4 Migration of Serviceguard NFS Legacy Package to
Serviceguard NFS Modular Package
This chapter explains how to migrate from the current Serviceguard NFS Legacy package to the
new Serviceguard NFS Modular package.
The migration of the Legacy packages to the Modular package configuration is done using the
cmmigratepkg command. The cmmigratepkg command automates the migration of a legacy
package to a modular package for standard Serviceguard module parameters. The NFS module
parameters need to be manually configured in the modular package. The syntax of cmmigratepkg
command is as follows:
cmmigratepkg –p <package_name> [-x<external_script_name>] -o <output_file>
The package must be a configured legacy package and should be brought to offline state before
starting the migration. The cmmigratepkg command reads control script of the package.
Therefore, the control script must be located on the node where the command is run.
For detailed information on migrating packages from legacy to modular style, see the Migrating
Packages from Legacy to Modular Style at http://docs.hp.com/en/ha.html
Migrating a sample legacy package with control script
This section explains about migrating a sample legacy package (pkg01) with control script
(nfs1.cntl) and configuration file (nfs1.conf) located in /etc/cmcluster/nfs directory
to the modular style. The NFS specific control scripts for this example are hanfs.1.sh, nfs1.mon
and nfs1.flm.
Perform the following steps to migrate the Legacy package to Modular package configuration.
1. The package must be a configured legacy package and should be brought to offline state
using cmhaltpkg command.
cmhaltpkg pkg01
2. Enter the directory where the legacy NFS package configuration file (.conf) and the control
script (.cntl) to be migrated are stored.
cd /etc/cmcluster/nfs
Create another directory to hold the contents of the migrated files and set the permission to
744.
mkdir /etc/cmcluster/nfs/modular
chmod 744 /etc/cmcluster/nfs/modular
3. Comment the HA_NFS_SCRIPT_EXTENSION variable definition in the package control
script. The following line must be commented in the nfs1.cntl file.
# HA_NFS_SCRIPT_EXTENSION = "1.sh"
4. Comment the service specific parameter definitions in the package configuration file. The
following lines must be commented in the nfs1.conf file.
# SERVICE_NAME nfs1.monitor
# SERVICE_FAIL_FAST_ENABLED NO
# SERVICE_HALT_TIMEOUT 300
5. Run cmapplyconf command to apply the above two configuration changes to the legacy
package.
cmapplyconf -P /etc/cmcluster/nfs/nfs1.conf
Modify the package configuration ([y]/n)? y
