Customizing Packages for CVM
NOTE Check the Serviceguard, SGeRAC, and SMS Compatibility and Feature
Matrix and the latest Release Notes for your version of Serviceguard for
up-to-date information about support for CVM and CFS:

After creating the CVM disk group, you need to customize the
Serviceguard package that will access the storage. Use the following
procedure to modify a legacy package to use Cluster Volume Manager
(CVM) disk groups. If you are using the Veritas Volume Manager
(VxVM), use the procedure in the previous section. If you decide to create
a new package, see Chapter 6, “Configuring Packages and Their
Services,” on page 275.
1. Rename the old package control script as follows:
# mv Package.ctl Package.ctl.bak
2. Create a new package control script with the same name as the old
one:
# cmmakepkg -s Package.ctl
3. Edit the new script to include the names of the new CVM disk groups
and logical volumes.
The new portions of the package control script that are needed for
CVM use are as follows:
•The CVM_DG[] array. This defines the CVM disk groups that are
used for this package. The first CVM_DG[] entry should be in
index 0, the second in 1, etc. For example:
CVM_DG[0]="dg01"
CVM_DG[1]="dg02"
•The LV[], FS[] and FS_MOUNT_OPT[] arrays are used the same
as they are for LVM. LV[] defines the logical volumes, FS[]
defines the mount points, and FS_MOUNT_OPT[] defines any
mount options.
