Mount Failed Errors

[Jon_Birnbaum]

Other than a bad tape or drive, is there anything else that would cause "Mount Failed - User canceled a Physical Volume Library operation" errors?

I administer multiple locations, each of which have the identical hardware configuration (same servers, same tape drives, same media), and I'm plagued by Mount Failed errors at least 2-3 times a week at every site. There doesn't seem to be anything consistent about the errors, either. The tapes are being swapped in a weekly rotation at each site and the errors do not always occur on the same day each week.

At this point, I've tried new tapes and have swapped one of the tape drives (with the identical model), but this does not fix the problem. Any help would be much appreciated.

Hello,

Check if the following applies.

(title) User canceled a Physical Volume Library operation" (a000810f HEX or e000810f HEX) is reported in the backup job log when attempting to run a backup operation.

Thanks for the response. Unfortunately, I don't believe that document applies to this situation. I have tried rotating in new tapes, swapping the tape drive, and have verified that write protection is not enabled on the tape.

We are using version 9.00 Build 4367. Could an issue like this be addressed by upgrading? Or are there any other software-related steps I could try to help troubleshoot the problem?

Thanks for the links. I'm currently looking into whether or not I'm able to upgrade all locations to the v9.1 version.

Have you seen the v9.1 upgrade resolve "Mount Failed" or similar issues for other people? Is there anywhere I can read over a list of fixes between v9.0.4367 and v9.1.4691?

Hello Jon,

Backup Exec v9.0 4367 being the older version, it is always better to have the latest version with oneself. Lot of issues are resolved with version 9.1.

The error you are getting is generally reported if there is some problem with the drive or media, however it can have verious other reasons possible as well. Therefore, you can try upgrading to BE v9.1 and check the results.

Hope this answers your question.

Regards
