Preamble
For performance reason doing Integrity VM o HPUX 11.23 mist be avoided, because in this OS release the disks that are allocated to the host must be put in a LVM Volume Group (VG) and the Logical Volume (LVOL) that will be created in the VG host will be seen as disk in the VG guest. This is extremely inefficient because doing LVM over LVM. HPUX 11.31 is avoiding this stupid configuration…
You may also seen in the HPUX official configuration that doing Integrity VM for high I/O demanding applications such as databases should be avoided…

Powerpath is now replaced by the new HPUX 11i v3 I/O stack. Your new favorite tool for configuration will be scsimgr.
From The Next Generation Mass Storage Stack HP-UX 11i v3:
PowerPath does not manage multi-pathing on HP-UX 11i v3. Native multi-pathing is used for EMC devices. For information on migrating from PowerPath to native multi-pathing, see the HP-UX 11i v2 to 11i v3 Mass Storage Stack Update Guide in For More Information.
From HP Integrity Virtual Machines Version 4. 1 Installation, Configuration, and Administration:
The Integrity VM upgrade tool is focused on the devices that are used to back guest virtual devices. Each guest configuration is queried for its virtual backing storage. The guests device list is then compared to knownmultipath solutions,AutoPath, Secure Path, PowerPath PVLinks, or Veritas DMP devices to detect any dependencies.
Because the 11i v3 storage stack supports native multipath access to devices through the agile device names, the common solution for old 11i v2 multipath solutions is to remove them and change the applications to reference the new agile devices.
From HP Integrity Virtual Machines Version 4. 1 Release Notes:
EMC PowerPath could be used with legacy DSFs (whole disk or LUN) or with legacy whole disk DSF in a Volume Group (LVM Logical Volumes).
From HP-UX 11i v3 Native Multi-Pathing for Mass Storage:
Pre-HP-UX 11i v3 multi-pathing add-on products are no longer required.

"round_robin" is the default, "least-command-load" policy using rule "a path with the least number of outstanding I/O requests is selected", could be interesting to measure its benefit.
A VM Host administrator specifies this SCSI MPT adapter using the following:
device:scsi:pcibus,pcislot,scsitgt
where:
- device is one of the following: disk, dvd, tape, changer, or burner.
- pcibus is an integer from 0-6. The virtual AVIO and MPT adapters are supported only on PCI buses 0-7.
- pcislot is an integer from 0-7. A PCI function number is not specified. It is implicitly zero because the virtualMPT storage adapter supports only a single channel.
- scsitgt is an integer from0-14 for virtual SCSI (15 is reserved for the virtual SCSI adapter) and 0–127 for AVIO. All supported storage device types can share the same virtual SCSI MPT or AVIO adapter by specifying the same PCI bus and slot numbers. A virtual SCSI MPT or AVIO adapter can be added only to a virtual machine if it has a device connected to it.
Unlike real parallel SCSI bus, there is no arbitration on virtual SCSI buses. The SCSI target IDs for the virtual devices must be unique.The virtual SCSIMPT adapter takes target ID 15 for itself, leaving 0-14 for SCSI targets. All SCSI targets connected to a VM are single LUN devices. That is, virtual disks and DVDs are emulated as single LUNs and all attached devices are specified by per LUN VM Host systemfiles. The physical LUN number of an attached device has no impact. All virtual and attached SCSI LUN numbers are implicitly zero and therefore not specified. All supported storage device types can share the same virtual SCSI MPT adapter. Up to 15 storage devices can be added to the same SCSIMPT adapter by specifying the same PCI bus and slot numbers.
(From official documentation): You can achieve higher guests performance for HP-UX 11i v3 guests by configuring as many AVIO storage adapters as the number of virtual CPUs in the guest. The pcibus, pcislot, and scistgt portions need to be explicitly specified for each device. For example, a resource statement for a 4–vCPU guest takes the following form:
-a disk:avio_stor:1,0,0:disk:/dev/rdisk/disk1 -a disk:avio_stor:1,1,0:disk:/dev/rdisk/disk2 -a disk:avio_stor:1,2,0:disk:/dev/rdisk/disk3 -a disk:avio_stor:1,4,0:disk:/dev/rdisk/disk4 |

You can verify whether the autostart daemon is running with the following command:
host{root}# ps -ef | grep smh root 2034 1 0 Nov 3 ? 0:00 /opt/hpsmh/lbin/smhstartd root 1963 1939 0 13:33:30 pts/3 0:00 grep smh |
If the daemon is not running, you can start it from the HP-UX command line using:
host{root}# /opt/hpsmh/lbin/hpsmh autostart |
then use a web browser to navigate to http://host.domain:2301 or https://host.domain:2381.
You can also use the samweb command to automatically start the default browser in the main HP SMH page.
Remark:
If the autostart daemon is not configured (see the smhstartconfig -a off -b on), use the command /opt/hpsmh/lbin/hpsmh start instead to start the HP-UX Apache-based Web Server on ports 2301 (http) and 2381 (https).
