Welcome to HP-UX for IA64
setting hpux path(\EFI\HPUX)...
type 'fs[x]:' where x is your bootdisk (0, 1, 2...)
type 'hpux' to start hpux bootloader
Shell>
Now we can correlate the hardware device path with the EFI device mapping, e.g.:
fs5: Acpi(HWP0002,100)/Pci(1|1)/Scsi(Pun2,Lun0)/HD(Part1,Sig9C8E9EE8-...)
Path component
meaning
Acpi(HWP0002,X)
Relevant device is installed to Pci.host bus
(X = PCI host bus number)
Pci(D|F)
PCI installation info.
D = PCI device/slot number. F = PCI function number
Scsi(PunX,LunY)
Physical location of device connected to card. In this case SCSI
disk. X = SCSI ID, Y = LUN ID (c#tXdY in device file)
HD(Part1,Sigxxxxxxxx)
SCSI disk drive information.
Partition and signature
In this case it is the disk at HW path 0/1 /1/ 1. 2.0 with device file c3t2d0
• ACPI(HWP0002,100) correlates with 0/1
• PCI(D, -) correlates with /1/, which is the PCI device or slot number.
• PCI(-, F) correlates with 1., which is the PCI function number.
• SCSI(Pun, Lun) correlates with the final 2.0 which specifies the physical location of the SCSI
device connected to the card.
As of UX 11.23 there is a new –e option for ioscan(1M) that displays EFI partitions:
# ioscan -e -fnkCdisk
