Symptoms

When issuing 'probe-all' instead of a "probe-scsi-all" command in OBP of M3000/M4000/M5000, the subsequent boot causes a "Last Trap: Data Access Error"
This also Degrades the MBU on an M3000 or an IOU on the M4000/M5000 with ereport.chassis.SPARC-Enterprise.asic.pci_sw.fe
The customer or field may interpret this as a HW error and would replace MBU_A or IOU

The M8000 and M9000 does not have this issue

Changes
