• Standby node: The second node added to the cluster is automatically
designated as the standby node. Should the master node fail, the standby node
replaces it and becomes the master node, and cluster management traffic is
automatically redirected to the new master node.
• Normal nodes: Each additional HP VMA SAN Gateway added to the cluster
is defined as a normal node. During the course of vCLUSTER operation, a
normal node can assume the role of standby or master. There is always only a
single master and at most a single standby node.
All global cluster parameters are defined on the master node and are automatically
inherited by each node added to the cluster. Consequently, the configuration of the
standby node and each subsequent normal node requires only seven steps as
compared to the 25 steps required to configure the master node.
Note that if a global cluster parameter is changed on a node other than the master
node, the changes will only take effect locally until the next time the master node
synchronizes with the rest of the cluster.
To configure a HP VMA SAN Gateway for addition into the vCLUSTER:
1. Connect and log in as admin.
The admin user has no password initially; when the HP VMA SAN Gateway
joins the cluster, the admin role obtains the password that was set on the Master
HP VMA SAN Gateway.
The configuration wizard prompts you to use it for the initial configuration of
the HP VMA SAN Gateway.
2. Reply "No" to Step 1: Configure as master/stand-alone?:
3. Provide values or accept defaults for steps 2 through 7.
Do you want to use the wizard for initial configuration?
