During the termination phase of TSM client operation, it was not possible to unmount the snapshot for some reason. However, TSM operation was completed successfully.
Processing continues, and the unmount error is ignored.
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>.
