from which the installation utility is run must have permissions to run rsh

■ Symantec recommends configuring the cluster with I/O fencing enabled. I/O
fencing requires shared devices to support SCSI-3 Persistent Reservations
(PR). Enabling I/O fencing prevents data corruption caused by a split brain

The Veritas Storage Foundation Cluster File System is supported without I/O
fencing enabled. However, without I/O fencing enabled, split brain scenarios
can result in data corruption.
