Managing Serviceguard NFS for Linux, September 2006

Installing and Configuring Serviceguard NFS for Linux
Before Creating an Serviceguard NFS Package
Chapter 224
6. Create an entry for the name of the package in the DNS or NIS name
resolution files, or in /etc/hosts, so that users will mount the
exported file systems from the correct node. This entry maps the
package name to the package’s relocatable IP address.
7. Decide whether to place executables locally on each client or on the
NFS server. There are a number of trade-offs to be aware of
regarding the location of executables with Serviceguard NFS.
The advantages of keeping executables local to each client are as
follows:
• No failover time. If the executables are local to the client, there is
no delay if the NFS server fails.
• Faster access to the executables than accessing them through the
network.
The advantage of putting the executables on the NFS server is as
follows:
• Ease of management. If the executables are located in one
centralized location, the administrator must update only one
copy when changes are made.
