• A disk group was deleted or disabled.
• A logical volume allocated to a disk group was added or deleted.
• A physical volume belonging to a disk group is added, deleted, or replaced.
• A change was made in the RAID Manager configuration definition file (
horcm
n
.conf
), such
as the adding or deleting of a pair volume.
•
If you made changes to a configuration involving an update of the dictionary map files, to restore
the data backed up before the change to a file server or database server, first restore the config-
uration for the logical volume manager and file system to the state that was in place at the time
the backup was created, and then perform restoration. Note that if you perform restoration incor-
rectly, a system inconsistency might occur. To review the configuration that was in place at the
time the backup was created, use the
drmfscat
,
drmsqlcat
, or
drmexgcat
command. For
details about how to use these commands, see the HP P9000 Replication Manager Software Ap-
plication Agent CLI Reference Guide. For details about restoration when a physical volume is re-
placed, see
Requirements and precautions when a disk group Is configured
When you operate Application Agent in a disk group configuration managed by Veritas Storage
Foundation, the following prerequisites apply:
•
The same OS, version revision, and service pack are installed on all the Windows servers subject
to backup and restoration by Application Agent.
•
The physical disk subject to backup and restoration does not include a system (OS startup) disk.
•
All the physical disks subject to backup and restoration are LUs of a storage system device and
for which a pair volume is defined.
•
The dynamic volume is a concatenated volume (simple volume or spanned volume).
• HP recommends that one disk group consist of one concatenated volume.
• Striped volumes, mirrored volumes, and RAID5 volumes are not supported.
•
You must dynamically recognize the secondary volume when backing up secondary volumes
(dynamic disk backup destinations) of multiple generations to tape.
Using dynamic disks in Veritas Storage Foundation
Prerequisites for the Veritas Storage Foundation environment and disk groups are as follows:
•
Veritas Storage Foundation with the same version revision and service pack is installed on all the
Windows servers subject to backup and restoration by Application Agent.
•
Do not back up and restore data with Veritas Storage Foundation functions because the disk group
configurations managed by Application Agent might be changed.
•
Disk group names must be unique in all the systems that back up and restore data. If multiple file
servers or database servers are sharing one backup server, the disk group names used by the file
server and database server might be duplicated in the backup server. If this occurs, Application
Agent is unable to uniquely recognize the disk groups in which data to be backed up to tape is
stored.
•
Application Agent cannot back up and restore primary disk groups.
•
Installing Veritas Storage Foundation enables you to use Veritas Enterprise Administrator instead
of Windows disk management. Do not use Veritas Enterprise Administrator during execution of
Application Agent.
