Usually you will find the same messages in syslog and/or diagnostics (depending on type).

dmesg does not create a logfile.
Although some of the dmesg lines are logged to syslog.log during bootup, subsequent messages are not logged.

To create a log *and* add a timestamp, add this line to your crontab on *all* HP-UX boxes, any version:

# Monitor dmesg with timestamps
0,10,20,30,40,50 * * * * /sbin/dmesg - >> /var/adm/dmesg.log

The timestamp is added when dmesg - is run.

The "-" character tells dmesg to only display anything new since the last dmesg - command.
