Information
Monitoring the Drives
The presence of cleaning cartridges results in the reporting of
additional status information in response to host-initiated Read
Element Status commands. This additional information is only
present in automatic cleaning mode and is suppressed in host-
initiated cleaning mode. The additional information may consist of
the Except bit being set and the Additional Sense Code and
Additional Sense Code Qualifier values being filled-in as well as
possible changes to the Access bit (described below).
A storage element (bin) that contains a cleaning cartridge that is not
used up has the Access bit set to 1, the Except bit set to 1, and the
status set to Cleaning Cartridge Installed (ASC=30 ASCQ=03).
A storage element that contains a cleaning cartridge that is used up
has the Access bit set to 1, the Except bit set to 1, and the status set
to Operator Medium Removal Request (ASC=5A ASCQ=01).
A storage element that is empty but is the home location for a
cleaning cartridge that is currently being used in a cleaning
operation has the Access bit set to 0, the Except bit set to 1 and the
status set to Cleaning Cartridge Installed (ASC=30 ASCQ=03).
A data transfer element that is currently being cleaned as part of an
automatic cleaning operation has the Access bit set to 0, the Except
bit set to 1, and the status set to Cleaning Cartridge Installed
(ASC=30 ASCQ=03).
In host-initiated cleaning mode, the host is responsible for
monitoring the drives to determine when a drive needs to be
cleaned.
In automatic cleaning mode, the library monitors the drives to
determine when a drive needs to be cleaned.
Each drive "CLEANING_ REQUIRED" flag is checked at the
completion of an inventory.
A specific drive's "CLEANING_REQUIRED" flag is checked at the
completion of a Move Medium command involving that drive.
