HP StoreEver Ultrium Tape Drives - Manual (Page 17)

•
Usage example 2: list available tapes on an un-mounted library, so one can be selected for
checking
ltfsck --device=/dev/sg7
•
Usage example 3: perform full recovery on a specified tape in a mounted library
ltfsck -b DG6359L5
Available options are:
Specify the barcode of the tape to be checked -b, --barcode=
Specify the generation to roll back -g, --generation=
Display full index information (effective only for -l option) -m, --full-index-info
Set traverse mode for listing rollback points. Strategy should be forward
or backward (default=backward) -v, --traverse=
Roll back to the point specified by -g -r, --rollback
Do not roll back. Verify the point specified by -g (default) -n, --no-rollback
Recover extra data blocks into directory_ltfs_lostandfound -f, --full-recovery
Recover EOD missing cartridge.
Some blocks might be erased, but recover to final unmount point with
an index version of at least 2.0.0 or earlier. (Must be used for a
cartridge that cannot be recovered by a normal option.) -z, --deep-recovery
List rollback points -l, --list-rollback-points
Erase history at rollback -j, --erase-history
Keep history at rollback (default) -k, --keep-history
Suppress informational messages -q, --quiet
Enable diagnostic output -a, --trace
This help -h, --help
Full help, including advanced options -p, --advanced-help
Enable full function call tracing (slow) -x, --fulltrace
Capture full index information to the current directory (-g is effective
for this option) --captureindex
NOTE: The -z option should only be necessary when a mount operation has failed and ltfs
has advised that deep recovery is required.
Note also that the "erase history" operation cannot be undone, so this option should be used only
when you are sure that you need it.
