9.Check the configuration using the cmcheckconf -Ppkgname.config, then apply the Serviceguard configuration using the cmapplyconf -Ppkgname.config command or SAM.

10.Distribute Metrocluster/Continuous Access configuration, environment and control script files to other nodes in the cluster by using ftp, rcp or scp:

# rcp -p /etc/cmcluster/pkgname/* \

other_node:/etc/cmcluster/pkgname

See the example script Samples/ftpit to see how to semi-automate the copy using ftp. This script assumes the package directories already exist on all nodes.

Using ftp may be preferable at your organization, since it does not require the use of a.rhosts file for root. Root access via the .rhosts may create a security issue.

11.Verify that each node in the Serviceguard cluster has the following files in the directory

/etc/cmcluster/pkgname.

pkgname.cntl

Seviceguard package control script

pkgname_xpca.env

Metrocluster/Continuous Access environment file

pkgname.config

Serviceguard package ASCII configuration file

pkgname.sh

Package monitor shell script, if applicable

other files

Any other scripts you use to manage Serviceguard packages

The Serviceguard cluster is ready to automatically switch packages to nodes in remote data centers using Metrocluster/Continuous Access.

Configuring Modular Packages

With HP Serviceguard A.11.18 and above, Modular packages can be created using building blocks that consist of only those functions that are required for the package. This new modular method of creating packages provides the following benefits:

•All package parameters are now configured in one place - the package configuration file.

•Separate package control files need not be created and distributed in the cluster.

Modular Metrocluster packages can be created using Metrocluster with Continuous Access for XP A.09.00 and above. Legacy Metrocluster packages can also be migrated to Modular packages.

This section discusses the following topics:

•“Configuring Modular Packages with Metrocluster with Continuous Access XP A.09.00” (page 181)

•“Migrating Legacy Packages to Modular Packages with Metrocluster with Continuous Access XP A.09.00” (page 184)

•“Configuring Modular Packages with Metrocluster with Continuous Access XP A.10.00 or Later” (page 185)

•“Migrating Legacy Packages to Modular Packages using Metrocluster with Continuous Access XP A.10.00 or Later” (page 186)

•“Upgrading Metrocluster XPCA Modular Packages to the Latest Version” (page 187)

Configuring Modular Packages with Metrocluster with Continuous Access XP A.09.00

Modular packages can be created using Metrocluster with Continuous Access XP A.09.00.

Complete the following steps to configure a Modular package using Metrocluster with Continuous Access and XP A.09.00.
