Assign Global Spare Drives
The Global Spare option lets you remotely substitute a working drive for a
failed one using a spare drive in the library. Having a Global Spare drive in
the library lets you continue your backup operations and replace the failed
drive the next time you are physically present at the library. See Using a
Global Spare Drive on page 402 for instructions on how to use the Global
Spare drive in place of a failed drive.
Requirements Before you can configure the Global Spare option, the
following requirements must be met:
The partition must use direct-attached Fibre Channel LTO or TS11xx
technology drives. The Global Spare feature is not available for use
with other drive technologies.
In addition to the drives assigned to the partition for use by the host
software, the library must have direct-attached Fibre Channel drives
available for use as spares in the partition.
All of the drives in a partition with a Global Spare must match the
technology and generation of the Global Spare.
The drives that are configured as Global Spares must be connected to the
same Fibre Channel arbitrated loop or fabric as the drives they would
replace. You may need to reconfigure your switch to access the Global
Spare drive.
Partition Requirements When configuring the partition, keep the
following in mind:
The type of drive you select as the Global Spare determines the type of
drives that you can assign to the partition.
The library prevents you from selecting drives that cannot be used as
Global Spares, including drives already selected as controllers.
Although a Global Spare drive can be shared by multiple partitions, the
drive can only be used by one partition at a time. To ensure that each
partition has access to a Global Spare when needed, configure one or
more dedicated Global Spare drives for each partition.
If you do not currently have a drive that can be used as a Global Spare
installed in the library, but install one later, you can edit the partition to
configure Global Spares.
PostScan Requirements If you plan to use one of the MLM PostScan
features that requires a Global Spare drive, you must configure at least one
Global Spare drive for the partition.
