Hi, I am thinking about adding an external Case with 4 haddrives to my server that should not be running 247. In ancient times this was done via SCSI and simply worked (turn on, rescan SCSI, mount). I already have an external drive connected via USB, but I am not able to read SMART using this link. x22# smartctl -a /dev/da0 smartctl version 5.37 [amd64-portbld-freebsd7.0] Copyright (C) 2002-6 Bruce Allen Home page is http://smartmontools.sourceforge.net/ Device: IC25N040 ATCS04-0 Version: CA4O (pass1:umass-sim0:0:0:0): MODE SENSE(06). CDB: 1a 0 1c 0 40 0 (pass1:umass-sim0:0:0:0): CAM Status: SCSI Status Error (pass1:umass-sim0:0:0:0): SCSI Status: Check Condition (pass1:umass-sim0:0:0:0): ILLEGAL REQUEST asc:24,0 (pass1:umass-sim0:0:0:0): Invalid field in CDB: Command byte 2 is invalid Device type: disk Can this be done with esata and a port multiplier in the box like this one: http://raidsonic.de/de/pages/products/external_cases.php?we_objectID=4239 I want to use software Raid via ZFS, so this should be a dumb chassis. Is anyone using a simliar configuration succesfully? Are port multipliers supported by FreeBSD? Do I need any special Sata-controller? Can I read SMART information? Regards, Michael!
