HP Serviceguard Extended Distance Cluster for Linux A.11.20.10 Deployment Guide, December 2012

IMPORTANT: It is recommended that you maintain an equal number of nodes at both sites during
maintenance.
Configuring the RAID Monitoring Service
By default, RAID monitoring service is available as part of the package configuration file. If you
need to configure more than one serviceguard-xdc package running in the same cluster, edit the
service_name field as service_name. It must be unique for all the packages running on same
Serviceguard cluster.
NOTE: Before applying the package configuration, check cat/proc/mdstat output to ensure
that the MD device that you have specified in the package configuration, is not active. If active,
then stop the MD device as described in step 2, Creating a serviceguard-xdc Modular Package.
