UCS FI upgrade issue IOM becomes inoperable probably due to wrong procedure

HI Team,

We are doing an installation of UCS Bseries servers with 5108 chassis and 6296UP Fabric Interconnects. Was trying to upgrade the firmware version of all the components to 3.1(1e) from 2.2(2C). During the upgrade of the secondary FI-B after checking the FSM progress to 100 immediately upgraded the Primary FI A and changed the cluster lead to B, however I missed an important step of checking the FSM status of the IOM modules and also did a immediate cluster failover to B with the IOM not getting upgraded. Right now I see that the IOM module shows inoperable and the IOM module continuously flaps. Would like to know how can I resolve this issue. Would like to get your help on how to get the IOM module which is connected to FI-B up
