HP Integrity Virtual Machines Version 4.2 Release Notes

NOTE: Patch PHKL_37815 contains the new USB driver delivered with HP–UX 11i v3 (0903).
Consequently, if you install this patch on an HP–UX 11i v3 system that is older than 0903, you
might experience the same problem.
You can use a single hpvmdevmgmt to modify all guests to use the new USB DVD device. Run
the following command when all affected guests are off or not running:
/opt/hpvm/bin/hpvmdevmgmt -n gdev:old_USB_devicename:new_USB_devicename
The new USB DVD devices appear in the default ioscan command as follows:
usbmsvbus 0 255/0 mass_storage CLAIMED VIRTBUS USB Mass Storage
ext_bus 1 255/0/0 usb_ms_scsi CLAIMED INTERFACE USB Mass Storage SCSI
target 4 255/0/0.0 tgt CLAIMED DEVICE
disk 7 255/0/0.0.0 sdisk CLAIMED DEVICE HP
target 3 255/0/0.2 tgt CLAIMED DEVICE
disk 6 255/0/0.2.0 sdisk CLAIMED DEVICE HP DVD Writer 630c
For information about ioscan output for USB devices, see the Understanding HP-UX 11iv2 and
v3 USB ioscan white paper.
The following ioscan command gives you all agile device names for the DVD on the system.
Generally, there is only one that is either directly connected or connected using the USB controller:
ioscan -FN | grep DVD | awk -F: ‘{print "/dev/rdisk/disk" $13}’
For information about updating to the new USB driver on HP-UX 11i v3, see the Update to USB
Driver Support on HP-UX 11i v3 white paper.
2.3.2.3 HPVM-Guest Bundle on HP-UX Guests No Longer Reduces Value of dma32_pool_size
The HPVM-Guest bundle on HP-UX guests no longer reduces the value of dma32_pool_size.
Contact HP Technical Support for suggested values of dma32_pool_size, if necessary.
The HPVM-Guest bundle can be installed on physical Integrity servers where appropriate to
facilitate migration or cloning of that system image onto a virtual machine. When installed
directly onto a physical Integrity server, a warning is issued indicating that the bundle is intended
for use on a virtual machine. There is no known adverse impact resulting from its installation.
Users can configure dma32_pool_size to the value set when the V4.0 and V3.5 HPVM-Guest
software was installed, with the following command:
# kctune dma32_pool_size=4194304
The virtual machines must be rebooted for this setting to take effect.
2.3.2.4 Clicking Veritas Enterprise Administrator Link on the System Management Homepage
Might Result in VEA Abort and Core Dump
Starting with the September 2008 OEUR, clicking the Veritas Enterprise Administrator (VEA)
link on the System Management Homepage might result in VEA aborting and dumping core.
This problem happens when HP-UX has been configured to use large pages (64K base page size)
and VEA is bundled with a lower version of JRE.
This problem is also seen with VEA and the Integrity VM Host, as the Integrity VM default
configuration includes large page size for performance optimization.
To work around this problem, install the patch, PHCO_37694, which updates the version of JRE
without requiring a reboot. For availability of the patch, check the HP IT Resource Center site:
http://itrc.hp.com. For additional information about adjusting base page sizes, see the Tunable
Base Page Size information at: Tunable Base Page Size white paper.
