Test Name Description
EXERCISE MECH Runs the VERTICAL TEST, TRANSLATE TEST, MAGAZINE IO, and DRIVE
IO tests. Each test is run one time per test loop.
EXCHANGE DEMO Used by service personnel only. Do not run this test if the library contains
tape cartridges with file system data on them. This test moves randomly
chosen cartridges to random storage slot locations. This test displays FAIL if
there are no cartridges in the library or if all storage slots are full. For best results,
the library should contain as many cartridges as there are drives, plus two
additional cartridges. The transport must be empty.
IO DRIVE Makes a combination of moves with a PASS/FAIL result. If the drives are
empty, a tape cartridge is moved from a randomly chosen full slot to a randomly
chosen drive. If the drives are full, a tape cartridge is moved from a randomly
chosen drive to a randomly chosen storage slot. It then moves the cartridge back
to its original location. This test displays FAIL if there are no cartridges in the
library or if all storage slots are full. The transport and the mailslot must be
empty.
IO MAGAZINE Makes a combination of moves with a PASS/FAIL result. It moves a tape
cartridge from a random full slot to a random empty slot. It then moves the tape
cartridge back to its original storage slot. This test displays FAIL if there are no
cartridges in the library or if all storage slots are full. The drives, transport, and
the mailslot must be empty.
IO MAILSLOT Makes a combination of moves with a PASS/FAIL result. It moves a tape
cartridge from a random full slot to the mailslot. It then moves the tape cartridge
back to its original storage slot. This test displays FAIL if there are no cartridges
in the library or if all storage slots are full. The drives, transport, and the mailslot
must be empty.
