Need to back up sd card, which is disk mpx.vmhba32:C0:T0:L0
cd into a datastore and run this command:
[root@localhost:/vmfs/volumes/556c6cc9-7b6835f6-d569-ac162da1c290] dd if=/dev/disks/mpx.vmhba32:C0:T0:L0 of=./sdBackup.img conv=notrunc
dd: /dev/disks/mpx.vmhba32:C0:T0:L0: Function not implemented
Looking for some ideas.
