Other usage information

File names

To maintain compatibility when copying files between multiple platforms, it is strongly recommended
that the following characters should not be used in HP StoreOpen Automation for file names,
directory names, or extended attributes: * ? < > : " | / \

File permissions

HP StoreOpen Automation 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. Files or directories that are write-protected will have permission bits set
to 555; write-enabled files and directories have permission set to 777. By default the user and
group information is set to that of the current user; this can be overridden by use of the -o uid
and -o gid options to HP StoreOpen Automation.

File types

HP StoreOpen Automation also does not support creation of special files and will report "Function
not implemented

".

Library maintenance and management tips

Drive maintenance: The library should be unmounted before taking drives offline, or replacing
them. Remount the library when the maintenance has completed.

Partition changes: The library should be unmounted before modifying or removing a partition
used by HP StoreOpen Automation. Any operation which causes the host machine to see a
different number of slots or drives will require the library to be unmounted first, then re-mounted
after maintenance is complete.

Power cycling: Power cycling or resetting the library will require the library be re-mounted.

NOTE:

To reduce risk of data inconsistency or loss, always wait at least 5 minutes after

unmounting the library device before power cycling or resetting the library.

Barcodes: Media in the library must have barcode numbers, and the barcodes must be unique
within that library or partition. To avoid risk of inconsistent or lost data, do not use two or
more tapes with the same barcode.

NOTE:

If you have media without barcodes, please obtain and apply labels before using

them with HP StoreOpen Automation. One way to do this is with the HP LTO-5 Ultrium RW
Bar Code Label Pack (Q2011A), or HP LTO-6 Ultrium RW Bar Code Label Pack (Q2013A).

Exclusive media access: To avoid risk of data inconsistency or loss, do not use the library's
management interfaces or another application to unload a tape drive while the library device
is mounted.
