Adding an additional local storage to an existing XENServer

Add the new physical device “/dev/sdb” as second local storage to an existing Citrix XENServer installation:

(Note: I use XENServer 5.6)

xe sr-create content-type="local SR" host-uuid=(uuid of your xenserver host) 
type=(ext or lvm) device-config:device=/dev/sdb shared=false 
name-label="Second local storage"

The command returns the UUID of your new storage repository (SR).

Example:

xe sr-create content-type="local SR" host-uuid=d06d7c86-08af-4f87-9188-bd287daac20b 
type=lvm device-config:device=/dev/sdb shared=false name-label="Second local storage"
6b9fe5d2-bf6c-d776-dfb0-743f5b1f397c

If you want to set the new SR to the new default SR:

xe pool-param-set default-SR=[YOUR NEW SR UUID]  uuid=(uuid of your xenserver host)

Notes: You can use “pvdisplay” to lists all physical volumes.
