Arbitrator and ArbiQos products use the Linux bridge. As such you have the ability to turn on STP on the bridge and have two or more Arbitrator or ArbiQos machines running in parallel for a fail safe. STP is turned on by default in the newer versions of the APConnections products. To find out if your bridge has STP turned on or off just type in:
brctl show
To toggle it on or off use:
brctl stp my on
Believe it or not for the default timing of take over for failing of the primary bridge you don't have to do anything but start a second machine running on the same network within the same path as the primary machine. There are tweaks you can do to make the second bridge take over faster than about 40 seconds but that is beyond the scope of this doc. Please look up STP and Linux bridge via a search engine and you will find out more about it.
To get a system to reboot upon a panic put this into arbiext if running
an ArbiCD version or in some other startup file if you are using the GPL:
echo 10 >/proc/sys/kernel/panic
Some explanation on this:
kernel/panic - The integer value is the number of seconds the system
will wait before automatic reboot in case of system panic. A value of 0
means ``disabled''. Automatic reboot is an interesting feature to turn
on for unattended systems. The command-line option panic=value can be
used to set this parameter at boot time.
Arbitrator machines should not be panic'ing when the hardware and
software are correctly installed. We suggest you just use this as a
temporary fix until you find out if changing something in your hardware
configuration or in your kernel building is necessary to correct it.
