2. For each drive to be removed, select the box in the Unassigned column to add a
check mark (this removes the check mark in the logical library box).
Note: You cannot move a drive into the Unassigned column if it contains a cartridge.
Also, if the drive to be removed is a control path drive, you must ensure that a second
drive is designated as the control path drive before you remove the first control path
drive.
3. From the Select Action drop-down box, select Apply, then select Go. The Drive
Assignment Operation in Progress screen displays. After a short delay, the Success
screen displays to indicate that the changes are complete.
4. Select Close. The Drive Assignment screen redisplays. The drives that you selected
are checked in the Unassigned column and are no longer available to the logical
libraries.
5. Use the appropriate procedure to physically remove an LTO Ultrium Fibre Channel
drive or a 3592 Fibre Channel drive from the physical library.
6. After you remove the drive from the library, select Drives —> Drive Assignment.
After a short delay, the Drive Assignment screen redisplays.
7. Ensure that the drive does not display in the Drive Assignment screen. If it displays,
wait a few moments and refresh the screen again (some delay in this procedure is
expected).
Note: If you physically remove a drive that is not assigned to a logical library, that
drive will not display in the Drive Assignment screen; if you remove a drive that is
assigned to a logical library, its background in the Drive Assignment screen becomes
gray. This indicates that the drive no longer communicates. The drive remains in its
associated logical library until you unassign it by using the procedure to remove a drive
from a logical library.
