Building Disaster Recovery Serviceguard Solutions Using Metrocluster with Continuous Access XP P9000 for Linux B.01.00.00

HP recommends configuring a remote array RAID Manager instance in all Metrocluster
configurations, especially in a 2-node configuration, as it is more robust. For more information
about configuring a remote array RAID Manager instance in Metrocluster, see “Configuring a
remote array RAID Manager instance” (page 29).
NOTE:
• Remote command device can be configured in Continentalclusters.
• Remote command device need not be configured when XP or P9000 Continuous Access
Journal replication is used.
Configuring a remote array RAID Manager instance
To configure the remote array RAID Manager instance in a Metrocluster environment with Continuous
Access XP or P9000:
1. Configure the command device to manage the remote XP or P9000 arrays. The XP array at
every site must have a command device exclusively for the nodes in the other site.
2. Configure the remote array RAID Manager instance on all the nodes in every site to manage
the remote XP or P9000 array. The RAID Manager instance that manages the local array is
referred as the local array RAID Manager.
3. Configure remote array RAID Manager instance in the /etc/mcxpca/raidmgr file for
automatic startup.
