Resolving Conflicting Backups for a Disk Group
In some circumstances where disks have been replaced on a system, there may exist several
conflicting backups for a disk group. In this case, you see a message similar to the following
from the vxconfigrestore command:
VxVM vxconfigrestore ERROR V-5-1-6012 There are two backups that
have the same diskgroup name with different diskgroup id :
1047336696.19.xxx.veritas.com
1049135264.31.xxx.veritas.com
The solution is to specify the disk group by its ID rather than by its name to perform the
restoration. The backup file, /etc/vx/cbr/bk/diskgroup. dgid/ dgid.dginfo, contains a
timestamp that records when the backup was taken.
The following is a sample extract from such a backup file that shows the timestamp and disk
group ID information:
TIMESTAMP
Tue Apr 15 23:27:01 PDT 2003
.
.
.
DISK_GROUP_CONFIGURATION
Group: mydg
dgid: 1047336696.19.xxx.veritas.com
.
.
.
Use the timestamp information to decide which backup contains the relevant information,
and use the vxconfigrestore command to restore the configuration by specifying the disk
group ID instead of the disk group name.
