HP-UX 11i v3 Installation and Update Guide, September 2009 (Update 5 Release)

Table A-2 Known install and update problems (continued)
Description/actionProblem
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 tracked by QXCR1000834043. VxVM will be
supported on systems that have USB devices once the fix for
QXCR1000834043 is available.

(841 of 1062).
What to do

without any problem once the update is complete.
