T074 - Drive Sled Auto-Leveling Failure
Description GUI Description: The drive sled assembly failed to automatically update its
firmware to the correct version.
Explanation: The normal auto-level process for a tape drive sled did not
work. When a drive sled is inserted into a booted-up library, or when a library
powers up, the firmware level of the tape drive sleds is checked to ensure that
it is consistent with the level required by the main library firmware. If the level
is not correct, the tape drive sled will be up-leveled or down-leveled
accordingly. A failure to set the correct firmware level in the sled results in this
RAS ticket.
Detection Scenarios Firmware that controls and performs drive sled firmware download cannot
successfully load a drive sled, and all recovery efforts fail.
Root Causes • Physical interruption of the code download process.
• Code bugs.
• Hardware failures that result in intermittent or failed communication between
library and tape drive sled.
Service Resolution
Steps
1 Perform DR033 -
Resolve Drive Sled Auto-Level Failure on page 382.
2 Clear the RAS ticket. Before replacing any parts, upgrade library and drive
firmware to the latest version. This will correct this issue in most cases.
Possible CRUs/FRUs Note: Read and perform all resolution steps before dispatching any parts.
Dispatch the first part listed below for replacement. If this does not solve the
problem, dispatch the second part, and so on, in order. Dispatch only one part
(or set of parts) at a time.
