HP P6000 Continuous Access Implementation Guide (T3680-96431, August 2012)

Presenting destination virtual disks
After creating the DR groups, you can present the destination virtual disks to the remote hosts in
any of the following modes. You can use HP P6000 Command View, HP P6000 Replication
Solutions Manager, or HP Storage System Scripting Utility to present destination virtual disks to
remote hosts.
• None—The virtual disk cannot be presented to any hosts. (HP Storage System Scripting Utility
uses the term “disable” for this mode.)
• Read Only—The virtual disk can be presented to hosts for read only.
• Inquiry Only—The virtual disk can be presented to hosts for SCSI inquiry commands only. No
reads or writes are allowed. (HP P6000 Replication Solutions Manager uses the term “No
Read” for this mode.)
NOTE: A destination DR group member should not be presented to the same host that is accessing
the source member of the DR group if the presentation mode is Read Only or Inquiry Only.
Backing up the configuration
Back up your storage and replication configuration now and whenever it changes. Regular backups
are essential for effective disaster recovery. You can use the initial backup to re-create the
configuration on remote and standby management servers. For backup procedures, see “Backing
up replication configuration” (page 126).
Setting up remote and standby management servers
Use the backup from the local management server to duplicate the replication configuration on
remote and standby management servers. Before importing the configuration from the local instance
of HP P6000 Replication Solutions Manager, you must assume active management of the arrays
in the configuration using HP P6000 Command View on the remote or standby management server.
For the procedure for acquiring control of the arrays, see the HP P6000 Command View User
Guide.
After setting up all management servers, acquire control of the arrays on the local management
server. Only one management server at a time can manage an array.
Testing failover
Before you use the new DR groups, practice both planned and unplanned failovers. For failover
procedures, see “Planned failover” (page 105) and “Unplanned failover” (page 108).
