I don't know what "scan disks", does, but it is not required.

When you open the "new/manage domain" dialog we fetch the device
list from vdsm (getDeviceList) and this perform all the steps needed to
detect resized devices.

Perhaps he can select the storage domain in storage tab and "Scan Disks" to
induce an iscsi rescan on hosts and then in manage domain see this
additional column?
Just a guess...

Hi Arman,

You don't need to remove storage from ovirt to resize a LUN, and you don't
need
to resize the pv, we can do this for you.

To resize a LUN:

1. Resize the LUN on the storage server
2. Open the "manage domain", dialog
3. Select the LUN and click the "resize" button in the table
(we should detect the new size and display button suggesting to add 11T)
4. Click "OK"

The system will make sure all hosts see the new size of the LUN, and then
it will resize the PV for you, and update engine database with the new LUN
size.

Now, in your case, we don't have any information about the issue, but if
you restart vdsm on the SPM host your issue may be resolved.

If not, please attach engine and vdsm logs.
