VNX-for-File NFS network interface on a VDM

You have to add interfaces to the VDM so you can mount the NFS export by

diferent Interface:

nas_server -vdm

NFS network interface on a VDM

Just to clarify, I also have several CIFS shares on the same VDM and they need to use a different network interface than the NFS one. thanks.

So I need to create the new interface first, then I can attach it to the VDM but ONLY using the CLI, correct?

Is there any way I can do it from Unisphere?

Thats correct.

With this you can see the attached intefaces protocols:

nas_server -info -vdm

Here the interface "red2" is attached to the VDM to present NFS exports.

Take in account that if you exports NFS from the VDM, it will not shown in

the GUI, you can only manage them from CLI.

If you create the NFS from the GUI it will be mounted on server_2 (Physical

DM)

You can export a VDM filesystems throught the Physical DM also, but if you

are trying to export NFS inside the VDM, the only way is throught CLI.

sorry for the re-post - reply by EMail filtered part of my reply

CIFS and NFS can use the same interface just fine

If you have a file system that is mounted on a VDM you have two choices for NFS export:

1. The old way – export the complete path incl. root_vdm from an interface belonging to the physical data mover
   you use server_export server_2 –P nfs …. /root_vdm_ /
   (you need to find out which number X is for your VDM with server_mount)
   clients can mount /root_vdm_ / from any interface on the data mover (except VDM attached ones)
   
   
2. newer VDM NFS export using the path relative to the vdm root
   attach an interface to the VDM using nas_server –vdm -attach
   then export from the VDM with server_export -P nfs /
   clients would mount / from an interface attached to that VDM

For both you need to use the CLI to create the NFS export – with 1) once its created you can see and change it in the GUI – with 2) you cannot

Both ways serve the purpose of making a fs mounted on a VDM available for NFS clients.

With the new method in 2) you get some benefits like:

• Through the attached interface *only* file systems mounted on the VDM are accessible – not others on a different VDM or physical DM (security)
• Export is stored in the VDM config – so if you replicate the VDM the export automatically gets replicated
• You could use different DNS/LDAP/NIS/… settings for each VDM

IF you need these is your choice

For CIFS alone you don’t need to attach an interface to the VDM – with CIFS you specify which interface(s) a particular CIFS server is accessible through when creating the CIFS server.

For details please look at the NFS and the VDM manuals in PDF format – available from support.emc.com

Hope that helps clarify

No problem – I just found out that replying be Email also seems to filter out some parts – like if you use brackets

Yes, the parameters of the command was putted between < > ... and was gone ... The ECN is best way to reply I think.

Thx

Yes, I will reply trough ECN to leave out the signature ... sorry.

Alvaro,

when replying by EMail could you please leave out the signature ?
