Do NFS export from AIX HACMP CLUSTER to Linux server

Scenario: Export /hacmp/export from aixhanode1 to linux host linuxnode1 and linuxnode2

On PowerHA-cluster /usr/es/sbin/cluster/etc/exports is used for exporting filesystems.

Step 1: For Cluster setup while doing NFS export from Cluster node edit file /usr/es/sbin/cluster/etc/exports . Don’t use /etc/exports file, /etc/exports file used in NON-CLUSTER environment.
Step 2:
Find export directory stanza and add hostname to whom directory need to export.
Here find stanza "/hacmp/export" and add client name at last without affecting current hostname list.
Find stanza for /hacmp/export in file /usr/es/sbin/cluster/etc/exports and add hostname linuxnode1 linuxnode2 and save file
Vi /usr/es/sbin/cluster/etc/exports
/hacmp/export -rw,root=linuxnode1:linuxnode2
Execute following command to activate changes which we made in file /usr/es/sbin/cluster/etc/exports , by executing following command.
exportfs -a -f /usr/es/sbin/cluster/etc/exports
Step 4 :
Check on both client whether NFS directory is exported or not by using below command
showmount -e nfsservername
showmount –e aixhanode1
Step 5:
Mount share directory using mount command.
Mount aixhanode1:/hacmp/export /mnt      //mounting on temp mount point
Mount aixhanode1:/hacmp/export /mnt
       Or you also mount on same name mount point using below command.
Before executing make sure that /hacmp/export exist on both NFS client.
Mount aixhanode1:/hacmp/export  /hacmp/export
Mount aixhanode1:/hacmp/export  /hacmp/export

Verify whether directory/FS is mounted or not by executing below command.
df –hT /hacmp/export
