Making a connection through a switched-fabric topology

Edit the /etc/failover.conf file to add primary and secondary paths to the storage unit LUNs. "Confirming storage connectivity for SGI in a switched-fabric topology" describes the paths of the character-special files. These files begin with the worldwide node name of the storage unit. Figure 1 shows an example of an edited /etc/failover.conf file.

Use the IRIX /sbin/scsifo -d command to confirm the failover configuration.
