Building Disaster Recovery Serviceguard Solutions Using Metrocluster with Continuous Access XP P9000 for Linux B.12.00.00

To configure the remote array RAID Manager instance for automatic startup:
1. Edit the following parameters in the configuration file /etc/mcxpca/raidmgr:
• START_RAIDMGR
Set this parameter to 1.
• RAIDMGR_INSTANCE
Specify all the RAID Manager instances that must be started during node boot-up. Include
the remote array RAID Manager instance number as the value for this parameter.
For example, if the instance number zero (0) is the local array RAID Manager instance and the
instance number 1 is the remote array RAID Manager instance then specify both the instances in
a comma separated list as RAIDMGR_INSTANCE parameter value in the /etc/mcxpca/raidmgr
configuration file as follows:
RAIDMGR_INSTANCE=”0,1”
Restrictions
Following are the restrictions that must be considered prior to configuring remote command device
in a Metrocluster:
• Always use a dedicated command device for the remote array RAID Manager instance.
• When using Extended SAN:
Ensure that only the command device is presented to the remote nodes.◦
◦ None of the replicated LUNs must be presented to the nodes in the remote site.
• While editing the Continuous Access device group configuration, the changes must be done
in the configuration files of both the RAID Manager instances, on all the cluster nodes.
