MSL5052 tape library NSR reboot and error issue

MSL5052 tape library NSR reboot and error issue

Last night our MSL rebooted unexpectedly with the following error:

We are running Windows 2003 with DP 5.5. The MSL is fiber connected and zoned properly. I've looked around and seen that the CHK COND messages could be attributed to a firmware issue or the RsetPTRLO option on a connected servers' HBA. We have several servers zoned into the tape library but only 1 of them reported the reboot via an Insight Manager event. The Insight Manager trap flags are 16 for the drives and controller.

2004. 09/11/2006 07:05:10 37d19h14m46.66s CHK COND with Sense Key=0x3, ASC=0x11, ASCQ=0x0 from SCSI LUN 0/1/0

this is indicating a medium error read not recovered error


2002. 09/09/2006 09:13:03 35d21h22m40.15s SCSI UDC Error. Port 0 Target 0, S_ID 0xFFFFFF, CDB[0] 0x00, Device Type 31

This is indicating a Unexpected Disconnect on the device in SCSI Parallel port O

I think that you should troubleshoot your drive, or scsi connection between NSR and drive to see if errors on the scsi path cause trouble to the NSR and causing the reboot.

The cause may also be a bad cartidge.

You can use LTT and run acceptance test to identify the cause of the problem
