Taking a Tape Drive Online or Offline

Taking a Tape Drive Online or Offline
172
There are two tape drive modes: online and offline.
• Online — Tape drive is available for use. This is the normal operating
mode for the tape drive.
• Offline — Tape drive is offline to the host application and is not
available for cartridge load and unload (move) operations initiated
by the host application, but it remains available for Web client or
operator panel initiated move commands.
Note: If a cartridge is already in the tape drive when you take the
tape drive offline, then the host can still read and write
data on the tape.
Some operations require that the tape drive be offline. You can take a
tape drive offline rather than the entire library or partition so as to
minimize disruption of library operations. A drive taken offline will
remain offline until you bring it back online, or until the library is
rebooted.This topic focuses on using the library user interface, not the
host application, to change the tape drive mode. Using the library to
change tape drive mode may affect the host application. See your host
application documentation for more information.
Details on changing the tape drive mode include:
• The online/offline state follows the tape drive slot, not the particular
tape drive (if the tape drive were to be moved to a different slot in
the library).
• You can select only tape drives in partitions to which you have been
given access.
• If you change the mode of a control path tape drive to offline, a
caution dialog displays asking you to confirm the mode change. For
information on control path tape drives, see
Paths on page 67.
You can change the tape drive mode from both the operator panel and
the Web client.
