Failover in V6 what condition trigger a failover?

[To-M]

Actually even if you lose the Ping node you will not failover (being with the latest version of this years builds), you would need to lose the Ping Node and the AUX ports to have it failover. Another condition is if you have IO Errors from the controller or Array - this is noted on the releases notes, so if you have a RAID 5 and 2 drives fail this will cause a failover.

Hello,

thank you very much for the answer. Can you tell since which firmware version the aux connection is also used as a criteria for doing failover? Currently I run 6.0up95.xxxx.6156 2012-04-05 b6156 . The answer is quite important for me to correctly configure the ping node(s).

Have a nice day
Rainer

If we have more than 1 array, does the primary node failover on IO errors of ANY array?

There is an option for this in the GUI.... it is very visible when setting this up.

Trigger failover on I/O errors

React only for volumes configured in failover

Ah, yes, I see now.
Thank you for fast answer.
