To enable the booting of a Server, after changing PCIe Slot Of The Boot Disk's SCSI SAS Host Bus Adapter (HBA) Card

When the niwot card slot location is changed, the controller definition of original HW raid volumes changes at the Open Boot Prom (OBP) 

The System can no longer boot up successfully, as OBP no longer points to a valid device definition.

Even correcting the OBP device path may not ensure a successful boot, if the Operating system device tree has not been updated as well.

This document attempts to give a high level overview of the process, considerations required and show in some detail the reconfiguration at the Server Open Boot Prom (OBP) using a simple example of a HW Raid Volume, with no logical volume manager being used, for example Solaris Volume Manager (SVM) or Veritas Volume Manager or Oracle's ZFS
