Event Code Message Text and
Description
Details and Solution
2015 Top cover is missing. Install the top cover on the top module of the library. Also,
check the module interconnect cabling and module power
cabling. If the base module can’t detect both a top and bottom
cover, the accessor doesn’t move.
2016 Unit to unit not locked. Ensure that the alignment mechanism is engaged in every
module that is above another module in the library.
2017 Communication errors during
stack discover process.
• Ensure that all modules are powered and have the
interconnect cable properly attached.
• Ensure that the module alignment locks (at the rear of
module) are in the correct positions.
2021 Database access error. Restore a conguration backup and run a power cycle.
2022 Drive was hot-removed. Reinsert the removed drive at the same position as it was
removed.
2023 Internal Software error. Check for a new system Software version for upgrade.
2024 Unhandled Exception Check for a new system Software version for upgrade.
2027 Move failed pulling cartridge
from slot.
• Check for labels or cartridge misalignments that can prevent
the cartridge from coming out of the slot or drive.
• For proper operation, the accessor must be able to reach the
bottom of the library. Verify that no obstructions exist at the
bottom of the library or on the bottom cover of the library in
the path of the accessor.
1. To check for obstructions at the bottom of the library, rst
power off the library by pressing Power for 5 seconds and
select the Default Park location.
2. When the library is powered off, remove the left magazine
of the lowest library module, and verify that the entire area
of the bottom cover is free of any objects that might
obstruct the accessor's path.
3. After obstructions are cleared, replace the magazine, power
the library on, and after the library nishes initialization and
inventory, verify that no further critical events were
generated.
