How to change NFS datastore subnet

[valicon]

I created a NFS datastore on a NetApp at 192.168.5.x and only used the default vswitch which had the VM group and management group on it. I have now created a seperate vswitch for the NFS traffic, created vifs on the NetApp and setup that subnet on a 172.16.10.x subnet. I tried adding the same datastore with the new subnet and same volume through the Add Storage link in the vSphere client but it gave an error. How can I do this? Do I need to re-export the NFS volume?  I have a few VMs on the datastore and I dont want to lose any data. What is the best way to do this?

Thanks

Hi!

You have to unmount the datastore first.

Here's a CLI version of how to do it:

Shut down the VMs residing on the datastores (via vSphere Client)

- Enter maintenance mode:

$ vimsh -n -e /hostsvc/maintenance_mode_enter

- For each datastore, delete the old, and re-add it with new address (and exact same label):

$ esxcfg-nas -d <label>

$ esxcfg-nas -a --host <new_name> --share <remote_nfs_share_path> <label>

- Mount the datastore

$ esxcfg-nas -r

-Exit maintenance mode:

$ vimsh -n -e /hostsvc/maintenance_mode_exit

You can do it in vSphere Client aswell

If I delete the old will I lose any data?  What about the VM's that are on that datastore?

Isn't there something that I need to do on the NetApp?
