Mounting over NFS to Linux machine, not VM

I'm trying mount an NFS share from my Celerra on a Linux machine, but I'm concerned that in my trying to get it up and running I've either turned the nfs service off or it was never running to begin with. Let me dump some data first:

1. My Celerra control node is 192.168.25.11 and I'm trying to mount from 192.168.27.248.

2. From 192.168.27.248 I can ping across the subnet without problem. From there I can also use "rpcinfo -p 192.168.25.11" and it dumps out the following:

   program vers proto   port

    100000    2   tcp    111  portmapper

    100000    2   udp    111  portmapper

    100024    1   udp  49741  status

    100024    1   tcp  32768  status

    706000    1   udp    644

    707000    1   udp  57525

3. I notice that nfs isn't running, and when I try "showmount -e 192.168.25.11" it says, "mount clntudp_create: RPC: Program not registered," which I take means that nfs isn't running.

4. When I go to 192.168.25.11 as nasadmin and start the service via "server_nfs server_2 -secnfs -service -start" I get the same message.

5. When I start nsf as root via "/etc/init.d/nfs start" then go back 192.168.27.248 and run "showmount -e 192.168.25.11" it says:

Export list for 192.168.25.11:

/ORAPROD-NFS (everyone)

6. This is basically as it should be, but when I type "mount -t nfs 192.168.25.11:/ORAPROD-NFS /mnt/san" the follow error comes back, "mount: 192.168.25.11:/ORAPROD-NFS failed, reason given by server: Permission denied"

7. I've checked my EMC Celerra Manager and "server_export server_2 -list" and both root and access grant permissions to 192.168.27.248/255.255.255.0 yet I cannot connect.

8. Also, just to provide all info, "server_mount server_2" shows the following settings: "ORAPROD-NFS on /ORAPROD-NFS uxfs,perm,rw,uncached,sync,no_root_squash"

I've tried everything short of calling the installer. Does anyone have any ideas? Any help would be appreciated. Thanks!
