I want to tell the FreeBSD kernel to completely ignore a SCSI cam(4) device.# cat /var/run/dmesg.boot | grep '\<da1\>'ada0: 600.000MB/s transfers (SATA 3.x, da1 at umass-sim0 bus 0 scbus4 target 0 lun 1da1: <HP iLO LUN 01 Media 0 2.09> Fixed Direct Access SCSI-0 device da1: Serial Number 000002660A01da1: 40.000MB/s transfersda1: 1024MB (2097152 512 byte sectors: 64H 32S/T 1024C)da1: quirks=0x2<NO_6_BYTE># camcontrol devlist<ST1000DM003-1ER162 CC46>          at scbus1 target 0 lun 0 (pass0,ada0)<ST1000DM003-1ER162 CC46>          at scbus2 target 0 lun 0 (pass1,ada1)<HP iLO Internal SD-CARD 2.09>     at scbus4 target 0 lun 0 (pass2,da0)<HP iLO LUN 01 Media 0 2.09>       at scbus4 target 0 lun 1 (pass3,da1)I don't know what the da1 device is, nor do I want it visible on my system. FreeNAS sees this device and offers it as an option to create a volume on, which is not something I ever want to do.How can I accomplish this?Update: It appears this can be accomplished using device hints, setting the keyword disabled=1:hint.driver.unit.keyword=valueThe only problem is, I'm not sure how to specify driver and unit for this device.
