I have two R710's, both with the internal SD modules that ESXi is booting off. Recently, I have started getting 'Lost connectivity to the device mpx.vmhba36:C0:T0:L0 backing the boot filesystem /vmfs/devices/disks/mpx.vmhba36:C0:T0:L0. As a result, host configuration changes will not be saved to persistent storage." on one of the hosts. Before I go 'randomly' changing parts, does anyone have any suggestions on how I might isolate what exactly is causing the issue? The SD module, the SD Card, the front panel board that the module is connected to, etc?
