Microsoft Cluster Server Integration
Chapter 13620
To distinguish between local cluster node disks and shared cluster node
disks, Data Protector queries the MSCS database for a list of physical
cluster disk resources. All cluster disks presented as proprietary cluster
disk resources (e.g. NetRAID 4 disk type) are treated as local cluster
node disks.
However, when creating a backup specification, you can see three or
more systems that can be backed up:
• Primary node (selected when backing up local disks)
• Secondary node(s) (selected when backing up local disks)
• Virtual server(s) (selected when backing up shared disks)
Backing Up Local Disks
To back up cluster local disks, proceed as follows:
1. Install and configure the Data Protector Disk Agent and cluster
component on each cluster node that has the local disks you want to
back up.
2. Configure a backup specification for specific cluster node and select
which of its local disks you want to back up.
Backing Up Shared Disks
To back up cluster shared disks, proceed as follows:
1. Install (locally) the Data Protector cluster client software on each
cluster node. See the HP OpenView Storage Data Protector
Installation and Licensing Guide for instructions.
2. Import virtual server hostname (Microsoft Cluster Server) to the
Data Protector cell. See the HP OpenView Storage Data Protector
Installation and Licensing Guide for instructions.
3. Configure a backup specification for the virtual server and select the
shared disks you want to back up.
Managing Cluster-Aware Backups
In the Data Protector cluster Cell Manager, the backup session is
cluster-aware. You can set options that define backup behavior if a
failover of Data Protector or other cluster-aware applications occurs.
