The hardware configuration is a basic two-node IRIX FailSafe configuration:
Two nodes
A set of shared disks
One public NIC on each node, connected to the Corporate LAN
One private NIC on each node, connected directly, using a cross-over cable, to the NIC of the other node
One serial line connected directly to the other node’s system controller
The following is a sample configuration for a primary companion named spinnaker and a secondary companion named mizzen. For information about this configuration, consult your SGI documentation.

You can configure IRIX FailSafe using either a GUI (with
the fstask utility) or the command line (using
the cluster_mgr utility). Examples for
both methods are included for each step.For more information about
the command-line arguments, see your SGI documentation.
SGI provides unsupported, template command line files. Although these files are not supported by either SGI or Sybase, they have been used and tested within our Engineering organization. You can download these files from:
www.sybase.com/detail?id=1022631
In the examples below, when the command line argument
is called for, it is assumed that the corresponding script has been
previously been edited to reflect your environment.
The following list provides a high-level overview of the steps required to setup IRIX FailSafe. The details of each action are listed in the subsequent sections:
Install the FailSafe scripts
Start FailSafe Configuration Tool
Define the primary and secondary nodes
Define the failover policies for the primary and secondary nodes
Define the cluster
Define the logical volume resources for the primary and secondary nodes
Define the failsafe resources for the primary and secondary nodes
Define the Adaptive Server resources for the primary and secondary nodes
Define the resource groups for the primary and secondary nodes
Start the high availability Services
Bring the resource groups online
