NBU 7.1.0.1 - W2k8 Error 191 during duplication

Lee_C
Level 5

We are observing error 191 when duplicating to tape (copy3).

We have a remote site which backs up to an MSDP pool, which duplicates via a SLP to a PureDisk unit in the HQ, the image on Puredisk is then further duplicated to tape.  Backing up the same data further to another Puredisk as copy 3 instead of tape is sucessful

 

Remote site Backup - (MSDP)

     Duplication - HQ Site (PureDisk)

              Duplication ---> Tape (StorageUnitGroup)

 

Environment

Master/Media NBU7.1.0.1 on W2k8 - VMware, SQL and Exchange agents, MSDP

OCA 7.1.0.1 + ET2396696_1 on W2k8R2

PureDisk 6.6.1.2  + EEB20

I have read articles which recommend editting the registry in Windows 2003 as described here: http://support.microsoft.com/kb/304101/en-us .  We are using Windows 2008 where the memory management is completely different so wondered what advice should be done here.

 

Thanks

It clold be a damages or a missing backup image. I see "cannot read image from disk, Invalid argument" in the text provided.

Are you able to verify the image. GUI -> Catalog -> Verify

Hi Nicolai,

I ran a verify and the copy 2 that is used to duplicate fails to tape verifies

However also if we change the SLP such that the copy 3 is not tape but another Puredisk at another remote site, that completes sucessfully.

That really sound strange. I am somwhat concerned about the healt of copy 2. What if you restore from copy2 - does that work.

How to restore from a different copy of the backup

Thanks again!

I'm going to run a few verification tests starting with copy 1 and also verify the status of what appears to be a good copy 2 and copy 3 when not using tape as a comparision.

 

I'll update this thread later.

If you can perform restore test from all copy's, you might consider to open a support case regarding the writing to tape.
