had a  controller 0 error with C2F battery issue. pulled out the SD card and replaced the controller 3 days ago, and ran some testing. new controller was on 7.1.14 and controller 1 was on 7.1.5. So i upgraded to 7.1.5. The other member of the group has both controllers still on 7.1.5.

During the move from maintenance group, back into production, there appears to have been an issue with the one, or both, controllers "not installed" and it ended up taking down all our VMs that were running at the time. After digging into this, i decided to move the member back into maintenance pool, and now I have seen the same errors from both controllers again??

Any ideas? could this be a known issue with this version of firmware when moving the member?
