Operations
When an AML archive Standard Audit is performed, the
archives require that no media be mounted before executing an
audit. If any media are mounted, the audit fails. If a mount
request is issued while an audit is in progress, the mount will
fail.
Under normal conditions, VolServ software begins the audit by
directing the archive to perform a physical audit and report the
results. A mounted medium is not scanned by any automated
archive robot, but the AML AMU does not report the medium
present in the drive. Therefore, VolServ logic assumes the
medium is not present in the archive and logically ejects it from
the VolServ database. However, the medium is still present in
the AML archive and database.
To prevent an audit from occurring when media are mounted,
VolServ uses information from the AML AMU. The AML
database shows mounted media in two tables: one for being in
the archive, another for being mounted. VolServ first retrieves
the mount table information. If any media are in the table, the
audit fails.
Remap Audit During a Remap Audit, automated archives with their own
internal databases report the contents of their databases. These
archives include the DataTower, StorageTek ACS product
family, and AML archives.
VolServ database is updated to reflect the reported information.
No robotic movement is required when performing a Remap
Audit. This process takes considerably less time to perform than
a Standard Audit. It should be performed when the VolServ
database is suspect but the archive database is intact.
