Hi Kelvin ,

It could be volume group resides on the PV path /dev/dsk/c15t0d0 switched to alternative path /dev/dsk/c16t0d0 .

Please check the below things:

pvdisplay /dev/dsk/c15t0d0

Check whether the PV state is available and also do details analysis for this pV if your are gettings the issue repeatedly and also check the volume group health.

Thanks ,
Aneesh

0x1f0f0000 is a controller device c15t0d0, major number 31 that probably reset itself.

Verfiy that this is a controller with 'lsdev' command searching on 31.

Also attach this report:

/usr/sbin/cstm<<-EOF
runutil logtool
rs

This is fine. If you start getting over a hundred in a day then call HP.
