The Qlogic driver (isp(4)) supports NPIV to some extent, but the firmware currently in the tree for the 8Gb cards at least doesn't seem to support multiple IDs: isp0: <Qlogic ISP 2532 PCI FC-AL Adapter> port 0xa400-0xa4ff mem 0xfb9b8000-0xfb9bbfff irq 16 at device 0.0 on pci3 isp0: non-MULTIID f/w loaded, only can enable 1 of 5 channels isp1: <Qlogic ISP 2532 PCI FC-AL Adapter> port 0xa800-0xa8ff mem 0xfb9bc000-0xfb9bffff irq 17 at device 0.1 on pci3 isp1: setting role to 0x1 isp1: setting role to 0x1 isp1: setting role to 0x1 isp1: setting role to 0x1 isp1: setting role to 0x1 isp1: non-MULTIID f/w loaded, only can enable 1 of 5 channels It is pretty much transparent to CTL when it is turned on, because it just looks like there are more frontend ports to CTL. The way you turn it on is setting the number of virtual ports like this in /boot/loader.conf: hint.isp.0.vports=4 hint.isp.1.vports=4 I did some testing with NPIV successfully a few years ago (2009), but I haven't done anything with it since. Matt Jacob probably knows more about the current state. Ken -- Kenneth Merry ken@FreeBSD.ORG
