Managing Serviceguard Eighteenth Edition, September 2010

Displaying the cDSF Configuration
• To see the members of a cDSF group, log in on one of the members and run
cmsetdsfgroup -q
• To display all the information about the configuration stored in the configuration
file /etc/cmcluster/cdsf/cdsf_config, log in on one of the cDSF group
members and run cmsetdsfgroup -v -q
CAUTION: Do not modify cdsf_config.
• To report information (in line output format only) about DSFs, cDSFs, and volume
groups for one or more nodes, use cmquerystg (1m).
• You can also use the HP-UX command io_cdsf_config (1m) to display
information about cDSFs.
See the manpages for more information.
Migrating Existing LVM Cluster Storage to cDSFs
You can migrate existing LVM cluster storage to cDSFs using the HP-UX command
vgcdsf (1m). See the manpage for more information. See also “LVM Commands
and cDSFs” (page 137).
IMPORTANT: If you change the cluster lock volume or volumes to cDSFs, you need
to change the cluster lock information in the cluster configuration file and re-apply the
configuration; follow one of the procedures under “Updating the Cluster Lock
Configuration” (page 364).
Using Easy Deployment
Easy Deployment commands enable you to get a cluster up and running in the minimum
amount of time. Instructions follow. For an overview, see “About Easy Deployment”
(page 137).
Before You Start
IMPORTANT: Before you start, you should have done the planning and preparation
outlined in Chapter 4 (page 121). You must also do the following.
• Install Serviceguard on each node that is to be configured into the cluster; see
“Installing and Updating Serviceguard ” (page 205).
You must have superuser capability on each node.
• Make sure all the nodes have access to at least one fully configured network.
