What are my options in this case? you would need to 'edit the connection'. since 3.3.1 this is possible via the rest api without hacking the db: http://www.ovirt.org/Features/____Manage_Storage_Connections <http://www.ovirt.org/Features/__Manage_Storage_Connections> <http://www.ovirt.org/__Features/Manage_Storage___Connections <http://www.ovirt.org/Features/Manage_Storage_Connections>> Thanx!

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. ----- Original Message ----- From: "Koen Vanoppen" <vanoppen.koen(a)gmail.com <mailto:vanoppen.koen@gmail.com> <mailto:vanoppen.koen@gmail.__com <mailto:vanoppen.koen@gmail.com>> <mailto:vanoppen.koen@gmail. <mailto:vanoppen.koen@gmail.>____com <mailto:vanoppen.koen@gmail.__com <mailto:vanoppen.koen@gmail.com>>>> To: "Elad Ben Aharon" <ebenahar(a)redhat.com <mailto:ebenahar@redhat.com> <mailto:ebenahar@redhat.com <mailto:ebenahar@redhat.com>> <mailto:ebenahar@redhat.com <mailto:ebenahar@redhat.com> <mailto:ebenahar@redhat.com <mailto:ebenahar@redhat.com>>>>__, users(a)ovirt.org <mailto:users@ovirt.org> <mailto:users@ovirt.org <mailto:users@ovirt.org>> <mailto:users@ovirt.org <mailto:users@ovirt.org> <mailto:users@ovirt.org <mailto:users@ovirt.org>>> Sent: Tuesday, February 4, 2014 2:57:57 PM Subject: Re: [Users] Storage server 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?

After connectivity with storage comes back, all VMs which couldn't detect their disks should be resumed from 'Paused' to 'Up' state automatically.

The Storage server that we use as ISCSI target in oVirt, is in the wrong VLAN, so the wrong IP address... What is the best way to make sure that all of our vms (40) that are using this scsi storage will come up again after the storage server has changed his ip? What are the best steps to be taken...?
