Building an HA Cluster Configuration
Configuring the Cluster
Chapter 5180
For more details, see the cmquerycl(1m) man page.
The man page for the cmquerycl command lists the definitions of all the
parameters that appear in this file. Many are also described in
Chapter 4, “Planning and Documenting an HA Cluster,” on page 89.
Modify your $SGCONF/clust1.config file to your requirements, using
the data on the cluster configuration worksheet. In the file, keywords are
separated from definitions by white space. Comments are permitted, and
must be preceded by a pound sign (#) in the far left column. See the
manpage for the cmquerycl command for more details.
Specifying a Quorum Server
If you will be using a quorum server, be sure to specify the -q qshost
option with the cmquerycl command. For example on a Red Hat
distribution:
cmquerycl -v -n lp001 -n lp002 -q lp-qs \
-C $SGCONF/lpcluster.config
Specifying a Lock LUN
If you will be using a lock LUN, be sure to specify the -L
lock_lun_device option with the cmquerycl command. If the name of
the device is the same on all nodes, enter the option before the node
names, as in the following example:
cmquerycl -v -L /dev/cciss/c0d0p1 -n lp01 -n lp02 \
-C $SGCONF/lpcluster.config
If the name of the device is different on the different nodes, use the
option to specific each device file following each node name, as in the
following example:
cmquerycl -v -n lp01 -L /dev/cciss/c0d0p1 \
-n lp02 -L /dev/cciss/c0d0p2 \
-C $SGCONF/lpcluster.config
