MSL2024 1 Drive 1840 backup failure

[CLEB]

I have an MSL2024 1 drive 1840 SCSI library that keeps failing at random points during the backup window.

It's attached via an HP SC11Xe in an HP DL580 G5 server.

I get an error "Unexpected SCSI Sense Code[ABSL:5040 CMD SC:28h 40]"

Firmware on the drive is B59W. I ran an HP LTT device read/write test and it passed after testing a full cartridge.

I've set the reg key for SCSI retry to 250.

Hi, they're not attached.

What about a wellness test from the OCP - does it pass that?

Are you attaching the ltt support ticket too?

[SUBHAJIT KHANBARMAN_1]

"I get an error "Unexpected SCSI Sense Code[ABSL:5040 CMD SC:28h 40]""

Where you have received the above error?

Can you please tell me what error code you have noticed in the OCP of the library?


Can you please send the L&TT support ticket for the entire library?

The error message is appearing in the ARCserve activity log.

[04/21 07:11:17 211c 1 WD 16316 16317 4] Unexpected SCSI Sense Code [ABSL:5040 CMD SC:28h 40]

[04/21 07:13:27 0b78 1 TK 16316 3] DRV:4 [HP Ultrium 4-SCSI B59W] recovered [1] error for [writing.].

Looks like the attachment wasn't added as it was too big.

Server is running W2K8 R2 with PSP8.70

I don't think there is any issue with the hardware as the ticket looks clean to me.

I just had another failure last night.

I will run another test with HP LTT on the full library.

I disabled the HP Insight Storage Agents service and I've had the first successful backup in five attempts.

Are you certain that you got the right SCSI registry entry for retries when busy set to 250? That behavior really sounds like the busy retry issue.

The operating system creates another entry every time you update drive firmware so there are often a lot of similar entries. I've seen a number of cases where the entry that the OS was using didn't get configured when there were multiple entries. To help with that we will be posting a tool shortly that will set the entry automatically but I don't have an official final copy of that tool that I can post yet.
