BL460c in c7000 with Flex-10 lost addapters after plug P700

[Xavier Amill]

We have a c7000 enclosure with two VC Flex-10 and two 3G SAS switches. We have defined server 4 identical server profiles ( copied ) into VC, and applied to first 4 BL on our enclosure. We installed ESX4 in our server and they boot up and works properly with all my defined network interfaces as we defined on our applied profile.
After power down two of our BL servers in order to plug a new P700 to connect to an external MSA2012saG3 through 3G SAS Switches, it seems as they lost his network adapters, although our VC profile has not been changed. We can see our network adapters in OA, with his MACs, but when the server boot up, it doesn’t see any nic.
