Description (partial)

UCSM GUI shows Operation patrol read failed for blades running SSD's
Patrol read process should not start when there are only SSD in the system

In my case we were seeing this issue on B200 - M4 systems with SSD drives. 

We also were seeing Thermal Issues being reported on all B200 - M4 systems SSD drives, from VMWare. 

We got these logs from syslog server:

Server 1/4:
