Configuring the Cluster

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
Cluster Configuration Template File
When you install Serviceguard for the first time on a node, you do not
have a cluster. Without cluster configuration, however, you cannot have
an Access Control Policy.
You can, however, create a cmclnodelist file to act as a “bootstrap”
monitor access. Bootstrap files are useful if you are doing a rolling
upgrade, so the nodes with older versions can still access the newer
cluster nodes. Monitor access in a bootstrap file also means the node can
appear in Serviceguard Manager; you can see information about it in
Properties, and you can configure it into a cluster after you give the root
password.
To create a bootstrap file:
The cmclnodelist file is not created by default in new installations. If
you create this bootstrap file you should add a comment such as the
following:
###########################################################
# Do Not Edit This File
# This is only a temporary file to bootstrap an unconfigured
# node with Serviceguard version A.11.16
# Once a cluster is created, Serviceguard will not consult
