A Sun Microsystems platform, with a fiber disk as the boot disk, is dependent on the disk's World Wide Number (WWN) being included in its physical device path, in order for the system to boot properly. Below is a detail from a Sun Fire 280R system:
/pci@8,600000/SUNW,qlc@4/fp@0,0/disk@w210000203746f423,0:a Physical Device Path /pci@8,600000/SUNW,qlc@4/fp@0,0/disk@w210000203746f423,0:a WWN
If the primary boot device is replaced by a disk which has been ufsrestore'd (from a backup via ufsdump), then the WWN of this disk must be implemented into the Solaris Operating System device path, and must be associated with the correct Solaris OS logical device.
