notice this will create a snapshot for your vms and may change them from
raw to qcow. also, this not supported for shared disks.
If you don't have the option to do so, the best way to do it
would be to shut down the VMs, put the storage domain to 'Maintenance' and then
perform the storage server network change. When the connection to the storage is fixed,
activate the domain and resume the VMs manually.
that's assuming the domain was added using dns and not ip address, and
that the dns expiration/caching on all hosts will notice the new ip address.

For the moment, nothing is going on. The change is planned on Thursday. So,
correct me if I'm wrong, you say that the fastest and easiest way is to
suspend all the machines, make the change of the storage server, rediscover
the iscsi server and then bring the vm's back up?
Kind regards,
Koen
