Stephen,

Here are the panic settings:

[gstronach at db2-www ~]$ cat /proc/sys/kernel/panic
60
[gstronach at db2-www ~]$ cat /proc/cmdline
ro root=/dev/vgSys/lvRoot panic=60

Yes to the BIOS (2.5.0) DRAC (1.45) BMC (01.33)

How would be the best way to do a console redirection to another machine
and log it to a file ?

Thanks for the help,
