Product & Version: NVBU 8.5
OS Version: ALL
Module & Version: NDMP V7.1.11 onwards
Application version: DARTOS 5.6
Symptoms:
Netvault binary log lists the following
Error 2010/03/04 12:24:52 39 Data Plugin axvc01 Data operation halted due to unrecoverable internal NDMP server error
establish whether this is a VBB dump by checking the ndmp restore request within the binary log
Job Message 2010/03/04 12:24:47 39 Data Plugin axvc01 Restore Request
expand the contents by double clicking on the ! and check for the value VBB = Y
i.e.
Restore Environment:
FILESYSTEM = /fs_at_cifs01
LEVEL = 0
UPDATE = Y
HIST = Y
SNAPSURE = Y
VBB = Y
MD_SIZE = 110632960
MD_SIZE_HIGH = 0
TYPE = dump
RECURSIVE = Y
DIRECT = Y
check whether the file system/volume that was backed up was deduplicated.
if so the emc filer syslog will list the following:
2010-03-15 16:07:12: VBB: 6: Recursively creating files and dirs
2010-03-15 16:07:12: VBB: 3: Cannot set offline data for inode 38 (UknownProtocol)

2010-03-15 16:07:12: VBB: 3: Restore aborted
Explanation:
This is an EMC limitation with De-duplicated file systems - a standard restore from a VBB dump is not possible. A full destructive restore must be performed.
