Open System Services NFS Management and Operations Guide

OSS NFS server into several servers. For example, if the security requirements of new clients conflict
with those of existing clients, you must assign separate servers to the new clients.
Another situation that calls for server splitting is performance enhancement. If a particular OSS
NFS server is used much more than other OSS NFS servers, it can cause performance problems.
In this case, replace the overused OSS NFS server with multiple OSS NFS servers and allocate the
new servers among clients.
Managing Files
As OSS NFS use increases, you need to address these file maintenance issues:
• “Maintaining the OSS NFS Configuration File”.
• “Backing Up and Restoring Files Using OSS NFS” (page 69).
Maintaining the OSS NFS Configuration File
In the unlikely event that one of the OSS NFS configuration files becomes full and no additional
extents can be allocated, you can rebuild the file by using the File Utility Program (FUP):
CAUTION: To avoid the risk of unpredictable results, this procedure must not be performed while
the OSS NFS subsystem is running.
1. Rename the current OSS NFS configuration file.
2. Create a new file with the name and characteristics of the previous configuration file but with
larger extents.
3. Copy records or use the FUP LOAD command to move records from the previous configuration
file to the new one.
Backing Up and Restoring Files Using OSS NFS
OSS files can be backed up and restored using a combination of the OSS NFS subsystem and
appropriate NFS client software. However, OSS NFS might not restore all file attributes needed
by clients. You should carefully analyze your client requirements to ensure their needs can be met.
Managing Event Messages
Event Management Service (EMS) messages from the OSS NFS manager process, OSS NFS server
processes, and the LAN interface process are routed through the standard system collector process
and can be managed using standard EMS practices. Event message routing is shown in Figure 6,
and the event messages are described in the Operator Messages Manual.
