DXNAS fs_dhsm connection error

HI All,

Need some help. After installing DXNAS, I am trying to configure the DX-NAS environment. I am trying to configure the Celerra FileMover protocol. According to the documentation, I did the following:

1) Logged on to Celerra as nasadmin user
2) Ran "fs_dhsm -modify imddel -state enabled" where imddel is the filesystem on Celerra
3) Created a FileMover user with "/nas/sbin/server_user server_2 -add -md5 -passwd dhsm_user" with root access

Now I am trying to establish a connection from the Celerra FileMover to the secondary storage (which is the another filesystem on the same NAS). I am using the following command:

fs_dhsm -connection imddel -create -type nfsv3 -secondary 192.168.16.58:/cx340 -useRootCred true -proto UDP

but it fails with the error:
Error 13158252558: Attempt to create NFS v3 connection to secondary NFS server 192.168.16.58 failed. Mount operation failed with mount status: 13 and status: NoPermission. Make sure remote file system /cx340 is exported on server 192.168.16.58.

I have already done the following:
ON NAS: I have created the filesystem which needs to be exported
I have exported "/fs_CX340" filesystem from NAS on to 192.168.16.58 as /cx340
I have also exported "/imddel" filesystem from NAS on to 192.168.16.58 as /nas
nfs daemon is already started on 192.168.16.58.
i have also entered in /etc/fstab of 192.168.16.58, the entries for the CelerraSource (imddel) and CelerraTarget (cx340) as
192.168.16.10:/imddel /nas nfs rw,rsize=8192,wsize=8192,soft,incr
192.168.16.10:/fs_CX340 /cx340 nfs rw,rsize=8192,wsize=8192,soft,incr

Any other ideas?

Please help.

Thanks
Kamal
