Hi Ted, Can you please clarify how did you lock or what do you mean by locking “Physical node 1”. In OpenSAF, you can lock a node like sc-1, sc-2, pl-3, etc one at a time.

The “lock” operation would “terminate” all the virtual machine running on that physical node. I have expected that the “active” role would switched to another VM running on another compute node, which I have configured “1+1” protection relatiosnhip. But when surprised me is that that “controller” vm switched very quickly, but the payload vm did not switched(the “standby" vm kept in “standby” although “active” VM has been terminated). I have captured the packet on now “active” controller, and noticed that it has not received packets from(211.7 -- former “active” payload, but has been terminated" for long), but keep sending arp packet asking “who has 211.7”. Please see attached file for packet I have captured. Note: physical node 1 physical node 2 before lock: sc-1(211.2 )-active sc-2(211.3) - standby pl-3(211.7) -active pl-4 (211.7) - standby after lock sc-1 terminated sc-2(211.3) became active pl-3 termianted pl-4(211.7) kept “standby” The packets were captured on 211.3 Thanks.

Regarding the multiple fail-over, we tested the blade fail-over on which 6 VM's (1 Active controller and 5 payloads) were placed. OpenSAF works like a charm here. First controller is failed-over, then notification for other payload nodes is received by new Active controller, so multiple fail-over in a correct sequence works very well with OpenSAF. I am using opensaf 4.2.0 and TCP as a OpenSAF transport.

I haven't joined OP-NFV. If the " virtualized environment " is only requirement, then OpenSAF can run without any problems. But I guess, there may be more requirements than that. We are working on Cloud requirements for OpenSAF and there has been few tickets raised.
