I opened a ticket with Dell support.  They sent me a procedure to clear logs and reset using ssh(putty).  After that I was able to log in and update as needed.  
Solved: VRTX CMC update - Dell Community   See previous thread.  As instructed, I attempted to update the standby cmc first.   According to the update page, it never updated.  But now I'm getting email after email from the CMC with warnings.  Clusters 2 and 3 keep dropping out - just says slot01 and slot 02 but will come back.   Both CMC's are showing the same, older firmware 2.20.  I downloaded the latest per Dell website.   Some of the warnings: Detailed Description: CMC is unable to obtain the CPU information from the server specified in the message. This occurs if there is no communication between CMC and iDRAC.Recommended Action: Do the following: 1) Reset iDRAC. 2) Reset CMC. If the issue persists, contact your service provider.Message ID: CMC8526 Detailed Description: CMC is unable to obtain the memory information from the server specified in the message.

Will resetting either shut down my server?
