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 429).

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.

LVM Planning

You can create storage groups using the HP-UX Logical Volume Manager (LVM), or

using Veritas VxVM and CVM software as described in the next section.

When designing your disk layout using LVM, you should consider the following:

• The root disk should belong to its own volume group.

• The volume groups that contain high availability applications, services, or data

must be on a bus or busses available to the primary node and all adoptive nodes.

• High availability applications, services, and data should be placed in a separate

volume group from non-high availability applications, services, and data.
