Hi, I have a WD My Book Pro Edition II external enclosure (2 drives inside) and I'm trying to put it in RAID1 mode on OBSD 5.4.
This is the enclosure: http://support.wd.com/product/install.asp?groupid=104&lang=en It supports RAID0 and RAID1. On Windows it is possible to switch between those with WD's software. No matter what you select though, OBSD always detects it as a RAID0: umass0 at uhub0 port 1 configuration 1 interface 0 "Western Digital My Book" rev 2.00/1.08 addr 2 umass0: using SCSI over Bulk-Only scsibus1 at umass0: 2 targets, initiator 0 ses0 at scsibus1 targ 1 lun 0: <WD, My Book Device, 108a> SCSI2 13/enclosure services fixed ses0: unable to read enclosure configuration sd2 at scsibus1 targ 1 lun 1: <WD, My Book, 108a> SCSI2 0/direct fixed sd2: 476936MB, 512 bytes/sector, 976764928 sectors "Western Digital My Book" rev 2.00/1.08 addr 2 at uhub0 port 1 configuration 1 not configured / # disklabel sd2 # /dev/rsd2c: type: SCSI disk: SCSI disk label: My Book duid: 52fa8b8b688d81e0 flags: bytes/sector: 512 sectors/track: 63 tracks/cylinder: 255 sectors/cylinder: 16065 cylinders: 60800 total sectors: 976764928 boundstart: 64 boundend: 976752000 drivedata: 0 Is it possible to use it as RAID1 and if so - how?
