HP-UX Guests

Do not run live kernel debuggers inside a guest

Do not run tools that write kernel text, such as live kernel debuggers and performance tools such as kgmon and ktracer inside a guest. Under rare circumstances, these tools cause the guest to panic.

SCSI MPT driver upgrade required in HP-UX 0505 guests

For guests running HP-UX 11i V2 May 2005, HP recommends installing the Integrity VM guest management software in all guests, and upgrading the U320 SCSI MPT driver in the guests to Version B.11.23.03. Updating this driver enhances the performance and stability of the Integrity VM I/O subsystem. Failure to install the updated driver compromises the performance and stability of the virtual machines that run on the VM Host system. The HP-UX guest software depot is found in the VM Host directory /opt/hpvm/guest-images/hpux. To install the guest software, follow the instructions in the README file included in this directory.

The latest driver is available free of charge. You can access it through HP's Software Depot homepage. Search for A7173A and click on the “HP A7173A PCI-X Dual Channel Ultra320 SCSI Host Bus Adapter” link. The MPT driver is updated in HP-UX 11i V2 December 2005. Therefore, if the guest is running the December 2005 version of the operating system and later, it is not necessary to install the updated driver.

After downloading the driver, install the driver depot file using the swinstall command.

You should install the Integrity VM guest management software in the guest before you update the driver. If you update the driver before you install the guest management software, reboot the virtual machine after updating the driver. See the HP Integrity Virtual Machines Installation, Configuration, and Administration manual for information on installing the guest management software.

Do not use the iomap(7) command on HP-UX guests

The iomap(7) command allows you to map physical I/O addresses into the user process address space. Do not use this command on HP-UX guests.

iCAP commands fail on HP-UX guests

iCAP is installed as part of the HP-UX OS installation. A problem with HP-UX 11i V2 0606 and HP–UX 11i V2 0609 releases causes install-time configuration of iCAP to report failure with messages similar to the following:

NOTE:    Checking for partitionable system.
ERROR:   Software configuration has failed. After addressing the issues
         in the following output, configure this software with
         'swconfig B9073BA'.

These startup messages (which may appear in /etc/rc.log) may be disregarded.

iCAP commands cannot be used on virtual machines. iCAP commands are designed to work on the VM Host system.
