Step 4: Editing the /usr/es/sbin/cluster/etc/exports file

Edit online

Modify the PowerHA® SystemMirror® /usr/es/sbin/cluster/etc/exports file on each node in the cluster to add the IP addresses for the network.

About this task

You can edit the file on one node and copy it to other cluster nodes. You can also use the PowerHA SystemMirror file collection function to keep this file in sync on all of the nodes of the cluster.

To modify the /usr/es/sbin/cluster/etc/exports file on each PowerHA SystemMirror cluster node, edit the /usr/es/sbin/cluster/etc/exports file on the control workstation using the following command:

vi /usr/es/sbin/cluster/etc/exports

For each file system, there should be a line that looks like this:

/fs/fs3big -vers=4,sec=sys:krb5p:krb5i:krb5:dh:none,rw,root=192.168.20.1:19
2.168.20.1:192.168.20.2:192.168.20.3:192.168.21.1:192.168.21.2:192.168.21.
3:192.168.30.1:192.168.30.2:192.168.30.3

Note: To specify the Internet Protocol version 6 address, you can use the -network and -umask options in the /usr/es/sbin/cluster/etc/exports file.

Using this alternative exports file is optional. PowerHA SystemMirror checks the /usr/es/sbin/cluster/etc/exports file when Network File System (NFS) exports a file system or directory. If there is an entry for the file system or directory in this file, PowerHA SystemMirror uses the options listed. However, in some cases, PowerHA SystemMirror might ignore the version option as described in the Administration guide. If the file system or directory that you are trying to export with NSF is not listed in the file or if the alternate file does not exist, the file system or directory is exported with the default option of root access for all cluster nodes.
