and that XP RAID Manager instances include the device group, configured for the web server
service group. To switch the web server service group, enter:
#hagrp –switch CLX_WEB_SERVER –to system_name

Configuring the pair/resync monitor
The pair/resync monitor is a service that verifies that disks are in the pair state, and resyncs them
when necessary. The pair/resync monitor determines whether the requesting server is allowed access
to the pair/resync monitor. To access the pair/resync monitor, you must update the remote access
hosts file and configure the pair/resync monitor port.
Updating the remote access hosts file
Enter the names of the remote systems in a remote access hosts file.
1. Open the /etc/opt/hpclx/conf/clxhosts file.
2. Enter each host name on a separate line.
You can leave blank lines, but do not enter comments. For example:
# cat /etc/opt/hpclx/conf/clxhosts
dcBserver
dcAserver
Configuring the pair/resync monitor port
Enter the port that the pair/resync monitor will monitor.
1. Open the /etc/services file.
2. Choose the port that the pair/resync monitor will use, and then add the following line to the
services file:
clxmonitor nnnnn /tcp
where nnnnn is the port number. For example:
clxmonitor 22222/udp # CLX Pair/Resync Monitor
clxmonitor 22222/tcp # CLX Pair/Resync Monitor
