Re: EVA5000 and host connections settings
If you run it against an active/passive EVA you can *C-R-A-S-H* the EVA !!

Re: EVA5000 and host connections settings
Then I thought the ESX severs would use only one port for all i/o traffic.

Re: EVA5000 and host connections settings
If you use multiple ESX servers with "fixed" on an active/passive array, there is a high change that you get "path thrashing" when one server experience a failure on its active path.

Re: EVA5000 and host connections settings
If the active path fail, the other hba can do i/o to the same EVA controller through the other EVA port on the same controller, so I don't understand how this can cause path trashing.
