Disable a Server for Maintenance
If you need to perform maintenance (such as an application software
upgrade) on a server that is providing the primary interface for a virtual
host, take these steps before working on the server:
1. Disable the server. (Choose the server from the Servers window on the
HP CFS Management Console, right-click, and select Disable.) This
step causes the virtual host to fail over to a backup network interface
on another server.
2. If you want the virtual host to remain on the backup network interface
after the original server is returned to operation but the virtual host is
using
AUTOFAILBACK as its failback policy, make that network
interface the primary network interface. (Choose the virtual host from
the Virtual Hosts window, right-click, and select Properties.)
3. Perform the necessary maintenance on the original server and then
reenable it.
Troubleshoot Cluster Problems
HP Clustered File System Fails to Start
If the HP Clustered File System service fails to start on a server, check that
the domain name of the server is configured in the DNS suffix list. The
DNS suffix list is configurable via the Advanced TCP/IP Properties.
