Managing Serviceguard Eighteenth Edition, September 2010

IMPORTANT: If you plan to use a Quorum Server, make sure you read the HP

Serviceguard Quorum Server Version A.04.00 Release Notes before you proceed. You can

find them at: www.hp.com/go/hpux-serviceguard-docs -> HP Serviceguard

Quorum Server Software. You should also consult the Quorum Server white papers

at the same location.

A quorum server:

• Can be used with up to 150 clusters, not exceeding 300 nodes total.

• Can support a cluster with any supported number of nodes.

• Can communicate with the cluster on up to two subnets (a primary and an alternate)

using either IPv4 or IPv6 addresses.

Quorum Server Worksheet

You may find it useful to use a Quorum Server worksheet, as in the example that

follows, to identify a quorum server for use with one or more clusters. You may also

want to enter quorum server host and timing parameters on the Cluster Configuration

Worksheet. Blank worksheets are in Blank Planning Worksheets (page 463).

You can use the Quorum Server worksheet to record the following:

Quorum Server Host

The host name (and alternate address, if any) for the

quorum server.

IP Address

The IP address(es) by which the quorum server will

be connected to the cluster.

Supported Node Names

The name (39 characters or fewer) of each cluster node

that will be supported by this quorum server. These

entries will be entered into qs_authfile on the

system that is running the quorum server process.
