Hi all-
We have 4 hosts running vSphere 6.5 on Cisco UCS-C240-M4's. They have a vSAN configuration. I started to get the 'Lost connectivity to the device mpx.vmhba32:C0:T0:L0 backing the boot filesystem'
for no apparent reason. This is happening on only one host. I am not sure what logs I need to start checking or where to start. One thing I am interested in is seeing if there is a disk error (I know this looks like network issues, but I am curious). These machines are not UCS managed. And we are all working remotely so no physical access.
Where to start?
