Feature:
Discover and login to ipv6 addresses while creating a new iSCSI storage domain.
Reason:
In case of trying to discover an ipv6 address, there's an error message. Therefore only discovery for ipv4 is being supported today.
Result:
The user can successfully discover ipv6 addresses.
This is enabled by default on clusterLevel >=4.3, but may be enabled manually on clusterLevel=4.2 if all of your hosts are >= 4.2.6 with
engine-config -s ipv6IscsiSupported=true --cver=4.2

Description

All gerrit links above are merged. What else is needed here? All the patches here are vdsm's, and they are here only because it is a clone of the vdsm bug. Engine work has not started. Would you agree to look at this sooner than later? This request has been proposed for two releases. This is invalid flag usage. The ovirt-future release flag has been cleared. If you wish to change the release flag, you must clear one release flag and then set the other release flag to ?. (In reply to Dan Kenigsberg from comment #5) > Would you agree to look at this sooner than later? You didn't leave me much choice, you already targeted it on my behalf :) (In reply to Dan Kenigsberg from comment #0) > Now that Vdsm accepts ipv6_enabled in ISCSIConnection.discoverSendTargets, Dan, has this flag, but it seems that the author adding this flag never tested it, see bug 1612958 :-) Moved to 4.2.7 not being marked as blocker for 4.2.6. ipv6IscsiSupported is true for 4.2 and still, discovery with ipv6 doesn't expose targets.
The message that appears :
"No new devices were found. This may be due to either: incorrect multipath configuration on the Host or wrong address of the iscsi target or a failure to authenticate on the target device. Please consult your Storage Administrator"
I changed the value in vdc_options and restart ovirt-engine service.
engine=# select * from vdc_options where option_name = 'ipv6IscsiSupported';
option_id | option_name | option_value | version
-----------+--------------------+--------------+---------
658 | ipv6IscsiSupported | false | 3.6
659 | ipv6IscsiSupported | false | 4.0
660 | ipv6IscsiSupported | false | 4.1
661 | ipv6IscsiSupported | true | 4.2

Hi, From a brief view on your engine log, it seems that you have a connection problem while trying to access the ipv6 address: [root@storage-ge16-vdsm2 ~]# ping6 2620:52:0:2300:868f:69ff:fef9:6760 connect: Network is unreachable Therefore, the discovery won't work unless the connection will be set up correctly. Discovery with ipv6 expose targets
