Configuring hosts
Configure native or installed multipathing software on all hosts in remote replication configurations.
Multipathing software redirects I/O requests from a failed path to the alternate path, preventing
disruptions in data access if the path to the array fails. See your multipathing documentation for
installation and configuration information.
Configuring disk groups for remote replication
Disk groups are created to meet performance and single array availability needs. However, you
must consider HP P6000 Continuous Access requirements when choosing a disk group for the
write history log. There must be enough space in the disk group for the log. Of additional concern
may be the destination array disk group, which must contain enough disk drives to satisfy the write
I/O load imposed by HP P6000 Continuous Access. HP P6000 Continuous Access should be
taken it into account when evaluating the overall performance of the array. For more information,
see “Planning disk groups” (page 35).
Creating and presenting source virtual disks
Virtual disks, created using HP P6000 Command View, are the primary storage objects on the
array. When creating source virtual disks for a DR group, select the preferred controller carefully.
Balancing DR groups across controllers contributes to the efficient utilization of remote replication
resources and balances the I/O load. You should ensure that the DR groups imposing the heaviest
workloads are distributed across the controllers.
For information on creating virtual disks, see the HP P6000 Command View Online Help.
