Not getting much help from support so I thought I would post here.
First the infrastructure layout: We have two dedicated proxies direct connected to two HP tape libraries. All equipment is new and dedicated. Everything worked on the updated version of 9.0.
After upgrading to 9.5 all tape jobs failed with various errors, the new tapes in the drive were retired by VEEAM and set as "corrupted". The first errors were:
- Code: Select all
12/5/2016 9:08:39 PM :: All tape drives are disabled.
12/5/2016 9:48:22 PM :: Library HP 1x8 G2 AUTOLDR 4.50 does not contain any enabled tape drives
12/7/2016 5:37:48 PM :: No tape libraries are online
I figured a good firm reboot and kick in the pants for all equipment might be in order as is sometimes the case after upgrades. Two full cycles down on all related equipment, new tapes, new catalogs, and then this error:
- Code: Select all
12/8/2016 9:29:09 AM :: TapeDrive alert: Media statistics have been lost at some time in the past.
12/8/2016 9:59:06 AM :: Failed to prepare to start new tape session: Tape positioning error: Tape error: '23' (Data error (cyclic redundancy check).)
Tape positioning error: Tape error: '23' (Data error (cyclic redundancy check).)
12/8/2016 9:59:18 AM :: TapeDrive alert: The tape drive is having problems reading data. No data has been lost, but there has been a reduction in the performance of the tape..
12/8/2016 9:59:18 AM :: TapeDrive alert: The operation has stopped because an error has occurred while reading or writing data that the drive cannot correct..
12/8/2016 9:59:18 AM :: TapeDrive alert: Your data is at risk:. Copy any data you require from this tape. Do not use this tape again. Restart the operation with a different tape.
12/8/2016 9:59:18 AM :: TapeDrive alert: The tape is damaged or the drive is faulty. Call the tape drive supplier helpline..
Now, to have 2 physically different tape drives and server proxies go bad at the exact same time? Immediately following a software upgrade? Doubtful. So I started trying the jobs manually one at a time. Success! Tape backups work.
Two jobs active? Fail
So what seems to happen is the jobs will complete at 99% and wait for the success message, but before that job is complete at 100% - the next job kicks in, takes over the tape drive and that's when the errors start to kick in. I'm not sure, but it seems you need to wait for one job to complete successfully before firing off the tape drive again.
Support ticket has been entered last week, but no progress to report. Any help is greatly appreciated.
