HP Serviceguard Version A.11.20 Release Notes, August 2011

improvement is directly dependent on the number of nodes on which the package needs to be
halted; the performance benefit increases as the number of nodes increases. cmhaltpkg (1m)
defaults to this behavior and the feature is automatically enabled once all the nodes in the cluster
are upgraded to Serviceguard A.11.20 April 2011 patch (PHSS_41628) or later.
Support for Veritas 5.1 SP1 on HP-UX 11i v3 Only
IMPORTANT: For information about patches required to support HP Storage Management Suite

Easy Deployment
In the past you had two main choices for configuring a cluster: using Serviceguard commands, as
described in detail in chapter 5 of Managing Serviceguard, or using the Serviceguard Manager
GUI (or some combination of these two methods). As of Serviceguard A.11.20, there is a third
option, called Easy Deployment.
The Easy Deployment tool consists of three commands: cmpreparecl (1m), cmdeploycl
(1m), and cmpreparestg (1m). In addition, there is a new -N option to cmquerycl, which
you can use to obtain networking information for the cluster heartbeat. These commands allow
you to get a cluster up and running in the minimum amount of time. The commands:
• Configure networking and security (cmpreparecl (1m))
• Create and start the cluster with a cluster lock device (cmdeploycl (1m))
• Create and import volume groups as additional shared storage for use by cluster packages
(cmpreparestg (1m)).
See the manpages for more information on the commands.
See also “Cluster-wide Device Special Files (cDSFs)” (page 19).
Advantages of Easy Deployment
• Quick and simple way to create and start a cluster.
• Automates security and networking configuration that must always be done before you configure
nodes into a cluster.
• Simplifies cluster lock configuration.
• Simplifies creation of shared storage for packages.
Limitations of Easy Deployment
• Does not install or verify Serviceguard software.
• Requires agile addressing for disks. See “About Device Special Files (DSFs)” (page 30).
• cmpreparestg (1m) will fail if cDSFs and persistent DSFs are mixed in a volume group.
See “Cluster-wide Device Special Files (cDSFs)” (page 19) for more information about cDSFs.
