HP XP7 Replication Manager Configuration Guide (TK981-96012, May 2014)

Environment variables
Do not specify HORCMINST or HORCC_MRCF in a system environment variable. Also, do not specify
HORCM_CONF or HORCMPERM in a system or user environment variable.
HORCM options and RAID Manager
HORCM_DEV, HORCM_LDEV, or HORCM_LDEVG need to be specified in the configuration definition
files of RAID Manager instances used by Application Agent.
If you are going to manage a copy group defined by device group, HORCM_LDEVG needs to be
specified in both the P-VOL and S-VOL configuration definition files. (If you omit HORCM_LDEVG, the
P-VOL might be disconnected from the database server when you perform an Application Agent
operation.)
Make sure that there are no copy pairs consisting of disks that are not connected to the server in the
database server and the file server.
Copy pairs and backup/restore operations
A copy pair that is a target of backup and restore operation cannot be assigned as a network drive.
The P-VOL of a file system that is a target of backup and restore operations needs to be mounted.
Application Agent versions on database and backup servers
The same version of Application Agent must be installed on database and backup server pairs. Do
not, for example, install version 6.3 on the database server and 6.4 on the corresponding backup
server.
Remote copy type support
Microsoft Exchange Server uses VSS to create replicas. Because VSS only supports Cnt Ac-S for remote
copies, Replication Manager must use Cnt Ac-S to create remote replicas. (Cnt Ac-A and Cnt Ac-J
remote replicas are not supported. VSS does not allow the split time to exceed 10 seconds, and these
copy types cannot meet this requirement.)
Because Microsoft SQL Server does not use VSS (it uses VDI), there is no limitation on the remote copy
type for linkage with Microsoft SQL Server. Cnt Ac-S, Cnt Ac-A, and Cnt Ac-J are also supported.
Replica operations between storage systems
Application Agent is compatible with Continuous Access Synchronous and Continuous Access Journal
backups to (and restorations from) remote site storage systems, for when a failure occurs on a local
site storage system. Depending on the DBMS product linked to, different volume replication functions
can be used:
• Exchange Server: Continuous Access Synchronous
• SQL Server: Continuous Access Synchronous and Continuous Access Journal
Copy types supported for replica operation
The following system configurations can be used to perform backups and restorations between storage
systems:
• Continuous Access Synchronous or Continuous Access Journal configurations (basic)
• Business Copy and Continuous Access Synchronous multi-target configurations
• Business Copy and Continuous Access Journal multi-target configurations
• Continuous Access Synchronous and Continuous Access Journal multi-target configurations
