HP-UX vPars and Integrity VM V6.3 Administrator Guide

NOTE: Creating the backing-store files of the guest on an NFS client system (that is, VSP), can

take significantly longer to complete than directly creating the backing-store files locally on the

NFS server. Therefore, create backing-stores files of the guest directly on the NFS server, if possible.

6.4.2.6 Mapping AVIO storage devices on HP-UX guests

This section explains how to map an AVIO storage device on a vPar or VM guest to an

hpvmstatus display on the Integrity VSP either at the EFI console or at the HP-UX operating

system.

The following example shows the output of hpvmstatus from the Integrity VSP:

# hpvmstatus -P aviotest

Guest Physical

Device Adaptor Bus Dev Ftn Tgt Lun Storage Device

======= ========== === === === === === ========= =========================

disk avio_stor 0 2 0 22 0 disk /dev/rdisk/disk7

The following statistics are displayed in this example:

• PciBus = 0

• PciDev = 2

• PciFtn = 0

• Addr (Target Id) = 22 (0x16)

• Lun = 0

NOTE: Addr (Target Id) is decimal in the hpvmstatus display, and PciFtn and LUN are always

zero (0).

The vPar or VM guest EFI device path encodes PciBus, PciDev, and Addr (Target Id) from the

hpvmstatus display:

PciDev

| PCIFtn

PciBus | | Addr(Target Id)

| | | |

V V V V

blk16 : Acpi(PNP0A03,0)/Pci(2|0)/Scsi(Pun16,Lun0)

PciFtn (PCI function) and LUN number are always zero (0). Addr (Target Id) becomes EFI Pun

number and is displayed as a hexadecimal number.

Following are the two methods for mapping an HP-UX 11i v2 VM guest hardware path or HP-UX

11i v2 Device Special File (DSF) to an Integrity VSP hpvmstatus display:

1. -e option of the ioscan utility

ioscan-fne displays the HP-UX hardware path/DSF and the EFI device path for the device.

The HP-UX hardware path encodes the following from the hpvmstatus display:

• PciBus

• PciDev

• Addr (Target Id)

Addr (Target Id) is encoded as an HP-UX target ID and an HP-UX LUN ID in the HP-UX hardware

path.

HP-UX target ID and HP-UX LUN ID are calculated from Addr (Target Id) in the hpvmstatus

display using the following equations:
