HP EVA 8100 DR failover error

[Erion]

We use two HP EVA 8100 with CA synchronous replication. we are trying to fail over a DR group, but without success. the error message is No Lock. both disks are not presented to any server.

There is no attachment.

I don't know if the following is the reason, but in the early days I had to present a virtual disk before I could do certain CA tasks. For that I used a dummy Host entry with a non-existing WWN.
