Managing Serviceguard Nineteenth Edition, Reprinted June 2011

NOTE: The “Creating the Storage Infrastructure with Veritas Cluster Volume Manager (CVM)”
(page 208) section explains how to configure Veritas Cluster Volume Manager (CVM) disk groups
without CFS; that is, for raw access only. Both solutions use many of the same commands, but in
a slightly different order.
Refer to the Serviceguard man pages for more information about the commands cfscluster,
cfsdgadm, cfsmntadm, cfsmount, cfsumount, and cmgetpkgenv. Information is also in
the documentation for HP Serviceguard Storage Management Suite posted at http://www.hp.com/
go/hpux-serviceguard-docs.
IMPORTANT: Before you proceed, make sure you have read “Planning Veritas Cluster Volume
Manager (CVM) and Cluster File System (CFS)” (page 121), which contains important information
and cautions.
Preparing the Cluster and the System Multi-node Package
The Veritas cluster volumes are managed by a Serviceguard-supplied system multi-node package,
SG-CFS-pkg, which runs on all nodes at once, and cannot fail over.
The package for CVM 4.1 and later has the following responsibilities:
• Maintain Veritas configuration files /etc/llttab, /etc/llthosts, /etc/gabtab
• Launch required services: cmvxd, cmvxpingd, vxfsckd
• Start/halt Veritas processes in the proper order: llt, gab, vxfen, odm, cvm, cfs
NOTE: Do not edit the configuration file SG-CFS-pkg.conf. Create and modify configuration
using the cfs administration commands.
1. First, make sure the cluster is running:
cmviewcl
2. If it is not, start it:
cmruncl
3. If you have not initialized your disk groups, or if you have an old install that needs to be
re-initialized, use the vxinstall command to initialize VxVM/CVM disk groups. See
“Initializing the Veritas Volume Manager ” (page 209).
4. Activate the SG-CFS-pkg and start up CVM with the cfscluster command; this creates
SG-CFS-pkg, and also starts it.
This example, for the cluster file system, uses a timeout of 900 seconds; if your CFS cluster
has many disk groups and/or disk LUNs visible to the cluster nodes, you may need to a longer
timeout value. Use the -s option to start the CVM package in shared mode:
cfscluster config -t 900 -s
5. Verify the system multi-node package is running and CVM is up, using the cmviewcl or
cfscluster command. Following is an example of using the cfscluster command. In
the last line, you can see that CVM is up, and that the mount point is not yet configured:
cfscluster status
Node : ftsys9
Cluster Manager : up
CVM state : up (MASTER)
MOUNT POINT TYPE SHARED VOLUME DISK GROUP STATUS
Node : ftsys10
Cluster Manager : up
CVM state : up
MOUNT POINT TYPE SHARED VOLUME DISK GROUP STATUS
