[Users] Storage server

[Elad Ben Aharon]

Actually, the best way to do it would be to create another storage domain and migrate all the VMs's disks to it (you can do it while the VMs are running), then you won't suffer from a down time.
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.

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
