• “Managing Disk Groups and Mount Points Using Legacy Packages” (page 221)
NOTE: The “Creating the Storage Infrastructure with Veritas Cluster Volume Manager (CVM)”
(page 224) 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 132), 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
