3.7.0 HP StorageWorks HP Scalable NAS File Serving Software administration guide - HP Scalable NAS 3.7 for Linux (AG513-96002, October 2009)

• 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 host.
Also note the following:
• After creating virtual hosts, you will need to configure your applications to recog-
nize them.
• As of the 3.5.1 release, HP Scalable NAS no longer uses the old aliases interface
but instead uses the NETLINK facility to configure virtual hosts as secondary ad-
dresses. As a result, ipconfig(8) should no longer be used to query for HP
Scalable NAS virtual hosts. Instead, use ip(8) for the queries. For example, ip
addr show displays the virtual hosts.
Add or modify a virtual host
To add or update a virtual host, select the appropriate option:
• To add a new virtual host, select Cluster > Add > Add Virtual Host or click the
V-Host icon on the toolbar. Then configure the virtual host on the Add Virtual Host
window.
• To update an existing virtual host, select that virtual host on either the Server or
Virtual Hosts window, right-click, and select Properties. Then make your changes
on the Virtual Host Properties window.
