Chapter 9 — Configuring and Using Media Lifecycle Management Using PostScan
December 2019 User Guide—Spectra T200, T380, and T680 Libraries
289
When the PreScan process is complete, the library stores the tape health
information for the cartridge in the MLM database. It also writes the MLM
data to the cartridge MAM. When the drive ejects the cartridge, the library
returns it to its original slot.
Requirements for Use When using PreScan, make sure that you consider
the following requirements:
USING POSTSCAN
This section provides detailed information about how PostScan operates,
as well as prerequisites for using PostScan and performing manual
PostScan operations.
Notes: PostScan is not supported for partitions with TS11xx
technology drives.
PostScan and Spectra SKLM encryption key management
cannot be configured for use in the same partition.
Consideration Requirement
Drive Firmware LTO-4: requires 97F9 or later firmware.
LTO-5: requires B170 or later firmware.
LTO-6 or later: supported with any firmware.
TS11xx technology: supported with any firmware.
Updating MLM
Data on MAM
Updating the cartridge MAM requires the cartridge to be write-enabled.
Important: If a cartridge is write-protected when it is inserted into a drive, the
information about the cartridge is added to the MLM database, but the library
cannot update the MLM information on the cartridge’s MAM.
Drive Availability The media discovery process loads the cartridges in the partition into the drives
assigned to that partition. While in use for PreScan, host moves to the drives
being used are delayed until the PreScan operation completes. Spectra Logic
highly recommends that you perform the manual media discovery process
when your storage management software is not accessing the library and the
library is idle.
Auto Drive Clean
Restrictions
Auto drive clean operations do not start while PreScan is running on any
partition that is associated with the cleaning partition. If a drive requires
cleaning, wait until the PreScan operation is complete and then manually clean
the drive.
Cleaning Partitions The PreScan feature cannot be enabled for a cleaning partition and does not
affect the operation of cleaning cartridges.
PostScan is enabled and configured for each individual partition. PostScan does not
operate until the PostScan option is selected and one or more triggers are specified for
the partition (see Enable and Configure MLM PreScan and PostScan on page 197
).
