Managing HP Serviceguard for Linux, Tenth Edition, September 2012

1. In the cluster configuration file, modify the value of CLUSTER_LOCK_LUN for each
node.
2. Run cmcheckconf to check the configuration.
3. Run cmapplyconf to apply the configuration.
If you need to replace the physical device, see “Replacing a Lock LUN” (page 291).
Changing MAX_CONFIGURED_PACKAGES
As of Serviceguard A.11.18, you can change MAX_CONFIGURED_PACKAGES while the
cluster is running. The default for MAX_CONFIGURED_PACKAGES is the maximum number
allowed in the cluster. You can use Serviceguard Manager to change
MAX_CONFIGURED_PACKAGES, or Serviceguard commands as shown below.
Use the cmgetconf command to obtain a current copy of the cluster's existing
configuration, for example:
cmgetconf -C <cluster_name> clconfig.conf
Edit the clconfig.conf file to include the new value for
MAX_CONFIGURED_PACKAGES. Then use the cmcheckconf command to verify the
new configuration. Using the -k or -K option can significantly reduce the response time.
Use the cmapplyconf command to apply the changes to the configuration and send
the new configuration file to all cluster nodes. Using -k or -K can significantly reduce
the response time.
Configuring a Legacy Package
IMPORTANT: You can still create a new legacy package. If you are using a
Serviceguard Toolkit such as Serviceguard NFS Toolkit, consult the documentation for
that product.
Otherwise, use this section to maintain and re-work existing legacy packages rather than
to create new ones. The method described in Chapter 6: “Configuring Packages and
Their Services ” (page 199), is simpler and more efficient for creating new packages,
allowing packages to be built from smaller modules, and eliminating the separate package
control script and the need to distribute it manually.
If you decide to convert a legacy package to a modular package, see “Migrating a
Legacy Package to a Modular Package” (page 281). Do not attempt to convert
Serviceguard Toolkit packages.
Creating or modifying a legacy package requires the following broad steps:
1. Generate the package configuration file
2. Edit the package configuration file
3. Generate the package control script
4. Edit the package control script
