We just received our first HP-UX 11.31 server. I'm only familiar with LVM on HP-UX 11.i where disk devices such as /dev/dsk/c0t8d0 were displayed in commands like "strings /etc/lvmtab" and "vgdisplay -v vg00", etc.
These commands now return /dev/disk/disk4_p2 instead, and I'm wondering how to correlate this to the output of ioscan and lssf /dev/dsk/* which shows the /dev/dsk/ctd numbers?
Any help would be appreciated.

In 11.31, the ioscan command got a lot of new options.
In this particular case,
ioscan -m dsf
is probably exactly what you're looking for.
Or if you want to map the new-style hardware paths :
ioscan -m hwpath

You should probably read through this white paper:
The Next Generation Mass Storage Stack HP-UX 11i v3
It should explain a lot of the new concepts that you haven't seen before.

Thanks Matti. Looks like things have changed a bit.
My goal was to see what disks are available before creating as OS recovery image using the 'drd clone' command.
# ioscan -m dsf
Persistent DSF Legacy DSF(s)
So I'm assuming c0t8d0 and c0t8d1 are separate disks. vg00 contains /dev/disk/disk4_p2 and a pvcreate of /dev/rdisk/disk3 ran without complaint.
