Re: kapil.chitkara@gmail.com

Hi Kapilchi, in order to create a new nas_pool, you need to use the "Provision Storage For File" wizard.

Go to the File Dashboard:

8.4 - System - Sytstem Dashboard - File Dashboard

9.0 - System - File

Once you click on "Provision Storage for File" you will be brought through a wizard, which basically creates a masking view, but defaults to the eNAS IG & PG.

Once this is complete, launch UniSphere for VNX (available from the same file dashboard) and when you get logged in, run "Rescan Storage System" from the Storage tab. You will then see a new nas_pool, with the same name as the one you gave to the SG you created during the "Provision Storage for File" wizard.

You will also find a lot more info in this doc, I hope you find it useful. I put it together, so if you are stuck for anything, just ping me and we can figure out how to help you.

Re: kapil.chitkara@gmail.com

Hi Kapil,


Control Station failover will not initiate any vdm failover, nor will a local DM failover for that matter.


If you want to initiate a vdm failover, you could bring down the interface of the vdm on the primary site


     server_ifconfig <server_x> <interface name> down


This will bring down the interface on the source side, and eNAS will wait, I think it is 2 minutes to see if there is a local failover initiated, (there wont be) and then FAR will start a failover to the remote side.


Obviously do not run these tests in a production environment.


FOR cifs CA, you need to set params at BOTH mount & export


server_mount <vdm> -o smbca <fs> <mnt pt>

server_export vdm_xx -P cifs -name xx -option type=Global:CA <mt pt>

Re: kapil.chitkara@gmail.com

Guys, i am stuck with replication..When i am trying to ping source control station ip from source data mover it is not working and validation between source dm to destination dm is also failing...As per network and firewall team everything seems to be ok...Not sure if this require static route or something...

Note: In this case i am using nas_replicate feature not FAR as we don't have SRDF license

Re: kapil.chitkara@gmail.com

Hi, have you created an interface on the DM, on the same subnet, that your control station ip is on?

Similarly, have you got an interface from the same subnet on both DM's?

Can you share the output of the below command from both sides please:

server_ifconfig server_x -all

(obviously replace the x in server_x, with the data mover you are working on, ie server_2)

Re: kapil.chitkara@gmail.com

My control station and datamover are part of different subnet but as per network team all vlan have trust so they should communicate to each other.

Not sure if I have to make changes on Cisco nexus which is part of this converged vblock
