1. Select a node in the site to create a remote array RAID Manager instance.
2. Edit the /etc/services file to add an entry for the remote array RAID Manager instance.
The format of the entry must be:
horcm<instance-number> <port_number>/udp
For example:
horcm1 11001/udp #Raid Manager instance 1
NOTE: The UDP ports used for the local array RAID Manager and the remote array RAID
Manager must be different.
3. Create a RAID Manager configuration file for the remote array RAID Manager instance using
the RAID Manager configuration file template.
For example:
# cp /etc/horcm.conf /etc/horcm1.conf
4. Configure the following parameters in the RAID Manager configuration file:
• HORCM_MON
Enter the host name of the system on which you are editing the file and the TCP/IP port
number specified for the RAID Manager instance in the /etc/services file.
• HORCM_CMD
Enter the device file names for the command device configured to manage the remote
array.
• HORCM_LDEV
Enter the details of all the devices in the remote P9000 or XP array for all device groups
to be managed by the instance. To obtain this information, run the raidscan command
on a node that is connected to the remote P9000 or XP array.
• HORCM_INST
Enter the following local array RAID Manager instance information for this parameter:
<device_group_name>
<local_node_name><local_array_RAID_manager_instance>
5. Start the remote Array RAID Manager instance.
# horcmstart.sh <instance_number>
6. Update the HORCM_INST section in the local array RAID Manager instance file with the remote
array RAID Manager instance information.
It is recommended that you specify the remote array RAID Manager instance as the last entry
in this section of the configuration file.
<device_group_name>
<local_node_name><remote_array_RAID_manager_instance>
7. Restart the local array RAID Manager instance so that the new information in the configuration
file is read.
# horcmshutdown.sh <instance_number>
# horcmstart.sh <instance_number>
8. Repeat steps 2 to 7 on all other nodes in the primary site.
9. Repeat steps 2 to 7 on all nodes in the remote site.
