Hi, Turned out that there was no problem updating the existing CMC, but the one that went off the air had to be replaced and then all was OK. thx JB
Hi, I can only see 1 CMC after a firmware update of an M1000e chassis. Before the update, the CMC's were fully redundant and had been for months. When the Update Tab is selected, only one CMC is visible.  Should I proceed with applying the 3.21 CMC Update to the active CMC?   And: 1. Will it cause all blades in the chassis to lose connectivity? 2. Will it fix the redundancy problem? Thx, John Bradshaw
eek...Help - CMC redundancy lost during update to 3.21 from 3.20 M1000e Chassis
