Error is 'error'.
Operation will continue. Please manually delete the snapshot after backup is completed.
Explanation
During TSM client operation, it was not possible to delete the snapshot for some reason. However, TSM operation was completed successfully. One of the reasons that the snapshot delete failed maybe due to the fact that AIX JFS2 expects the snapshot delete requests for a given filesystem to be issued in the order of oldest snapshot first, next oldest snapshot second and so on. If there are other processes using older snapshots for the same filesystem, it fails the delete request. Also, TSM only deletes snapshots that was created by one of its processes. It will not delete older snapshots created by other applications or users. In this case, the user will have to manually delete all the older snapshots so that the next TSM command can complete successfully.
System action
Processing continues, and the snapshot delete error is ignored.
User response
Please manually cleanup the snapshots as follows:
Query the snapshot: snapshot -q -c: <source FS>.
Snapshot name will be of the format: tsmxxxxxxxxxx.
Check if it is mounted: df -k | grep tsmxxxxxxxxxx.
Unmount the snapshot: umount -f tsmxxxxxxxxxx.
Remove snapshot mount point: rmdir tsmxxxxxxxxxx.
Delete the snapshot: snapshot -d /dev/tsmxxxxxxxxxx.
If snapshot delete fails with "Device Busy" or some other error, unmount the snapshot source filesystem: umount -f <source FS>.
Retry snapshot delete: snapshot -d /dev/tsmxxxxxxxxxx.
Check if any logical volumes are remaining: ls -l /dev/tsm*.
Remove any remaining logical volumes: rmlv -f tsmxxxxxxxxxx.
Remount source file system, if previously unmounted: mount <source FS>.
