HP-UX 11i v3 Read Before Installing or Updating, September 2008 (Update 3 Release)

What To Do
These operations can be performed using the Web GUI (HP SMH → Tools
→ Peripheral Devices) or the Command Line Interface using the
/usr/bin/olrad and /usr/sbin/insf commands.
If you do not use the sam/smh/pdweb TUI, no action is required. If you
want to use the TUI, download the latest PeriphDevWeb product (version
B.11.31.05 or greater) from http://software.hp.com. This product contains
the fix for the problem and the same will be included in the next OEUR
release for HP-UX 11i v3.
VxVM Not Supported On Systems With USB Devices At This Time
A message such as the following may be logged into dmesg during VxVM
operations:
"WARNING: VxVM vxio V-5-3-946 vol_disk_change_iopolicy: Public region
policy specific open failed for c0t2d0 0x5000020 ret = 0xffffffff"
These messages are logged when internal or external USB devices are
detected on the system and when the minor number of the USB devices
collide with any of the other storage disks connected to the system. This
results in the corresponding disks (disks that have same minor number as
that of the USB devices) not being able to be opened by VxVM.
In the above WARNING message, “open failed for cXtXdX” indicates
which disks will not function well under VxVM.
What To Do
No workaround exists for this problem at this time. HP and Symantec are
investigating possible solutions. Although the disks might work, the behavior
is unknown and not supported. VxVM is not supported on systems that
have USB devices connected at this point in time. This co-existence issue is
