for XenServer, VMs need to be shut down or migrated away before  expanding a volume.

Subject: Expanding a volume on a SAN

Hi everyone,

I had a question posed to me today regarding how CloudStack and the underlying hypervisor
deal with an iSCSI volume that is expanded.

For example, let's say I'm using XenServer or ESX and I create a storage repository or datastore,
respectively, for each hypervisor based on an iSCSI target. I then tie this into CloudStack
as Primary Storage.

If I increase the size of the iSCSI target (the SAN volume/LUN), does this increased size
feed into the hypervisor and CloudStack?
