Dell EMC ML3 Tape Library: User's Guide
Details and Solution
v Review test requirements and retry the test.
v If the test continues to fail check for accessor obstructions or
other accessor problems.
v For proper operation, the accessor must be able to reach the
bottom of the library. Verify that no obstructions are 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, first
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 any obstructions are cleared, replace the magazine,
power the library on, and after the library finishes
initialization and inventory, verify that no further critical
events were generated.
Ensure that the spooling mechanism is fully seated in the base
module and installed correctly to the accessor assembly.
Remove all bottom covers except for the bottom module in the
library.
Remove all top covers except for the top module in the library.
Install the bottom cover on the bottom module of the library,
also check the module interconnect cabling and module power
cabling. If the base module cannot detect both a top and bottom
cover, the accessor does not move.
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 cannot detect both a top and bottom cover, the
accessor does not move.
Ensure that the alignment mechanism is engaged in every
module that is above another module in the library.
v Ensure that all modules are powered and have the
interconnect cable properly attached.
v Ensure that the module alignment locks (at the rear of
module) are in the correct positions.
Restore a configuration backup and run a power cycle.
Reinsert the removed drive at the same position as it was
removed.
Check for a new system software version for upgrade.
