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.
