No idea what's wrong with arcmsr, but >However, sd0 still says it's one sector, and: >scsictl /dev/scsibus1 scan any any >returns instantly without any change in the volumes. Scan attaches new devices, you probably need to detach sd0 first.
That works as expected on an amd64 system - I get the full 1 TB volume - but on the Alpha:
scsictl /dev/scsibus1 detach 0 0 sd0: detached ... scsictl /dev/scsibus1 scan any any sd0 at scsibus1 target 0 lun 0: <Areca, ARC-1110-VOL#00, R001> disk fixed sd0: 512, 59838 cyl, 68 head, 0 sec, 512 bytes/sect x 1 sectors Still just one sector :( John
