Using Microsoft Cluster Service or Windows Server Failover Clustering
If you are using Exchange Server 2003 or Exchange Server 2007, note the following points:
•
Among the cluster resource groups, the Exchange System Attendant resource and the Exchange
Information Store resource must be online during backup. If they are not online, the backup com-
mand (
drmexgbackup
or
EX_DRM_EXG_BACKUP
) will result in an error.
•
When using VSS, the following conditions must be satisfied regarding the relationship between
the cluster resource and the Exchange Information Store resource to be operated:
For Exchange Server 2003:
Except for the relationship between the cluster resource and the Exchange System Attendant
resource to be operated, do not set the Exchange Information Store resource to go offline
when a cluster resource goes offline.
For Exchange Server 2007:
Do not set the Exchange Information Store resource to go offline when the cluster resource to
be operated goes offline.
Cascade configuration
•
Backups in an SCC environment are supported.
•
Backups must be executed on the active server of a cluster.
•
A disk with Remote Copy defined must be registered as a disk resource of the cluster.
•
The primary volume of Remote Copy must be connected to the active server.
•
The secondary volume of Remote Copy must be connected to the standby server.
•
When you concurrently back up at both the local and remote sites, different backup servers must
be used at each site.
•
The Protection Manager service must be running at both the local and remote sites.
•
When you back up by using VSS, the
VSXPHORCMINST_REMOTE
system environment variable
must be set for the backup server at the remote site.
•
You must create a definition file for the cascade configuration. For details about creating a
definition file for the cascade configuration, see “
Creating a cascade configuration definition file
•
You must store the dictionary map files and backup catalog on different disks at both the local
and remote sites. These disks must be accessible regardless of whether the virtual server is online
or offline.
•
The dictionary map files at both the local and remote sites must be updated with the most recent
information.
•
The RAID Manager instance for managing Remote Copy must be active.
•
If the RAID Manager instance used for managing Remote Copy is the same as the RAID Manager
instance managed by Application Agent (the RAID Manager instance specified for the
HORCMINST
parameter in the RAID Manager-linkage definition file), after you update the dictionary map files,
you must use the
drmcgctl
command at both the local and remote sites to lock the Remote Copy
copy groups.
•
Before you back up, you must use the RAID Manager command to set the Remote Copy pair status
to
PAIR
.
•
Before you back up, you must conceal the secondary volume of the local copy at both the local
and remote sites.
•
When you back up, you must set the Exchange virtual server name to the
DRM_HOSTNAME
envir-
onment variable.
