Configuring the NFSv4 client on AIX

Edit online

This topic describes how to configure the NFSv4 client on AIX.

Prerequisites: For AIX 6.1 an operating system level of 6100-05-01-1016 or higher.

  1. Configure the domain name:
    1. Configure the domain name to the same name as defined in z/OS® UNIX /etc/resolv.conf or as defined with z/OS NFS Server attribute NFSV4DOMAIN.
    2. Execute smitty chnfsdom.
    3. Change NFS Local Domain to <domain name from z/OS UNIX resolv.conf>.
    4. Verify the domain name setting.
    5. Execute chnfsdom.
  2. Configure the automounter service:

    Modify auto_master and create an auto.ha2.sapmnt to allow the automounter to mount the SAP file systems on demand with NFSv4 protocol.

    The mount statements must include vers=4 and mount options mvsmnt and rdrverf.

    Note: The /etc/auto_master file is only read when the automount command is initially executed. Changes to it do not take effect until the automount command is run again.
  3. Configure NFS client service
    1. Start the NFS services that are required for NFSv4.
    2. Execute startsrc -s nfsrgyd
    3. Verify the NFS services.
    4. Execute lssrc -g nfs
    The services nfsrgyd and nfsd show active in the Status column.
