HP Smart Array 6404 controller query
There is, though, also a device file: /dev/ciss5 for the other 'half' of the controller which is doing nothing at present. I would like to know if it is possible to change the logical disk to span both halves (for extra resilience)? The instructions for the set up of the controller do not make this clear.
Many thanks.

Creates redundancy.
Disk shows up on ioscan and works?
Probably alternate path will too.

Re: HP Smart Array 6404 controller query
For extra resilience you might want to create a host-based mirror of logical disks, but what do you do if the SA6404's base module fails? That means you have lost access to the expander, too.
