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

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.

Hi,
I suppose that those VMs are now in 'Paused' state, correct me if I'm wrong. After connectivity with storage comes back, all VMs which couldn't detect their disks should be resumed from 'Paused' to 'Up' state automatically. It shouldn't take them a long time to change their state (a few minutes).

Dear All,
At work, the network guys have come to a discovery that they have made a mistake in their network configuration... 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...? We are using oVirt Engine Version: 3.3.1-2.el6

In order to change the IP of the ISCSI server you need first to shutdown all the VMs. Then you need to deactivate the storage domain, and finally you can change the IP. For example, if you want to change it from 192.168.122.1 to 192.168.122.2 you can do the following: [oVirt shell (connected)]# list storageconnections --show-all id : b09b8de6-802e-4016-9c75-45e8e771ac56 address: 192.168.122.1 port : 3260 target : iqn.2014-01.com.example:example type : iscsi [oVirt shell (connected)]# update storageconnection b09b8de6-802e-4016-9c75-45e8e771ac56 --address 192.168.122.1 id : b09b8de6-802e-4016-9c75-45e8e771ac56 address: 192.168.122.1 port : 3260 target : iqn.2014-01.com.example:example type : iscsi Then you can activate the storage domain again, and start the VMs.

removing a domain *deletes* all disks/vms, other than that... (we are working on ability to detach/attach domains post 3.4)

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?

Hi,
I suppose that those VMs are now in 'Paused' state, correct me if I'm wrong. After connectivity with storage comes back, all VMs which couldn't detect their disks should be resumed from 'Paused' to 'Up' state automatically. It shouldn't take them a long time to change their state (a few minutes).

Dear All,
At work, the network guys have come to a discovery that they have made a mistake in their network configuration... 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...? We are using oVirt Engine Version: 3.3.1-2.el6
Kind Regards,
Koen

I would like to keep the vms... I know that there is a command in the CLI "update storageconnection", but how do I use this to change only the IP of the storage connection? Kind regards, Koen On Feb 6, 2014 12:55 PM, "Itamar Heim" <iheim@redhat.com> wrote:

What if I remove the "old ip" storage domains and import the same iscsi luns with the new IP, would that work?
removing a domain *deletes* all disks/vms, other than that...
(we are working on ability to detach/attach domains post 3.4)

It's not on DNS... The storage server in ovirt is on IP... So... 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>
