QuickScan using a
Global Spare
August 2019
Uses...
One of the drives in the partition. QuickScan verifies all of the data on a single
wrap, from the beginning of the tape (BOT) to the end of the wrap or the end of
recorded data (EOD), whichever comes first.
Notes:
 If a Global Spare drive is not assigned to the partition, a QuickScan using one
of the partition's drives is the only option available.
 If possible, the library avoids using the drive in which the cartridge was most
recently unloaded to perform the QuickScan.
 A QuickScan using a partition's drive is limited to three minutes. If the
QuickScan exceeds this time limit, the operation is aborted and the cartridge
is returned to its slot. The library posts a message stating that the QuickScan
failed. Use FullScan to verify the cartridge.
 While QuickScan is running, all moves in the partition are delayed until the
scan is complete.
A Global Spare drive. QuickScan verifies all of the data on a single wrap, from
the beginning of the tape (BOT) to the end of the wrap or the end of recorded
data (EOD), whichever comes first.
Notes:
 A Global Spare drive must be assigned to the partition.
 Partitions using SAS drives cannot use QuickScan using a Global Spare drive.
 The cartridge does not appear on the BlueScale inventory screens while it is
being scanned. If the cartridge is requested by the storage management
software it is immediately ejected from the drive that is performing the
verification and moved to the location requested by the storage management
software. A system message is posted to indicate that the QuickScan
operation was interrupted. The cartridge is returned to the top of the
PostScan queue and is the first one processed after it is returned to its slot.
 The Global Spare drive cannot be activated while a QuickScan using Global
Spares is running. You must first pause the PostScan process (see Pause the
PostScan Process on page 274). The library immediately aborts the QuickScan
currently in progress and returns the cartridge to its original location. You
can then activate the Global Spare drive (see Using a Global Spare Drive on
page 355). The aborted QuickScan process resumes when the Global Spare
drive is again available.
 A QuickScan using a Global Spare drive is limited to 10 minutes. If the
QuickScan exceeds this time limit, the operation is aborted and the cartridge
is returned to its slot. The library posts a message stating that the QuickScan
failed. Use FullScan to verify the cartridge.
