HP Serviceguard manual Building an HA Cluster Configuration

NOTE: You can also accomplish this by running cmpreparecl; cmdeploycl calls cmpreparecl.

For more information, see “Configuring Root-Level Access” (page 166) and “Configuring Name Resolution” (page 168). Those sections describe the “manual” (HP-UXcommand-line) method of accomplishing what cmpreparecl does.

•Configures a two-node cluster (cluster1).

•Configures the LVM volume group and physical volume for the lock disk.

•Starts the cluster on ftsys9 and ftsys10.

NOTE: The cluster does not yet have shared storage for packages.

Other forms of cmdeploycl allow you to create the cluster with a quorum server or lock LUN instead of a lock disk; see the manpage for more information.

If you use a quorum server, the quorum server software must already be installed and configured on the quorum server; see the latest version of the HP Serviceguard Quorum Server Version A.04.00 Release Notes, at http://www.hp.com/go/hpux-serviceguard-docs under HP Serviceguard Quorum Server Software. cmdeploycl requires an IPv4 address (or addresses) for the quorum server; to configure IPv6 addresses, see “Specifying a Quorum Server” (page 190).

If shared storage already exists on both nodes, and you use cmdeploycl without any -Loption, cmdeploycl will create an LVM lock disk using the shared storage.

See cmdeploycl (1m) for more information.
