IS392 Installation Step:

Check chapter 2 for more automounter details.

In this environment the automounter (autofs) version 4 is required for

mounting NFS file systems. Check the installed version with:

lsmod | grep autofs

autofs4 60040 1

If “autofs4” is not listed, install the corresponding rpm. For example:

rpm -Uv autofs4-4.1.3-1.8.ia64.rpm

Uncomment the following line in /etc/modprobe.conf:

alias autofs autofs4

Then reload the autofs4 kernel module using

modprobe autofs4

Restart the automounter process with command

/etc/init.d/autofs start

Also check that the automounter is configured as part of the system

startup. Commands for checking are:

/sbin/chkconfig -l autofs

and for adding autofs to runlevel 3 and 5:

/sbin/chkconfig autofs 35

IS393 Installation Step:

Add the following entry to your /etc/auto.master file:

/import /etc/auto.import nfsvers=3

The use of NFS version 3 is required.
