Each cluster node must be connected to the public network and each must have a unique host name by which it can be addressed on the public network. The local node from which you install does not have to be part of the cluster.
Provide the following information when installing the SFCFS:
The cluster name, beginning with a letter (a-z, A-Z).
A unique ID from 0-65535 for the cluster. Within the public subnet, a new cluster using a duplicate cluster ID can cause existing clusters to fail.
The Storage Foundation Cluster File System is also supported without I/O fencing enabled. However, without I/O fencing enabled, split brain scenarios can result in data corruption.
The host names of the cluster nodes.
The device names of the network interface cards (NICs) used for the private networks among nodes.
Establishing communication between nodes is required to install Veritas software from a remote system, or to install and configure a cluster. The node from which the installation utility is run must have permissions to run
rsh (remote shell) or
ssh (secure shell) utilities as root on all cluster nodes or remote systems.
See Veritas Storage Foundation and High Availability Solutions Getting Started Guide.
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 scenario.
