To install the license, click the Change License File button. Type the

3. Secret Network Key. This password is required. It provides additional
security for network communications among the cluster servers. To
set this key, click the Set Secret Network Key button. You can enter
anything you want for this password, up to 86 characters in length.
NOTE: If more than one HP Clustered File System cluster is running
on the same subnet, be sure that each cluster has a different
Secret Network Key. This step ensures that the multicast traffic
is targeted only at the servers with the same Secret Network
Key.
4. Cluster Administrative Traffic Protocol. Select either multicast or
unicast mode. Multicast mode is recommended; however, if your
network configuration does not allow multicast traffic through the
network, you can use unicast mode.
When you have completed the fields on the General Settings tab, go to the
SAN & Fencing tab.
