Hi Bob,
Regarding my bonus question: I haven't found yet a definite answer if
there is a way to read the currently active controller setting. I
still assume that the nvsram settings which can be read with
service -d <arrayname> -c read -q nvsram region=0xf2 host=0x00
do not necessarily reflect the current configuration and that the only
way to make sure the controller is running with that configuration is
to reset it.
I believe that in the STK 2540, the controllers operate Active/Active
except that each controller is Active for half the drives and Standby
for the others. Each controller has a copy of the configuration
information. Whichever one you communicate with is likely required to
mirror the changes to the other.
I would assume the same. My question was more along the lines of "does 'service
read' read the stored config or rather the active config, or are the two always
the same".
Anyway, this subtle detail might not make a difference in most scenarios.
Nils
