In gentoo you will use a qlogic card and just boot the box... the luns that are presented to the server will just show up as raw disk. If you want to get sexy with it, you multipath to set up dual channels to the same disk and round robin your access to those disks. This will require a bit more knowlege of the XRaid and how it presents storage, but it should be possible. If you are using a fiber switch you will want to create a zone from the device to the nodes based on the wwn that you get off the qlogic interface which should look something like this: $ cat /proc/scsi/qla2xxx/0 ... SCSI Device Information: scsi-qla1-adapter-node=200100e08ba84706; scsi-qla1-adapter-port=210100e08ba84706; scsi-qla1-target-0=50060482d52cead8; ...
