There is a lot of information included in this command output. However there is a
Fusion-IO adapter called fioiom0 and there is a HP adapter called vmhba1. Possibly
a better way to display this information, one line at a time, is to use esxcfgscsidevs
–A. The command simply displays which device is attached to which
controller, without all of the other ancillary information shown above.
esxcfg-scsidevs –A

This displays which adapter a particular SCSI device is attached to. Remember that
the Fusion-IO adapter is called fioiom0 and that the HP adapter is vmhba1, so here
we can see the disks associated with each adapter. Either a EUI identifier, an MPX
identifier or an NAA identifier, identifies the SCSI devices. Different SCSI devices
from different vendors identify themselves in different ways, although all are
supported. The Fusion-IO is using EUI, whereas the HP devices use an NAA identifier.
