Serviceguard for Linux Version A.11.16 Release Notes
Compatibility Information and Installation Requirements
Chapter 1 45
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.
Preventing Boot-Time vgscan and Ensuring Serviceguard
Volume Groups Are Deactivated
By default, Linux will perform LVM startup actions whenever the
system is rebooted. These include a vgscan (on some Linux distributions)
and volume group activation. This can cause problems for volumes used
in a Serviceguard environment (for example, a volume group for a
Serviceguard package that is not currently running may be activated). To
prevent such problems, proceed as follows on the various Linux versions.
SUSE Linux Enterprise Server
Prevent a vgscan command at boot time by removing the
/etc/rc.d/boot.d/S07boot.lvm file from all cluster nodes.
NOTE Be careful if you use YAST or YAST2 to configure volume groups, as that
may cause all volume groups to be activated. After running YAST or
YAST2, check that volume groups for Serviceguard packages not
currently running have not been activated, and use LVM commands to
deactivate any that have. For example, use the command vgchange -a n
/dev/sgvg00 to deactivate the volume group sgvg00.
Red Hat 3
After creating volume groups on a node, back them up using
vgcfgbackup, then comment out the following lines in the
/etc/rc.d/rc.sysinit file (there are two places in this file where you
need to comment them out):
