OK, great - thanks!

So, it sounds like on XenServer, you have to perform some manual activity
for it to see the new size of the iSCSI target (and there is probably a
similar requirement with ESX), but CloudStack will notice the size
difference automatically (once the storage repository or datastore has been
manually re-configured).
