Symptoms

After replacing a drive acting as bridge drive with the library being online, one or all the below symptoms could be reported:

1. When accessing the library through BUI will be prompted with the message " Discovering ALL Library Components" and have access only to the Service tab.

2. Robot might get stuck or a tape might get stuck in the robot hand preventing the library to initialize.

3. Tape might get stuck in the mailslot.

Changes

  Replacing the bridge drive while the library is online.

Cause

The bridging tape drive is located in the top drive slot of the base module. The robot control is a SCSI Medium Changer device that appears as LUN 1 on a bridging tape drive. If the library is partitioned, there must be two tape drives in the base module, and each tape drive provides the robot control for its assigned partition.

Solution

If the failed drive is the bridge drive then the SL150 library must be taken offline to the host as replacing the tape drive will cause the host to lose connectivity to the SL150 library.  If the tape drive is not a bridging drive then it can be hot swapped.

The solution is to bring the library offline, unplug the drive, plug the drive back and bring back the library online.

Note: The SL150 can now have up to 8 partitions.  You are required to have a bridge drive for each partition. (10-Feb-2016)
