Managing Serviceguard 14th Edition, June 2007

Building an HA Cluster Configuration
Creating a Storage Infrastructure with Veritas Cluster File System (CFS)
Chapter 5246
Preparing the Cluster and the System Multi-node
Package
1. First, be 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” on page 257.
4. The Veritas cluster volumes are managed by a Serviceguard-supplied
system multi-node package which runs on all nodes at once, and
cannot failover. In CVM 4.1 and later, which is required for the
Cluster File System, Serviceguard supplies the SG-CFS-pkg
template. (In CVM 3.5, Serviceguard supplies the VxVM-CVM-pkg
template)
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 system multi-node package configuration files, such as
VxVM-CVM-pkg.conf and SG-CFS-pkg.conf. Create and modify
configuration using the cfs admin commands listed in Appendix A.
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:
