Cluster and Package Maintenance
Configuring a Legacy Package
Chapter 7 267
Customizing the Package Control Script
Check the definitions and declarations at the beginning of the control
script using the information in the Package Configuration worksheet.
You need to customize as follows; see the relevant entries under “Package
Parameter Explanations” on page 201 for more discussion.
• Update the PATH statement to reflect any required paths needed to
start your services.
• Specify the Remote Data Replication Method, Software RAID Data
Replication method, and MD RAID configuration file if necessary.
CAUTION Follow the directions in the control script carefully; see “Excerpt from
Legacy Package Control Script: Remote Data Replication, Software
RAID Data Replication and MD RAID Sections” on page 268.
• 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 (ext2 is the default; ext3, reiserfs, or
gfs can also be used; see the fs_ parameters staring on page 212 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 may be used.
• Add service name(s).
• Add service command(s)
• Add a service restart parameter, if you so decide.
For more information about services, see the discussion of the
service_ parameters that starts on page 209.
