[Veritas-bu] NBU_SNAP issue

[Evsyukov, Sergey]

Hello, we have business important issue with advanced client.

 

OS - Solaris 9

NBU - 5.1MP2

SNAPSHOT METHOD - NBU_SNAP

 
Backup failed with STATUS = 156 In ~/log/online_util/log.101606 we have found:
11:57:43.833 [24864] <2> onlfi_vfms_logf: INF - nbu_snap_freeze: Cannot turn on snapshot; snapshot source=/export, cache =/dev/vx/rdsk/bishouse_dg_01/bishouse_vol_01, snap error=5

When we have tryed to create snapshot from CLI, we have got:
[EMAIL PROTECTED] # /usr/openv/netbackup/bin/driver/snapon /export /dev/vx/rdsk/bishouse_dg_01/bishouse_vol_01
matched /export to mnttab entry /export mount device: /dev/vx/dsk/exportdg/export fstype: ufs
snapon on /export failed err=11 snerrno=5

 

In /var/adm/messages we have found:
Oct 16 12:18:40 sf6800a snapctl: [ID 803675 kern.warning] WARNING: addcache: id 22604 cache path = /dev/vx/rdsk/bishouse_dg_01/bishouse_vol_01

/dev/vx/rdsk/bishouse_dg_01/bishouse_vol_01 seems good:

 

[EMAIL PROTECTED] # dd if=/dev/zero of=/dev/vx/rdsk/bishouse_dg_01/bishouse_vol_01 bs=65536 count=1024
1024+0 records in
1024+0 records out

 

What can be reason of problem?

 

Thanks for any help, Sergey
