Managing HP Serviceguard for Linux, Tenth Edition, September 2012

• If your package will use relocatable IP addresses, enter the ip_subnet and
ip_address addresses. See the parameter descriptions (page 214) for rules and
restrictions.
In a cross-subnet configuration, configure the additional ip_subnet_node
parameter for each ip_subnet as necessary; see “About Cross-Subnet Failover”
(page 151) for more information.
• For each service the package will run:
◦ enter the service_name (for example, a daemon or long-running process)
◦ enter the service_cmd (for example, the command that starts the process)
◦ enter values for service_fail_fast_enabled and
service_halt_timeout if you need to change them from their defaults.
◦ service_restart if you want the package to restart the service if it exits. (A
value of unlimited can be useful if you want the service to execute in a loop,
rather than exit and halt the package.)
Include a service entry for disk monitoring if the package depends on monitored
disks. Use entries similar to the following:
service_name=“cmresserviced_Pkg1”
service_cmd=”$SGBIN/cmresserviced /dev/sdd1”
service_restart=””
See “Creating a Disk Monitor Configuration” (page 231) for more information.
• If the package needs to activate LVM volume groups, configure vgchange_cmd,
or leave the default.
• If the package needs to mount LVM volumes to file systems (other than Red Hat GFS;
see fs_type (page 222)), use the vg parameters to specify the names of the volume
groups to be activated, and select the appropriate vgchange_cmd.
Use the fs_ parameters (page 221) to specify the characteristics of file systems and
how and where to mount them. See the comments in the FILESYSTEMS section of
the configuration file for more information and examples.
Enter each volume group on a separate line, for example:
vg vg01
vg vg02
