Here is relevant output from dmesg. ahc0: <Adaptec 2940 SCSI adapter> port 0xf400-0xf4ff mem 0x2000000-0x2000fff irq 10 at device 14.0 on pci0 aic7870: Wide Channel A, SCSI Id=7, 16/255 SCBs ahc1: <Adaptec 2940 SCSI adapter> irq 0 at device 15.0 on pci0 ahc1: can't allocate register resources ahc1: Platform free device_probe_and_attach: ahc1 attach returned 12 This seems to indicate that it can find both drives, but that ahc1 is not part of the system, right? I apropos'ed 'filesystem' and found a function, VFS_START, that seems relevant to making a filesystem, but I doubt this is what I'm looking for. I'm pretty sure that the second disk isn't mountable because camcontrol devlist returned this: <IBM DCHS04U 2929> at scbus0 target 0 lun 0 (pass0,da0) I'm still trying to digest the man pages for vinum. I've looked in the handbook at http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/raid.html but it only describes ccd. Right now I'm just trying to figure out exactly what state the second disk needs to be in, in order to use it for redundant storage. Can anyone make a suggestion about this or maybe another resource for this? Jim __________________________________________________ Do You Yahoo!? Make a great connection at Yahoo!
