Problem : nfs exports issue while performing Aix client restoration through nim ?
We have created machine,spot,mksysb resource. We have got following issue while assigning the mksysb and spot resources to machine.
0042-001 nim: processing error encountered on “master”:
0042-124 c_ch_nfsexp: NFS option sec=sys:krb5p:krb5i:krb5:dh is NOT supported
rc=1
0042-001 m_bos_inst: processing error encountered on “master”:
0042-175 c_ch_nfsexp: An unexpected result was returned by the
“/usr/sbin/exportfs” command:
exportfs: 1831-193 /lpar_mksysb/laq9etlit1_maksysb_09_june_2009: parent-directory (/lpar_mksysb/)
already exported
Solution: nfs exports issue while performing Aix client restoration through nim ?
1) Perform a NIM-reset of the client in question (choose ‘deallocate resources’ and ‘force’).
2) Issue ‘showmount -e’ at the NIM master. If the name of a NIM client shows up in one of the paths, NIM-reset that client, too. Use ‘deallocate resources’ and ‘force’ like above.
3) Never export NIM filesystems on your own. If you have /lpar_mksysb in your /etc/exports, remove that entry and additionally issue ‘exportfs -u /lpar_mksysb’
btw. the 0042-124 is only a warning, the important things are the 0042-175 and 1831-193
If you must export NIM directories for some reason, choose only ‘sys’ as security option, since it’s the only option supported by NIM.
