hello, world\n I have this disk in an Icy Box connected via USB3: da0 at umass-sim0 bus 0 scbus11 target 0 lun 0 da0: <ST4000DX 001-1CE168 CC44> Fixed Direct Access SCSI device da0: 400.000MB/s transfers da0: 3815447MB (7814037168 512 byte sectors) da0: quirks=0x2<NO_6_BYTE> Every now and then (1 in 10 or so), when I power-up the Icy Box, the drive spins up, but the device nodes do not appear. I then try to "camcontrol rescan all", restart devd and devfs, but it has no effect. Invariably I end up power-cycling the Icy Box, which always works. Is there a different way to "re-probe" disks connected via USB when they fail to attach on the first try?
