Chapter 9 Running Your Library
Performing Media Operations
Dell PowerVault ML6000 User’s Guide 177
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.
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 default tape drive mode is online.
• You can select only tape drives in partitions to which you have been
given access.
• The Online/Offline buttons toggle between modes.
• Once taken offline, tape drives remain offline until they are turned
online again, or the library is restarted. Restarting the library will
bring all offline tape drives back online.
The paths to open the appropriate screens are as follows:
• From the Web client, select Operations > Drive > Change Mode.
• From the operator panel, select Operations > Change Drive Mode.
For step-by-step procedures, see the library’s online Help. To access the
online Help system, click the Help icon at the top right of the Web client or
operator panel user interface.
Note: If you change the mode of a control path tape drive to offline, a
caution dialog appears asking you to confirm the mode
change. For information on control path tape drives, see
Working With Control Paths on page 86.
