Issue



During the NFS mount to index a Replication Director snapshot on a NetApp Volume, the NFS mount command will fail with Permission Denied.


Error



Status 43 - unexpected message received


Environment



RedHat Enterprise Linux 6.1
NetBackup 7.5.0.4
NetApp Plug-In 1.0 for NetBackup
NetApp Ontap 7.3.6 or newer
 


Cause



If the NetApp volume options for convert_ucode and create_ucode are not enabled (off by default) on the volume where Replication Director creates snapshots, the Indexing operation will fail with a 'permission denied' error. The error occurs when bpfis calls the mount command to NFS mount the export on the Filer for the client data. The log extract below shows an example of the error.

Solution



A NetApp Volume that will host Replication Director managed snapshots must be created with the convert_ucode and create_ucode options enabled.

Usage Details:

convert_ucode on | off

Setting this option to on forces conversion of all directories to UNICODE format when accessed from both NFS and CIFS. By default, it is set to off, in which case access from CIFS causes conversion of pre-4.0 and 4.0 format directories. Access from NFS causes conversion of 4.0 format directories. The default setting is off.


create_ucode on | off

Setting this option to on forces UNICODE format directories to be created by default, both from NFS and CIFS.By default, it is set to off, in which case all directo-ries are created in pre-4.0 format, and the first CIFS access will convert it to UNICODE format. The default setting is off.

To enable the convert_ucode and create_ucode options, enter the following commands at the Filer Command prompt:

vol options volname convert_ucode on
vol options volname create_ucode on

Verify volume settings by running the following command at the NetApp Filer Command prompt:

vol options volname
