Using Easy Deployment in Serviceguard and Metrocluster environments on HP-UX 11i v3 - (March 2012)

Cluster Easy Deployment command-line support

Easy Deployment of a Serviceguard cluster and easy creation of clustered LVM, VxVM/CVM storage is supported

using the cmdeploycl and cmpreparestg commands, respectively.

The functions performed by these Easy Deployment commands are:

• cmpreparestg:

– Creates LVM volume groups

– Creates LVM logical volumes

– Creates file systems on LVM logical volumes

– Configures mount points for LVM logical volumes

– Distributes (imports) LVM configuration across nodes

– Creates and modifies a VxVM/CVM disk group

– Creates file systems on VxVM/CVM disk groups

– Configures mount points for VxVM/CVM disk groups

• cmdeploycl

– Runs cmpreparecl on all prospective cluster nodes

– Applies the network configuration specified by ”net_template” using cmapplyconf –N

– Creates storage for use as a cluster lock using cmpreparestg (if the –b option is specified)

– Creates a cluster with the name specified by ”cluster_name” (or <localhost>_name, default)

– Runs the cluster

For more information on command-line support for cluster Easy Deployment, refer to the “About Easy Deployment”

and “Using Easy Deployment” sections in Managing Serviceguard Nineteenth Edition, available at

www.hp.com/go/hpux-serviceguard-docs -> HP Serviceguard. You can also refer to the command man pages

cmdeploycl (1m) and cmpreparestg (1m) for more details.

Note:

There is no equivalent functionality to the cmpreparestg command in

Serviceguard Manager.

Limitations

• Easy Deployment of extended distance clusters is currently not supported both via the Serviceguard command line

and Serviceguard Manager.

• The network configuration performed as part of cluster Easy Deployment does not support cross-subnet

configurations. However, users can still easy-deploy a cluster from Serviceguard Manager with a cross-subnet

configuration if they skip the network configuration step in the Easy Deploy workflow and perform the network

configuration manually. Users can also use the “Create Cluster” option for performing cross-subnet configurations.
