UNIX and Flashbackup

Level 4


We had successfully tested Flashbackup using NetBackup 6.5.5 on UNIX media server. 

NBU Master - Windows 2003 using 6.5.5

NBU Media Server - UNIX HP-UX B.11.31 using 6.5.5

In the Policy it was setup:

Atrributes - Flashbackup

Backup Selections:




Current Setup:

NBU Master - Windows 2003 using 7.5.1

NBU Media Server - UNIX HP-UX B.11.31 using 7.5.1

Backup Selections:




Policy is the same.  When I run the job, it produces an error code of 12 (file open failed).  Also when I modify the policy, the system tries to validate the policy and I get this: Snapshot could not be created with VxFS_Snapshot method.  When I deselect "Perform snapshot backups" under Snapshot client, the validation is ok but I still get the same error.

Any thoughts of what is going on?

I wonder if these multi-pathed disks are supported?

Maybe Chris can help here:

In Snapshot Client Admin Guide I see the following:


FlashBackup supports the following I/O system components: ufs, VxFS, and
Windows NTFS file systems, VxVM volumes and LVM volumes, and raw disks.
Other components (such as non-Veritas storage replicators or other non-Veritas
volume managers) are not supported.
When I look at the Snapshot Client CL, I cannot find FlashBackup support for HP-UX on anything other than VxVM volumes. 
(not the easiest doc to read/search...)

This is way over my head.  :) 

I guess one thing I'm confused about is your original post's CACHE variable was set in a way that specified NOT the multipathed....err, path... but one of its component paths, /dev/dsk/c4t0d0.

It looks like you changed it to /dev/rdisk/disk14 when you created a new policy from scratch?

There appear to be a lot of floating variables here - might be time to call support and open a case.  (They might very well tell you what Marianne concluded - that this isn't a supported configuration - in which case I wish I could tell you why it worked in 6.x but doesn't in 7.x, but unsupported configurations are usually unsupported with good reason)

The server was rebuilt from scratch but it was on HP-UX 11.23 and needed to be on 11.31.  That might explain the different paths.  I will open ticket and reference this thread.

Case #03211274 was created. 

Side note, I'm not a fan of the new method to submit tickets online. 


The case # is to create my access to view support

Don't tell anyone, but I share your sentiments... I had the same experience a couple of weeks ago. Found out that it was the actual case #.
