Tape to Tape Drive Correlation

[csherwood]

We have a Win2k Master server here running NBU4.5 FP3, with Solaris, HP/UX and Windows Media servers, and I am getting alot of error 52's trying to mount tapes.

I have cranked up logging to see if I can find this, but I am having troubles cross referencing the data.

What I am trying to do is figure out which tape drive a tape was loaded into given the time and job logged. Like I said I have cranked up the logging on all the standard logs to 5 (maximum).

Any help you guys can provide would be greatly appreciated.

Thanks!

Have you cleaned all your drives?

I would also recommend upgrading to NBU 4.5 FP6

Personally - I would stay away from FP6 - There are know issues and you may get more 52 errors. Have you verified all communications using bpclntcmd?

 

[csherwood]

Yes. All communications are fine. The tape(s) in question will fail in one drive, but in a later job, work fine. I have 2 libraries with 6 drives each, so I am assuming it is working since it gets mounted in a different drive.

 

[PGPhantom]

If it is only one drive failing - You may want to consider replacing that drive as this may be hardware related.

I use to get numerous #52 errorcodes and it drove me batty. I have SSO and a tape SAN. I eventually minimized the occurrences by upgrading microde and zoning the drives to isolate windows and UNIX from sharing the same drives. I now only seem to get the errors on window media servers.
And even then I am still able to eventually get a good backup during the backup window because I retry failed backups at a rate of 3 tries every 2 hours.

Can you go into more details please? We're being pushed towards FP6 here to allow SSO under Windows 2003.
