Support for GeoCluster for Microsoft Windows
HP 3PAR Recovery Manager for Exchange supports the use of both Remote Copy and HP 3PAR
GeoCluster Software for Microsoft Windows:
•
When synchronous mode Remote Copy is used with HP 3PAR Recovery Manager for Exchange
and GeoCluster, you can use Recovery Manager to create virtual copies on both the production
system (the Remote Copy primary system) and the backup system.
•
When Synchronous Long Distance Remote Copy is used with HP 3PAR Recovery Manager
for Exchange and GeoCluster, you can use Recovery Manager to create virtual copies on all
three systems: the production system (the Remote Copy primary system), the synchronous mode
backup system, and the asynchronous periodic mode backup system.
Setting Up Remote Copy Volume Groups for Mailbox Databases/Storage
Groups
1. Identify the virtual volumes that contain the mailbox database/storage group and log files to
be copied.
2. Create one (and only one) Remote Copy volume group per mailbox database/storage group.
3. Add the virtual volumes belonging to the mailbox database/storage group files and log files
to the primary Remote Copy volume group, and add the associated secondary virtual volumes
to the secondary volume group on the backup server.
CAUTION: The relationship between mailbox databases/storage groups and Remote Copy
volume groups is 1:1.
•
You must add mailbox database/storage group files to a primary Remote Copy volume
group for Remote Copy to function.
•
You must add files from only one mailbox database/storage group to one primary volume
group.
◦ Do not disperse files from one mailbox database/storage group over multiple primary
Remote Copy volume groups.
◦ Do not add files from multiple mailbox database/storage groups to the same Remote
Copy volume group.
If the system fails to meet these requirements, it may result in data corruption and loss.
4. Synchronize the Remote Copy primary and secondary volume groups.
Recovering a Mailbox Database/Storage Groups from a Remote Copy
Backup Server
If a mailbox database/storage group crashes at the site that holds the production system (the
Remote Copy primary system), you can recover the data from the backup server at the remote site
as long as it is set up in an identical manner to the original production server.
NOTE: If you are performing a promote restore for volumes in a Synchronous Long Distance
Remote Copy relationship, you must manually stop Remote Copy before initiating the volume
promote restore.
1. On the backup server, use Recovery Manager to mount the virtual copy to the production
server.
2. Log on to the production server and stop the Exchange instance and its dependent services.
3. From the mounted virtual copy, manually copy all necessary mailbox database/storage group
and log files to the corresponding mailbox database/storage group location.
