Hello.
i have a storageTek 2540 that was configured as Duplex.
controller B failed and then we restarted Controller A.
both didn't boot up.
we replaced controller A with a new controller before powering on controller A ,we removed faulty controller B
and powered on with only one controller in chassis.
the new controller A is booted up correctly and working , so we replaced controller B as well.
when putting controller B we get a blue light and its offline - we tried to re-seat it and its still the same
we checked on a different array and the controller is working perfectly(before that we tried a different controller the result the same).
how do i check if the configuration is duplex or a single controller?
anybody got an idea about why a working controller B gets a blue light(offline)?
thank you in advance.
