Audits and Initialization
The term
audit
refers to the process of reading and cataloging all cartridges
within a library or verifying cartridge locations—the physical inventory.
An SL8500 library is capable of storing all cartridge locations within the library
on the HBC card—the library controller. The physical inventory contains:
•
Volume serial numbers (VOLSERs) or identification (VOLIDs)
•
Internal address locations (library, rail, column, side, and row)
•
Verified status (as true or false)
Audit Conditions
The library audits all cartridge locations in all areas of the library, including the
slots in the storage and reserved areas when:
•
The library initializes at power-on
•
After either one or both access doors are opened and closed
•
An audit request is made through Library Console
Audit Types
There are three types of audits that the library performs:
Note:
Eight HandBots can audit the library quicker than four HandBots.
Physical audit
Physical audits are when the HandBots:
•
Scan the cartridge locations in the library
•
Verify the volumes
•
Update the HBC card inventory
•
Set the status of the cartridge location to true
Verified audit
Verified audits are invoked from the Library Console and
validate
the status of a specific cartridge slot or range of slots.
Virtual audit
Virtual audits are invoked from the Library Console and
display
the
cartridge inventory in the console screen.
Important:
After the initialization is complete, the audit is then performed as a background
operations—it is
not
necessary to wait for an entire audit to complete before using
the library.
Shortly after the SL8500 begins initialization—after closing the front door or
powering-on the library—the SL8500 can begin to perform mount and dismount
requests to the tape drives. This is because after the initialization, the SL8500 uses
its existing database from a previous audit to perform any requests.
If cartridges have not been moved, removed, or added, then all subsequent
movement requests can proceed without interruption.
