Enter a name or description for this cluster. The cluster name or description appears
on the title bar of the HP Scalable NAS Management Console. The name or
description can contain up to 80 characters. If you will be using a third-party manager,
the name/description will be sent to the manager to help identify the source of SNMP
traps.
License. HP Scalable NAS can be used with either a temporary or a permanent
license. The license is provided in a separate license file. (This file must be present
on the server that you are using to connect to the Console.) To install the license,
click Change License File and then browse to locate the file. The license file is installed
at /etc/opt/hpcfs/licenses/license.
Secret Network Key. This password is required. It provides additional security for
network communications among the cluster servers. To set this key, click Set Secret
Network Key. You can enter anything you want for this password.
Cluster Administrative Traffic Protocol. Select either multicast or unicast mode. Multicast
mode is recommended.
When you have completed the fields on the General Settings tab, go to the SAN &
Fencing tab.
SAN & Fencing tab
When certain problems occur on a server (for example, hardware problems or the
loss of cluster network communications), and the server ceases to effectively coordinate
and communicate with other servers in the cluster, HP Scalable NAS must remove
the server’s access to filesystems to preserve data integrity. This step is called fencing.
The SAN & Fencing tab allows you to select the method that HP Scalable NAS should
use to remove access to the SAN. There are two fencing methods:
• Fibre Channel switch-based fencing. When a server needs to be fenced, HP
Scalable NAS will disable the server’s access in the Fibre Channel fabric. The
server must be rebooted to regain access to the SAN.
• Web management-based fencing. HP Scalable NAS uses remote management
hardware on the server to remove its access to PSFS filesystems.
