How can verify the boot-device information in LDOM(guest)

Guest domain is configured VHBA and SAN boot configured. Here I want to know, how below virtual addresses are obtained especially "disk@w50000975a81b0005,4:a"

"

# eeprom |grep boot-device
boot-device=/virtual-devices@100/channel-devices@200/scsi@0/disk@w50000975a81b0005,4:a /virtual-devices@100/channel-devices@200/scsi@1/disk@w50000975a81b0009,4:a
boot-device-index=0
boot-device-timeout=0
