LIF has no data-protocol assigned after metrocluster switchover

jenoptik

Hello 🙂

I recently configured a metrocluster. The metrocluster itself is up and running, and the "-MC" SVM is running fine. Also the LIFs assigned to that SVM are there but they don't have the iscsi data-protocol assigned.

Anyone seen this issue before?

Best regards,

Toni

I have to verify it, but maybe I got the solution!

I searched for a replication/confirguration resync option and figured out metrocluster vserver resync -cluster lsc-rzs-11 -vserver lsc-rzs-iscsi resynchronizes the vservers configuration. And now there is the data-protocol:iscsi setting as expected.

After I verfied switchover I will let you now if it's solved.

Hello,

Can you run the below command to verify lif replication was successful:

cluster::>metrocluster check lif show

Thanks

Hi and thank you for the answer. The output of metrocluster check lif is:

Hm.... Why there is no data-protocol: iSCSI? It is on the original cluster.

Can you try doing a metrocluster vserver resync

Thank you. We had the same idea.

So, the problem is solved.

Switchover works as expected.
