Okay... 4U Disk Enclosure, has 2 physical compute nodes, each physical compute nodes has 2 LSI 9211-8i controllers, so thats 4 total controllers across 2 nodes the box is enclosure is zoned and FreeBSD can see the following nodeA 16 daX devices 16 sesX,passX devices NodeB 16 daX devices 16 sesX,passX devices there are 32 disks in the box, so the numbers are good, however each LSI card only has a total of 8 SATA drives assigned to it hence 4 x 8 = 32 drives....... for gmultipath and zfs shouldnt each controller see 32 drives? or 16 drives for HA basically im thinking the enclosure shouldnt be zoned at all so each LSI controller can see every SATA drive, with gmultipath in the mix, i should be able to label 32 devices, and have both nodes recognize them... correct??? or am I chasing the rabbit down the wrong hole?
