T070: Library Control Path Failure
Description GUI Description: The library control command path through a tape drive has
failed.
Explanation: The library media changer control path through a drive has
failed. The host that owns and runs the logical library can no longer be
expected to be able to control the library. The control path must be fixed or a
user could choose to switch the control path to a different drive within the
same logical library.
Detection Scenarios
1. The loss of communications between the library and the drive sled
2. The loss of communications between the drive sled controller board and
the drive brick.
Root Causes
1. Various hardware problems inside the drive sled.
2. Tape Drive (brick) firmware problem
3. Drive sled firmware problem
4. Library communication firmware problem
5. Drive Sled Interface Board (DSIB) hardware problem
6. Loss of power to sled (DSIB 48 V fuse)
Possible CRU Replacement Drive Sled
Resolution
v Update drive firmware (see “Updating Drive Firmware” on page 7-26.
v Update library firmware (see “Updating Library Firmware” on page 7-25.
v If the problem still exists, replace the drive sled (see “Drive Sled” on page
8-43).
T071: Missing Power Supply
Description GUI Description: A previously installed power supply is missing.
The library can no longer detect the presence of a power supply that was
previously physically installed and logically added to the system.
Detection Scenarios Regular polling between LCB and power supply checks for presence of the
power supply.
Root Causes
1. Power Supply has been physically removed after being added to a
powered ON system.
2. Hardware failure inside supply
3. Hardware failure in library side connector of other electronics.
4. Disconnected module terminator or module-to-module cable.
5. Damaged module terminator or module-to-module cable with bent or
broken pins.
Possible CRU Replacements
1. Module Terminators and Module-to-Module Cables
2. Power Supply
Resolution Perform “DR022: Resolve Missing Power Supply” on page 6-68.
