the active servers and they will not be able to absorb the workload from another

Guidelines for creating Virtual NFS Services
When creating Virtual NFS Services, follow these guidelines:
• When planning the Virtual NFS Services needed for your cluster, first determine
the network services that will be available to your clients. Then determine the IP
addresses for those services. You will need to create a Virtual NFS Service for
each IP address.
• Choose hostnames that differ from your actual server names. Virtual NFS Services
are independent of specific servers, and their names should be independent as
well.
• Use an IP address that is on the same subnet as the network interfaces where it
will be configured.
• Update the DNS name service or the /etc/hosts file with the virtual hostnames
and IP addresses. (For improved performance, the Management Console caches
hostname lookups. If your DNS changes, you may need to restart the console so
that it will reflect the new hostname.)
• Do not use ifconfig or another tool to configure the IP address in the operating
system or a system startup script. HP Scalable NAS configures the operating
system appropriately to support the Virtual NFS Service.
• Virtual NFS Services share a common name-space with other HP Scalable NAS
virtual hosts. You cannot create a virtual host and a Virtual NFS Service having
the same network address.
• After creating Virtual NFS Services, you will need to configure your applications
to recognize them.
Add a Virtual NFS Service
To add a virtual NFS Service, select Cluster > Add > Add Virtual NFS Service.
