I feel kind of guilty asking this, since I think it is simple but I searched the forum and could not find the answer.

Can someone please confirm that the following messages are related to two fibre channel boards on my Tezro complaining that I am not really using them:
Code:
/hw/module/001c01/IXbrick/xtalk/11/pci-x/1/1a/scsi_ctlr/0: Firmware version: 3.3.6: TP.
/hw/module/001c01/IXbrick/xtalk/11/pci-x/1/1a/scsi_ctlr/0: no cable detected.
/hw/module/001c01/IXbrick/xtalk/11/pci-x/1/1b/scsi_ctlr/0: Firmware version: 3.3.6: TP.
/hw/module/001c01/IXbrick/xtalk/11/pci-x/1/1b/scsi_ctlr/0: no cable detected.
/hw/module/001c01/IXbrick/xtalk/11/pci-x/1/2a/scsi_ctlr/0: Firmware version: 3.3.6: TP.
/hw/module/001c01/IXbrick/xtalk/11/pci-x/1/2a/scsi_ctlr/0: no cable detected.
/hw/module/001c01/IXbrick/xtalk/11/pci-x/1/2b/scsi_ctlr/0: Firmware version: 3.3.6: TP.
/hw/module/001c01/IXbrick/xtalk/11/pci-x/1/2b/scsi_ctlr/0: no cable detected.


Is there a way to disable these boards to get rid of these messages, since I don't plan to use the boards? It takes a while for my Tezro to work through these on start-up and I wonder if I can shorten the time.

Also, are these boards for connecting to disk arrays only, i.e. I can't connect two Tezros with these boards via some switch or directly? I went through the SGI fibre channel manual but it's old and says it is currently for connecting to disk arrays only. Just wanted to confirm.

Thank you.

Pull the boards out, do re-config then put the boards in anti-static bags and sell them to someone who actually wants them? (not me I have enough FC here)

You can connect the two Tezros to the same array, (or arrays using fibre switch such as a Brocade) and with CXFS software read and write to the same disks.

FibreChannel is sort of like SCSI... a bus for devices, if you want a communications system, you want something more like Gbit Ethernet.

Thank you for your reply. I think I will keep them, just in case.
So, I guess then there is no way to disable them from IRIX.
