4 Configure servers
Before adding a server to a cluster, verify the following:
• The server is connected to the SAN if it will be accessing PSFS filesystems.
• The server is configured as a fully networked host supporting the services to be
monitored. For example, if you want HP Scalable NAS to provide failover protec-
tion for your Web service, the appropriate Web server software must be installed
and configured on the servers.
• If the /etc/hosts file has been modified, it should be consistent with the DNS.
Add a new server to a cluster
Use the following procedures to add a new server (and, optionally, a new Fibre
Channel switch) to an existing cluster.
Add a New Fibre Channel switch
If you are using Fibre Channel switch-based fencing and need to add a new FC
switch for use with the new server, take these steps before adding the server:
1. Shut down HP Scalable NAS on all nodes.
# /etc/init.d/pmxs stop
2. Issue the mxconsole command on one node to start the Management Console.
On the HP Scalable NAS Connect window, specify the server, click Connect,
and select Configure. If you are prompted for a user name and password, specify
the appropriate values.
3. Select the SAN & Fencing tab on the Configure Cluster window and then select
Fibre Channel switch-based fencing. In the SAN Switches section of the tab,
click Add to configure the new switch.
4. Click Apply at the bottom of the Configure Cluster window.
5. Go to the Cluster-Wide Configuration tab, select all servers except the server to
which you are connected, and then click Export To.
