NOTE: When library control path failover is first enabled, the hardware address for the
library will change.
Windows example: Bus Number 0, Target ID 0, LUN 1 becomes Bus Number 0, Target Id 2,
LUN 0
Linux example: /dev/sg3 HP MSL G3 Series 7.41 becomes /dev/sg5 HP MSL G3
Series 7.41
If the library detects a situation when it is necessary to remove the primary master drive or
force a failover, power off the drive from the RMI Configuration: Drive 1 (LUN) screen. This
will disable the drive and pass the library control path to the alternate drive. If the disabled
drive is replaced with a new drive, the library LUN stays with the alternate drive until manually
reassigned back with the RMI Configuration: System > Library LUN hosted by Drive.
Alternative Drive for Library Control Path — If the library is configured for library control path
failover, select the drive number of the alternative drive.

This page shows the current configuration of all drives and allows modification to the configuration.
You can also select Power on through this page. (See Configuration: Drive page (parallel SCSI),
Configuration: Drive page (Fibre Channel), or Configuration: Drive page (SAS)).
