Linux Distribution Differences for Serviceguard
The SUSE Linux Enterprise Server distribution of HP Serviceguard differs from the
Red Hat distributions in a few details, which are described below.
File Locations
Serviceguard uses a special file, cmcluster.conf, to define the locations for
configuration and log files within the Linux file system. The different distributions use
different locations. See “Understanding the Location of Serviceguard Files” in Chapter
5 of Managing HP Serviceguard for Linux for more information.
Ensuring Clean Shutdown of Cluster Nodes Running SUSE SLES10
To ensure that the cluster nodes halt correctly when they are shut down, edit the file
/etc/sysconfig/boot on each node and change the value of the RUN_PARALLEL
parameter from yes to no.
Implementing Channel Bonding in SUSE Linux Enterprise Server
Channel bonding implementation differs between SUSE Linux Enterprise Server and
the Red Hat distributions. Procedures for both are in Chapter 5 of Managing HP
Serviceguard for Linux, which is included on the same CD as your HP Serviceguard for
Linux software.
