the same nodes. This is done by editing the rc script /etc/rc.config.d/raidmgr. Set the START_RAIDMGR parameter to 1, and define RAIDMGR_INSTANCE as the number of the Raid Manager instances being used. By default, this is zero (0).
Following is an example of the edited configuration file for XP Raid Manager instance. In this example, the instance number zero (0) is the local array RAID Manager instance and the instance number 1 is the remote array RAID Manager instance.

Configuring a remote array RAID Manager instance
In a Metrocluster configuration, the remote array RAID Manager instance must be configured in the following manner:
1.The XP array at each site must have a command device exclusively for the nodes in the other site.
2.As shown in Figure 31 (page 171), on all nodes in each site, a new RAID Manager instance must be configured to manage the remote P9000 or XP array, which is the remote array RAID Manager. The RAID Manager instance that manages the local array is referred to as the local array RAID Manager.
