Ok great, I can see the different storage that I want to import, but I can't see the VMs on the un-connected pool. So anyway I have to go further and import the storage domain passing the alert message. Am I right ? No other way to see the VMs in SD : [root@unc-srv-hyp1 ~]$ vdsClient -s 0 getStorageDomainsList 7e40772a-fe94-4fb2-94c4-6198bed04a6a 0fec0486-7863-49bc-a4ab-d2c7ac48258a d7b9d7cc-f7d6-43c7-ae13-e720951657c9 1f6dec51-12a6-41ed-9d14-8f0ad4e062d2 f9a0076d-e041-4d8f-a627-223562b84b90 04d87d6c-092a-4568-bdca-1d6e8f231912 [root@unc-srv-hyp1 ~]$ vdsClient -s 0 getStorageDomainInfo 7e40772a-fe94-4fb2-94c4-6198bed04a6a uuid = 7e40772a-fe94-4fb2-94c4-6198bed04a6a vguuid = zwpINw-zgIR-oOjP-6voS-iA2n-zFRB-G76sSQ state = OK version = 3 role = Regular type = ISCSI class = Data pool = ['f422de63-8869-41ef-a782-8b0c9ee03c41'] name = VOL-UNC-PROD-01 [root@unc-srv-hyp1 ~]$ vdsClient -s 0 getStorageDomainInfo 0fec0486-7863-49bc-a4ab-d2c7ac48258a uuid = 0fec0486-7863-49bc-a4ab-d2c7ac48258a vguuid = ta2ZFC-UwtO-xANp-ZK19-rWVo-1kBJ-ZrsQrN state = OK version = 3 role = Regular type = ISCSI class = Data pool = ['c58a44b1-1c98-450e-97e1-3347eeb28f86'] name = VOL-UNC-TEST [root@unc-srv-hyp1 ~]$ vdsClient -s 0 getStorageDomainInfo d7b9d7cc-f7d6-43c7-ae13-e720951657c9 uuid = d7b9d7cc-f7d6-43c7-ae13-e720951657c9 vguuid = zyiwLa-STgp-v3r8-KJqj-1AIP-rC2k-4NuXqf state = OK version = 3 role = Regular type = ISCSI class = Data pool = ['f422de63-8869-41ef-a782-8b0c9ee03c41'] name = VOL-UNC-PROD-02 [root@unc-srv-hyp1 ~]$ vdsClient -s 0 getStorageDomainInfo 1f6dec51-12a6-41ed-9d14-8f0ad4e062d2 uuid = 1f6dec51-12a6-41ed-9d14-8f0ad4e062d2 vguuid = 6itdyW-WLid-fTu6-HAJd-dpSj-HpbH-T4ZSVA state = OK version = 3 role = Regular type = ISCSI class = Data pool = ['c58a44b1-1c98-450e-97e1-3347eeb28f86'] name = VOL-UNC-NAS-01 [root@unc-srv-hyp1 ~]$ vdsClient -s 0 getStorageDomainInfo f9a0076d-e041-4d8f-a627-223562b84b90 uuid = f9a0076d-e041-4d8f-a627-223562b84b90 version = 0 role = Regular remotePath = unc-srv-kman:/var/lib/exports/iso type = NFS class = Iso pool = ['c58a44b1-1c98-450e-97e1-3347eeb28f86'] name = ISO_DOMAIN [root@unc-srv-hyp1 ~]$ vdsClient -s 0 getStorageDomainInfo 04d87d6c-092a-4568-bdca-1d6e8f231912 uuid = 04d87d6c-092a-4568-bdca-1d6e8f231912 version = 3 role = Master remotePath = unc-srv-hyp1.cfu.local:/exports/import_domain type = NFS class = Data pool = ['c58a44b1-1c98-450e-97e1-3347eeb28f86'] name = VOL-NFS [root@unc-srv-hyp1 ~]$ vdsClient -s 0 getVmsList c58a44b1-1c98-450e-97e1-3347eeb28f86 1f6dec51-12a6-41ed-9d14-8f0ad4e062d2 No VMs found.

Is there any command to verify if the storage domain contains VMs or not ?
You can execute this on one of your hosts. # vdsClient -s 0 getStorageDomainsList to get storage domain list, than # vdsClient -s 0 getStorageDomainInfo <domain UUID> for each of them till you identify the domain you are looking for. You can also find there the pool UUID. Than # vdsClient -s 0 getVmsList <pool UUID> <domain UUID> To get the list of VMs on that storage.

To complete my previous post, if this storage domain doesn't contain VM, but just Disks attached to other VMs from other Storage Domain. How can I check it before breaking the rest of my data importing other SD ??? Thanks
No I don't see any VM images, that the big problem...
Ok, I've done that action, but after I don't any "Import VMs" and "Import Templates" tabs.... What's happening ???? Alain
You don't have to explicitly re-import each VM. You should find your storage domain with all the preexisting VM images.

Hi, The plan using import Domain seems to be OK, but when I finalize the importation of a Data/iScsi I have this alert :
Storage Domain(s) are already attached to a Data Center. Approving this operation might cause data corruption if both Data Centers are active.
How can I detach this domain to a non visible old Data Center ?? Can I pass this alert without data lost ?
If the old engine is no more active and the new one is using a new database and not an imported one you are safe to proceed.
Thanks Alain

I plan to reinstall on a cloned VM from the original one, I have cleaned the previous version, and made an engine-setup. So I have backups from the previous Manager, I can backup to the new one. But, reading the overt-engine-backup, it seems to be possible only before doing engine-setup. Is that right or may I launch a backup after an engine-setup ? An engine-clean is enough to use engine-backup ?
Thanks

Hi I want to reinstall a new clean oVirt Manager, and I have a question : If I install a new manager, do I recover the datacenter and all the Vms installed in it without any lost of data ? What is the best practice to do this safely ? Thank you for your help Alain
Are you planning to install on a new host/VM?
You have basically two alternatives: A. backup the DB and restore it on the new engine as described here: http://www.ovirt.org/Ovirt-engine-backup
B. Start from scratch with a new engine on a new DB and re-import existing storage domains: http://www.ovirt.org/Features/ImportStorageDomain
Option B involves a lot of manual steps but it could be also used as a disaster recovery flow when the DB is for any reasons lost or corrupted.
