HP P9000 Replication Manager Software 7.3.1-00 Configuration Guide

3. To perform restore when a cluster source is online, the Microsoft Cluster Service correction
module (Hotfix 903650) is required. Windows Server 2003 with Service Pack 1 or Windows
Server 2003 R2 is the prerequisite OS,
4. This is supported only when using the Application Agent CLI.
Cluster considerations
The following considerations apply to cluster support and operations:
• Application Agent supports both mutual standby cluster configurations (Active-Active) and opera-
tional standby cluster configurations (Active-Passive). However, For the cluster configuration,
Hitachi Replication Manager Software (Server) supports the “Active - Passive” configuration only.
• To restore backup data, the database must be taken offline. If a database is taken offline while
the cluster resources that are monitoring the database are still online, a failover will occur. This
usually requires controlling control cluster resources manually. With Application Agent, cluster
resources that monitor the database are automatically taken down and brought back online
whenever Application Agent is used to perform a backup or restore operation for data.
• In a cluster environment using MSCS/MSFC, you can choose whether to perform a restore oper-
ation while the cluster resources that monitor the database are online or offline. For a restore op-
eration in which the cluster resources are offline, you need to take all the databases that are using
the database services offline. However, for a restore operation in which the cluster resources are
currently online, you only need to take the databases offline that are involved in the restore oper-
ation.
• You can put together a cluster configuration using only database servers. You cannot allocate one
cluster server to a database server and the other cluster server to a backup server.
• Depending on the storage system type and features of the operating system, you might not be
able to perform a restore operation while the cluster is online.
Virtual environments supported by Application Agent
This section describes the following virtual environments supported by Application Agent:
• VMware ESX/ESXi Server, page 70
• Windows Server 2008 Hyper-V, page 72
VMware ESX/ESXi Server
Application Agent supports a Windows environment that functions as a guest OS. If provided as a
guest OS of the virtual server products, VMware ESX/ESXi Server 4.x and 5.x are also supported.
The following notes apply:
• Application Agent does not support VMware FT (Fault Tolerance).
• Do not run VMware live migration (VMware vMotion) and Application Agent at the same time. If
you run both concurrently, execution of Application Agent might fail. In such a case, please take
action according to message shown in the troubleshooting information.
• When applying the VSS correction module that includes Hotfix 940349, please apply the module
on all servers using VSS.
• Application Agent can only perform backups of RAW LUNs to which RAW device mapping has
been applied by using the physical compatibility mode).
• For VMware ESXi 5.0, configurations are not supported in which a software FCoE adapter is used
to connect a primary or secondary volume to a database server, backup server, or pair management
server on a guest OS.
