mount error 5 = Input/output error

I have been getting familar with a demo NetApp 8.2.1 ClusterMode in our lab. I was trying to do some SPEC testing over CIFS. So I recently setup CIFS on one of the SVMs. It seems similar for the most part as a CIFS server on 7-mode ONTAP. However, from my Redhat 5.8 VM, I can't seem to mount the CIFS share I created.

I get this message on the client:

the complete output:

[root@llsfs01 /]# mount.cifs //192.168.1.159/cifstest /mnt2 --verbose -ouser=spec,password=spec123

mount.cifs kernel mount options: unc=//192.168.1.159\cifstest,ip=192.168.1.159,ver=1,user=spec,pass=********
mount error 5 = Input/output error
Refer to the mount.cifs(8) manual page (e.g.man mount.cifs)

my system works fine doing a mount of a CIFS on 8.1.4P1 7-mode in the lab:

[root@llsfs01 /]# mount.cifs //llnsa03/spectest /mnt2 --verbose -ouser=spec,password=spec123

mount.cifs kernel mount options: unc=//llnsa03\spectest,ip=192.168.1.8,ver=1,user=spec,pass=********
[root@llsfs01 /]# mount

...

//llnsa03/spectest on /mnt2 type cifs (rw,mand)
[root@llsfs01 /]#

Any ideas what this error means?
