A while ago I got the error "Lost connectivity to the device mpx.vmhba32:C0:T0:L0" on a Cisco c240 M4 server. ESXi is installed on an SD card (I believe it is anyway) . We are running ESXi 6.5 with vSAN. I remember a while ago I typed in some commands and saw the SD card sgowed up red and had "0" space on it. I just can't remember what I typed in. Anyway, today I was trying various commands:
df ---> cannot open volume
esxcli storage filesystem list ---> cannot open volume
1st- how do I nail down it's the SD card?
2nd- If I were to power off this server I would lose ESXi I gather, so I would need to most likely back up the esxi config and the VDS config? What about vSAN?
Been going in circles today.
