Hi, I performed the upgrade from UCS 1.4 to UCS 2.0 successfully. Then I tried to upgrade all blade servers from ESX4i to ESX5i. Here is the list of results.
1. B200 M2 with M71KR-E -> success.
2. B200 M2 with M81KR -> success.
3. B200 M2 with M72KR-Q - failed
Note: All firmware and bios were activated to 2.0 level.
The B200 M2 wth M72KR-Q was running ESXi4 in UCS2.0 fine before upgrade.
My first attempt was to upgrade from ESXi4 to ESXi5. The error message shown that ESXi5 detect no NICs. The blade server automatically reboot and reverted back to ESXi4.
The second attempt was to directly install ESXi5. The same error message and the system was limited to the only choice of cancel the installation and reboot.
The third attempt was to use vCenter 5.0 VUM to remotely upgrade the server from ESXi4 to ESXi5. Same error message and the system was rendered to rebooting cycles.
Has any of you seen this? Thanks.
