◦
The library must have two or more LTO-5 or later generation Fibre Channel drives of
the same type (e.g. LTO-generation and form factor).
◦
If the library is partitioned into multiple logical libraries, each logical library must contain
at least two LTO-5 or later generation Fibre Channel drives.
◦
A host connection via a SAN switch with NPIV is enabled for associated ports.
◦
All drive ports are configured as Fabric.
NOTE:
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.

are listed. The default is Automatic.
Port Type — Automatic, Fabric (N), or Loop (NL). Direct connected devices are typically
Loop. Devices connected to a switch are typically Fabric. The default is Automatic.
