Usage Requirements Although a Global Spare drive can be shared by
multiple partitions, assigning a separate Global Spare drive to each
partition is recommended. If you select to perform a FullScan or a
QuickScan using a Global Spare drive, each partition can then perform
PostScan operations whenever the prerequisites are met, without waiting
for PostScan in another partition to complete.
Refer to the following sections for additional information about using the
PreScan and PostScan features:
PreScan and PostScan System Messages Both PreScan and PostScan
generate system messages as possible error conditions are detected (for
example, a broken leader or a media error). The messages indicate that the
error condition was detected by the PreScan or PostScan process and not
during normal operation.
Interaction with Move Requests If a host requests a move while a
cartridge is being scanned using one of the partition drives (PreScan or
QuickScan), the move is delayed until the scan completes and the cartridge
is returned to its slot.
Background Operations To protect you against making changes that could
negatively impact the library’s operation, the BlueScale software
automatically prevents you from performing certain operations while the
library is performing background operations, including Media Auto
Discovery, PreScan, or PostScan.
You cannot import or export cartridges while the library is running a
Media Auto Discovery or PreScan operation, nor can you use the
BlueScale user interface to move cartridges from one location to
another in the library.
If you cannot wait for the operation to complete, you can stop Media
Auto Discovery or PreScan and then manually start it at another time
(see Stop the Discovery Process on page 288).
