HP StoreEver Ultrium Tape Drives - Manual (Page 11)

message “The device is not ready”. When a formatted LTFS cartridge is loaded into the drive,
the index will be read and checked, and then the volume may again be accessed.
•
Format: Starts the FormatWizard to guide you through the steps and options of creating a
fresh volume on the current cartridge; more information is given in
“Using the FormatWizard”
(page 14) .
•
Unformat: Runs the UnformatWizard to guide you through the steps and options of removing
the LTFS format from the tape.
•
Check: Runs the Error-checking tool which scans the volume for consistency and can correct
certain problems with the format; see
“Using the CheckWizard” (page 17) for more details.
File permissions
The HP StoreOpen Standalone application manages a common set of file permissions for all files
and users; file and directory ownership is not recorded to tape media. The only permission that is
tracked is write-protect information.
File names
To maintain compatibility when copying files between multiple platforms, it is strongly recommended
that do you do not use the following characters LTFS filenames, directory names, or extended
attributes: * ? < > : " | / \
Limitations
•
When the tape cartridge is almost full, further write operations will be prevented. The free
space on the tape (for example, as reported by Explorer) will indicate that there is still some
capacity available, but that is reserved for updating the index when the tape is unmounted.
•
Future mounts of a cartridge that is almost full (that is, it has passed the point at which “early
warning” is reported) will mount as Read Only, to prevent further modifications that may not
fit on the tape. This status is cleared when the cartridge is reformatted (using mkltfs) or when
the volume is rolled back, erasing the history.
•
MAM and LTFS attributes cannot be listed using the ltfsattr command. The ltfs and MAM
attributes are case sensitive.
•
LTFS volume name cannot be modified on a LTFS tape which is full.
•
Disconnecting or powering off a tape drive while it is mounted can make the LTFS volume
inconsistent. Always un-mount the LTFS volume before disconnecting or powering down the
tape drive.
Working with Windows Explorer
Once the mapping has been established and an LTFS-formatted cartridge loaded, you can access
the contents of the cartridge either at a command prompt or through Windows Explorer. The
following screenshot shows an LTFS volume viewed in an Explorer window:
