To add storage to ESX servers
Right-click on a datacenter, cluster, folder, or an ESX server in the vSphere Client window. Choose Add storage from clustername, where clustername is the FileStore cluster that has been registered with this vCenter Server, and from which you want to add storage.
In the ESX Servers table, check the ESX server(s) to which you want to add storage.
The ESX servers that are displayed under the ESX Host Name column depend on what entity you selected in step 1. If the entity selected is a datacenter, all the ESX servers in the datacenter are displayed. If the entity selected is a folder, all the ESX servers in the folder are displayed. If the entity selected is a cluster, then all the ESX servers in that cluster are displayed.
Basically, a datacenter, a cluster, or a folder are containers of ESX servers.
Virtual IP Address
In the NFS Storage Properties table, in the drop-down menu, select a virtual IP address.
In the NFS Storage Properties table, in the drop-down menu, select the directory path of the NFS share.
Mount NFS Read Only
In the NFS Storage Properties table, check if you want the mounted NFS share to be read-only.
A datastore name is automatically generated based on the virtual IP address and the NFS share that you selected.
You can change the datastore name to whatever you choose.
The datastore name must be unique. If the datastore name is not unique, you receive an error message after clicking Submit.
