HP Integrity Virtual Machines Release Notes Version A.03.50

This delay is caused by the retry of failed commands from the nonresponding backing store.
There is currently no workaround.
8.4.5 I/O Resource Delete Using hpvmmodify Fails When Guest is at EFI
Devices configured under AVIO Stor HBA for a guest cannot be deleted (using the hpvmmodify
command) if the guest is at EFI.
Workaround: Stop the guest using the hpvmstop command and retry the command.
8.4.6 Mapping AVIO Storage Devices
This section explains how to map an AVIO storage device on an HP-UX guest to an hpvmstatus
display on the Integrity VM Host either at the EFI console or at the HP-UX operating system.
The following example shows the output of hpvmstatus from the Integrity VM Host:
# hpvmstatus -P aviotest
[Storage Interface Details]
Guest Physical
Device Adaptor Bus Dev Ftn Tgt Lun Storage Device
======= ========== === === === === === ========= =========================
disk avio_stor 0 2 0 22 0 disk /dev/rdsk/c82t15d3
The following statistics are displayed in this example:
• PciBus = 0
• PciDev = 2
• PciFtn = 0
• Addr (Target Id) = 22 (0x16)
• Lun = 0
Note that Addr (Target Id) is decimal in the hpvmstatus display, and PciFtn and Lun are always
zero (0).
The Integrity 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# are always zero (0). Addr (Target Id) becomes EFI Pun# and is
displayed as a hexidecimal number.
The two methods for mapping an Integrity VM HP-UX guest hardware path or HP-UX Device
Specific File (DSF) to an Integrity VM Host 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 tgt ID and an HP-UX lun ID in the HP-UX hardware
path.
HP-UX tgt ID and HP-UX lun ID are calculated from Addr (Target Id) in the hpvmstatus
display using the following equations:
HP-UX tgt ID = Addr(Target Id) % 16
HP-UX lun ID = Addr(Target Id) / 16
