We have had our robotic arm fail five times over the last few months. Storage Tek keeps telling us that it is just that residue has built up on the gripper, but we don't buy it. They have replaced the arm once, and cleaned it several times and it still keeps failing. It did not start failing until the last library firmware upgrade. I am curious to know if anyone else is having this issue and if anyone knows a root cause. Details of the problem are below.
Environment:
NetBackup 4.5 FP5
Storage Tek L700E library at firmware level 3.06.00
IBM Ultrium LTO1 drives at firmware level 3481
Failures/error codes:
Backups fail with 52 (media mount timeout) errors. This is usually our first indication there is an issue
Ran robtest and received error "Logical unit not ready, Manual intervention required" message. If you go into "Drive info" on the control panel, you receive a targeting error"
Checked the Tape Library and the red "Service Required"
light was on. Opened the door on the Tape Library and there was the robot sound asleep
When you reset the library the robot comes back to life and errors go away.
Any help on this issue would be appreciated.
