Library Self-Tests
The self-test diagnostic utility is intended to help diagnose basic problems with the
library. A self-test is typically run after the library is installed. It can be run whenever
necessary.
Note – The library self-test routines are non-disruptive.
Library self-tests involve the following process:
1. Checks the communication path between the library controller, drives, and HandBot.
2. Performs get and put operations to check the health of the HandBot and CAPs. This
includes get and put operations from a reserved cell to a random empty:
■ Storage cell
■ CAP cell
■ Corner cell
3. Performs a full library audit.
4. Performs mounts and dismounts of diagnostic cartridges for all the drives installed
in the library.
Note – The self-test will not start unless a diagnostic cartridge is found in the reserved
cells.
Note – The self-test is repeated for each drive type if a compatible diagnostic cartridge
is found in the reserved cells. If a diagnostic cartridge is not found for a drive type, the
mount/dismount operation is skipped for the drive.
