Re: [linux-lvm] LVM and multiple HBA ports




They way I have handled this is to use an md multipath device to combine the
two luns that are seen in to one md device, and then put lvm on top of
that.

Seems to work well - however testing 'real' failures rather than capable
pulling is somewhat more difficult/risky
