MSA 1000 shutdown of controller and fabric fail

[Craig Howe_1]

Hi

Couple of questions:

1.
What is the best way of shutting down an MSA 1000 controller (to test failover)?

I guess it is through the CLi? Can anyone tell me the command?

2.
I also guess that in an active/active config, if the fabric fails in the back, the working fabric will past requests to the non-preferred controller which will proxy these?

thanks

Craig

Hi,

I am not sure of the CLI command. But you could also disable the SAN port where the controller is connected. It is the multipathing software on the Hosts which will do the failover. MPIO (or whatever else you use for multipathing) will recognise that one path to its LUN is dead, and route I/O over the alternate path.

Regards,
Stephen

Hi

Thanks for the info.

Found that disabling a path only proxies the requests over the other controller.

Found a Cli command diasble this_controller or disabled other_controller will disable the controller to make it ready for removal.
