Overview The Global Spare option lets you remotely replace a failed drive
using a drive that is already installed in the library. Using a Global Spare
allows you to continue your backup operations and replace the failed drive
the next time you are physically present at the library.
Usage Requirements Before you can use the Global Spare option, the
following requirements must be met.
 One or more Global Spare drives must already be configured in the
The drives that are configured as Global Spares must be connected to the same
Important
Fibre Channel arbitrated loop or fabric (SAN) as the drives they replace. If they are
not connected to the SAN, they are not accessible to the application software.
After the Global Spare is activated, you may need to reconfigure your switch to
access the spare drive.
 The failed drive must be idle, with no pending backup or restore
Cartridge Inventory If the failed drive contains a cartridge when it is
replaced by the Global Spare, that cartridge is removed from the partition's
inventory. If you are able to remove the cartridge from the failed drive after
you remove it from the library, reimport the cartridge (see Importing into a
Storage or Cleaning Partition).
PostScan Requirements If a partition is configured to use either FullScan
or QuickScan using Global Spares, keep in mind that the PostScan process
"owns" the Global Spare drive it is using until it processes all of the
cartridges in the PostScan queue for the partition. As a result, a Global
Spare drive that is being used for PostScan is not available for use as a
spare.
If all of the Global Spare drives assigned to the partition are in use by the
MLM PostScan process, you must pause PostScan to make a Global Spare
drive available, as described in Pause the PostScan Process on page 274.

operations. Backups to the other drives in the partition can continue.
Note: You cannot use a Global Spare drive to replace a failed drive
while the library is actively running the Drive Firmware Update
wizard in the partition.
