of a “removed” condition. A drive slot which does not contain a drive, and has a
position between used slots, needs to be reported as a SCSI element. To signal the
host application that this slot is not usable, its ACCESS bit will be disabled.
Note: When reducing the number of drives in your library, update the Logical
Library configuration. This will remove the Attention LED on the front
panel and the exclamation mark on the Home screen indicating that a drive
is missing.
Updating the Logical Library configuration will also update the drive element
addressing and drive numbering. Replacing LTO half high drives with full high
drives may require you to execute Restore Factory Defaults to correctly update the
drive element addressing and drive numbering. See “Configure Library:
Save/Restore” on page 5-68.
