Managing HP Serviceguard for Linux, Tenth Edition, September 2012

For security reasons, the control script must reside in a directory with the string
cmcluster in the path. The control script is placed in the package directory and is
given the same name as specified in the RUN_SCRIPT and HALT_SCRIPT parameters
in the package configuration file. The package control script template contains both the
run instructions and the halt instructions for the package. You can use a single script for
both run and halt operations, or, if you wish, you can create separate scripts.
Use cmmakepkg to create the control script, then edit the control script. Use the following
procedure to create the template for the sample failover package pkg1.
First, generate a control script template, for example:
cmmakepkg -s $SGCONF/pkg1/pkg1.sh
Next, customize the script; see “Customizing the Package Control Script ”.
Customizing the Package Control Script
You need to customize as follows; see the relevant entries under “Package Parameter
Explanations” (page 205) for more discussion.
• Update the PATH statement to reflect any required paths needed to start your services.
• Specify the Remote Data Replication Method and Software RAID Data Replication
method if necessary.
CAUTION: If you are not using the XDC or CLX products, do not modify the REMOTE
DATA REPLICATION DEFINITION section. If you are using one of these products,
consult the product’s documentation.
• If you are using LVM, enter the names of volume groups to be activated using the
VG[] array parameters, and select the appropriate options for the storage activation
command, including options for mounting and unmounting file systems, if necessary.
Specify the file system type (ext2is the default; ext3, reiserfs, or gfs can also
be used; see the fs_ parameter descriptions starting with fs_mount_retry_count
(page 221) for more information).
• Add the names of logical volumes and the file system that will be mounted on them.
• Specify the filesystem mount and unmount retry options.
• If your package uses a large number of volume groups or disk groups or mounts a
large number of file systems, consider increasing the number of concurrent
vgchange, mount/umount, and fsck operations;
• Define IP subnet and IP address pairs for your package. IPv4 or IPv6 addresses are
allowed.
• Add service name(s).
