Managing Serviceguard 12th Edition, March 2006

Configuring Packages and Their Services
Creating the Package Configuration
Chapter 6272
• 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
CAUTION Serviceguard manages VERITAS processes, specifically gab and LLT,
through system multi-node packages. As a result, the VERITAS
administration commands such as gabconfig, llthosts, and lltconfig
should only be used in the display mode, such as gabconfig -a. You
could crash nodes or the entire cluster if you use VERITAS commands
such as the gab* or llt* commands to configure these components or
affect their runtime behavior.
For CVM, use the cmapplyconf command to add the system multi-node
packages to your cluster. If you are using the VERITAS Cluster File
System, use the cfscluster command to activate and halt the system
multi-node package in your cluster.
NOTE Do not create or modify these packages by editing an ASCII
configuration file. Never edit their control script files.
The CFS admin commands are listed in Appendix A.
Configuring Multi-node Packages
There are two types of multi-node packages that work with the
VERITAS cluster file system: SG-CFS-DG-
id# for disk groups, which you
configure with the cfsdgadm command, and SG-CFS-MP-
id# for mount
points, which you configure with the cfsmntadm command. Each package
name will have a unique number, appended by Serviceguard at creation.
Serviceguard automatically creates each package’s configuration file, its
run and halt scripts, and its control script.
Serviceguard automatically applies the configuration when you enter
cfsdgadm or cfsmntadm..
