Am I the only one using this SCSI card and ZFS? does anyone use any type of Adaptec U320 SCSI card? I hardly doubt the behaviour I'm experiencing is strictly related to ahd driver. When I first read about ZFS I've built up high hopes, but now they are slowly fading away. -Simon On Tue, 01 May 2012 21:31:20 -0400, Simon wrote: >ahd0: <Adaptec AIC7902 Ultra320 SCSI adapter> >on board of Super X5DPR-8G2+ motherboard. >Also would like to add that when I plug a drive into this running machine, it >prints the following, but does not come up under /dev unless I issue reset >using camcontrol. >ahd0: Someone reset channel A >(da0:ahd0:0:0:0): WRITE(10).
