Import FC Storage as iSCSI
Hello. I have created an FC Storage Domain and made snapshots of all LUNs on the SAN. Now I want to use those snapshots on another Data Center over iSCSI connection to test recovery. I can import the domain, but the domains Storage Type is FC and I can't attach it to host. Is it possible to change domain type to iSCSI or some other way to import storage domain. Thank you. Raul

Just select iSCSI as thetype when you import it. This is the type of the new domain. Vered

Hi. I have done this because this is the only way to access iSCSI target. But after import it shows up as FC (the original storage domain type). Where does this information come from? I have DataCenter setup from about version ovirt-engine-3.3.2. Thank you. ----- Original Message -----

Hi Raul, The storage domain type is determined from the Storage Domain meta data. If your storage domain was previously an FC Storage Domain, the import process will read this from the meta data and import it as an FC Storage Domain. This behavior should be changed so the storage type will be determined by the user instead from the meta data, I've opened a bug on this issue for 3.5, https://bugzilla.redhat.com/1157240.

I believe so, I've tried now to import an existing iSCSI Storage Domain after changing its meta data from ISCSI to FCP and it seems to work well, the Storage was imported as Fibre Channel.

Hi. Thank you for looking into this. Does this only affect the import or influences also the process of attaching storage domain to Data Center (you can't attach iSCSI Storage Domain to FC DC and vice versa?) If I understand correctly, the Data Center's storage type is set at the initialization time, when the first storage domain is attached and you can't change it afterwards. In previous versions you could clearly see the DC storage type, now it's not visible. Regards. Raul ----- Original Message -----

Hi Raul, for now, the fix should include the ability to "switch" storage types only through the import process,and not through the attach process. I think that the import process might be enough because you can always remove the Storage Domain and re-import it to the setup as another storage type.
If I understand correctly, the Data Center's storage type is set at the initialization time, when the first storage domain is attached and you can't change it afterwards. In previous versions you could clearly see the DC storage type, now it's not visible.
You are right, mixed type data center is a feature introduced in version 3.4 (see http://www.ovirt.org/Features/Mixed_Types_Data_Center), There should be only two type of Data Center local and shared. The import Storage Domain feature is supported only from version 3.5 so it can only be supported in mixed type Data Centers.

When I try to import existing FC storage domain, which consists of two NetAPP LUN-s cloned from NetAPP snapshots, I get: Error while executing action Attach Storage Domain: The Domain is already used by another Data Center. In order to use it, detach it from the Data Center it is currently attached to. Does this mean, that to import existing storage domain, it must be first (cleanly) detached?

Which Data Center version are you using to attach the Storage Domain to? If the storage domain meta data indicates that it is already attached to another Data Center (after DR for example). then you the attach of it will only be supported for Data Center 3.5.

When I try to import existing FC storage domain, which consists of two NetAPP LUN-s cloned from NetAPP snapshots, I get:
Error while executing action Attach Storage Domain: The Domain is already used by another Data Center. In order to use it, detach it from the Data Center it is currently attached to.
Does this mean, that to import existing storage domain, it must be first (cleanly) detached?
Regards.

Hi.
Thank you for looking into this. Does this only affect the import or influences also the process of attaching storage domain to Data Center (you can't attach iSCSI Storage Domain to FC DC and vice versa?)
Hi Raul,
for now, the fix should include the ability to "switch" storage types only through the import process,and not through the attach process. I think that the import process might be enough because you can always remove the Storage Domain and re-import it to the setup as another storage type.
If I understand correctly, the Data Center's storage type is set at the initialization time, when the first storage domain is attached and you can't change it afterwards. In previous versions you could clearly see the DC storage type, now it's not visible.
You are right, mixed type data center is a feature introduced in version 3.4 (see http://www.ovirt.org/Features/Mixed_Types_Data_Center), There should be only two type of Data Center local and shared. The import Storage Domain feature is supported only from version 3.5 so it can only be supported in mixed type Data Centers.
Regards. Raul

Hi Raul,
The storage domain type is determined from the Storage Domain meta data. If your storage domain was previously an FC Storage Domain, the import process will read this from the meta data and import it as an FC Storage Domain.
This behavior should be changed so the storage type will be determined by the user instead from the meta data, I've opened a bug on this issue for 3.5, https://bugzilla.redhat.com/1157240.
so i guess for now the metadata can be changed as a workaround?
I believe so, I've tried now to import an existing iSCSI Storage Domain after changing its meta data from ISCSI to FCP and it seems to work well, the Storage was imported as Fibre Channel.

Maor, does this ring in bells wrt importing a storage domain?
