Yes, /dev/dsk/cXtXdX and /dev/rdsk/cXtXdX are device nodes, which are essentialy magic pointers to the devices itself, through which the communications with the driver hapeen, and represent either disk, or partition/slice (the last two characters may represent the partition, p0 ? whole disk, p1 ? first partition).
To see the disk devices available, you can use prtpart program from the console, e.g ~ % pfexec prtpart Available disk devices: /dev/rdsk/c8t0d0p0 /dev/rdsk/c8t1d0p0 Show that I currently have two disks, c8t0d0p0 and c8t1d0p0. You can use a "format" command as well (no kidding, it is actually called that): ~ % pfexec format AVAILABLE DISK SELECTIONS: 0. c8t0d0 <DEFAULT cyl 12164 alt 2 hd 255 sec 63> /pci at 0,0/pci1043,81ec at 1f,2/disk at 0,0 1. c8t1d0 <ATA-WDC WD1500ADFD-0-7QR5-139.74GB> /pci at 0,0/pci1043,81ec at 1f,2/disk at 1,0 ... I'm sure that the second disk will show up this way, and you'll be able to use it to create zpool on it. Cheers, Einar.
