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
(remote shell) or
rsh
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.
The 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.
The product installer is the recommended method to license and install the
product. The installer also enables you to configure the product, verify
preinstallation requirements, and view the product's description.
At most points during an installation, you can type b ("back") to return to a
previous section of the installation procedure. The back feature of the
installation scripts is context-sensitive, so it returns to the beginning of a
grouped section of questions. If an installation procedure hangs, use Control–c
to stop and exit the program. There is a short delay before the script exits.
The following sample procedure is based on the installation of a Veritas Storage
Foundation Cluster File System HA cluster with two nodes: "system01" and
"system02." If you are installing on standalone systems only, some steps are
unnecessary, and these are indicated. Default responses are enclosed by
parentheses. Press Return to accept defaults.
Note: If you have obtained a Veritas product from an electronic download site,
the single product download files do not contain the
script, so you must use the product installation script to install the product. For
example, if you download Veritas Cluster File System, use the
script instead of the
installer
(secure shell) utilities as root on all cluster nodes
ssh
script.
