1.You can reseat the IOMs you will need to reseat one IOM at a time starting with the IOM connected to the subordinated fabric, This should not cause a complete outage. However, you should perform this during a maintenance window. Please note, this method does not always clear the i2c bus 100% of the time. You may have to use option 2 if this is the case.
