether the drive is disabled.
Execute the "query drive" command to check whether the drive is disabled.
If the drive is disabled (and "yes" is not displayed for the online state), execute the following command.
"update drive library-name drive-name online=yes"
Confirm that the drive is enabled.
Execute the "query drive" command to check whether the drive is enabled.
Check the tape status.
Execute the "query volume format=detail" command to check the status.
If the tape is disabled, execute the following command to enable the tape.
"update volume tape-name access=readwrite"
Confirm that the tape is enabled.
Execute the "query volume format=detail" command to check that the tape is enabled.
If the access status has returned to the read/write status, the tape is enabled.
