HACMP file system export from AIX server

Hello everyone today i am going to share how to export AIX HACMP File system and issues i faced while doing export of that File system from AIX to Linux client.

There 2 ways for exporting File system from AIX HACMP cluster node to Linux Clinet.

1. Edit   /usr/es/sbin/cluster/etc/exports and Activate changes by using following command.
#exportfs -a -f /usr/es/sbin/cluster/etc/exports

2. Use smitty nfs to export File system .

#smitty nfs 
Network File System (NFS)
Change / Show Attributes of an Exported Directory
Pathname of exported directory                     [/oracle/log] 
* Version of exported directory to be changed        [3] 

Then following screen will appear where AIX admin need to enter Exported FS name amd also 
Client details to whom this File system need to export . Important part is specify path name of alternate export file and that path is like below 
Pathname of alternate exports file                 [ /usr/es/sbin/cluster/etc/exports]   // This is for AIX hacmp server for non-hacmp export file name is /etc/exports

At final smitty window enter value like below:

Type or select values in entry fields.
Press Enter AFTER making all desired changes.

[TOP]                                                   [Entry Fields]
* Pathname of directory to export                     /oracle/log
* Version of exported directory to be changed         3
  Anonymous UID                                      [-2]
  Public filesystem?                                 [no]                                                                             +
* Change export now, system restart or both           both                                                                            +
  Pathname of alternate exports file                 [ /usr/es/sbin/cluster/etc/exports]
  Allow access by NFS versions                       [3]
  External name of directory (NFS V4 access only)    []
  Referral locations (NFS V4 access only)            []
  Replica locations                                  []
  Ensure primary hostname in replica list             yes                                                                             +
  Allow delegation?                                  []
  Scatter                                             none                                                                            +
  Security method 1                                  [sys]                                                                            +
      Mode to export directory                       [read-write]                                                                     +
      Hostname list. If exported read-mostly         []
      Hosts & netgroups allowed client access        [linuxclient]

      Hosts allowed root access                      [linuxclient]]

After editing all mandatory value press ENTER and then when OK screen appear it means that file system has been exported successfully.

Once exported at Linux client machine execute following command to mount

# mount  aixhacmpserver:/oracle/log  /oracle/log



Issue which i faced during mount was following error:

"mount.nfs: access denied by server while mounting "

When i exported AIX FS using 1st method by editing file  /usr/es/sbin/cluster/etc/exports and activated changes by command #exportfs -a -f /usr/es/sbin/cluster/etc/exports . we encoutered with following error.

Issue which i faced during mount was following error:

"mount.nfs: access denied by server while mounting "

So when i used SMITTY nfs to export we didn't faced that error.

one difference which i observed while exporting again using SMITTY is following.

Hosts & netgroups allowed client access        [ ] //In this line we didn't find client hostname   


Hosts allowed root access                      [linuxclient]]

Thanks !!!
