HP-UX 11i v3 Installation and Update Guide, March 2009 (Update 4 Release)

Table A-1 Known Install and Update Problems (continued)
Description/ActionProblem
When using crashconf, errors like this one may be seen:
# crashconf -r /dev/vx/dsk/DUMPDG/dumpvol
/dev/vx/dsk/DUMPDG/dumpvol: error: unsupported disk
layout
Additionally, after updating PA-RISC systems that previously used
older VxVM or HP-UX versions configured with VxVM dump
devices, errors like this one may be seen in syslog:
Apr 10 11:13:33 ptstn5 vmunix: ERROR: dump device
2:0x1 cannot be used and will be ignored:
What To Do
Do not use VxVM for dump devices. Any other disk or volume type
can be used. crashconf -r non-vxvm disk can be run to
replace the default swapvol (though not properly configured).
crashconf -s can be run to update the krs to use the new
non-vxvm disk as the default dump device instead of swapvol.
A patch to fix this problem, PHKL_38236, is available at HP IT
Resource Center site: http://itrc.hp.com.
