Veritas Storage Foundation 5.1 SP1 Cluster File System Installation Guide (5900-1510, April 2011)

With server-based fencing, you can have the coordination points in your

configuration as follows:

■ Combination of CP servers and SCSI-3 compliant coordinator disks

■ CP servers only

Symantec also supports server-based fencing with a single highly available

CP server that acts as a single coordination point.

See “About planning to configure I/O fencing” on page 88.

See “Recommended CP server configurations” on page 93.

This section covers the following example procedures:

See “To configure server-based fencing for the Storage

Foundation Cluster File System cluster (one CP server and

two coordinator disks)” on page 160.

Mix of CP servers and

coordinator disks

See “To configure server-based fencing for the Storage

Foundation Cluster File System cluster (single CP server)”

on page 165.

Single CP server

To configure server-based fencing for the Storage Foundation Cluster File System

cluster (one CP server and two coordinator disks)

Depending on the server-based configuration model in your setup, make sure

of the following:

■ CP servers are configured and are reachable from the Storage Foundation

Cluster File System cluster. The Storage Foundation Cluster File System

cluster is also referred to as the application cluster or the client cluster.

See “Setting up the CP server” on page 96.

■ The coordination disks are verified for SCSI3-PR compliance.

See “Checking shared disks for I/O fencing” on page 151.

Start the installsfcfs with -fencing option.

# /opt/VRTS/install/installsfcfs -fencing

The installsfcfs starts with a copyright message and verifies the cluster

information.

Note the location of log files which you can access in the event of any problem

with the configuration process.
