I need to figure out the hard drive name for a solaris box and it is not clear to me what the device name is. On linux, it would be something like /dev/hda or /dev/sda, but on solaris I am getting a bit lost in the partitions and what the device is called. I think that entries like /dev/rdsk/c0t0d0s0 are the partitions, how is the whole hard drive referenced?

/dev/rdsk/c0t0d0s0 means Controller 0, SCSI target (ID) 0, and s means Slice (partition) 0.

Typically, by convention, s2 is the entire disk. This partition overlaps with the other partitions.

prtvtoc /dev/rdsk/c0t0d0s0 will show you the partition table for the disk, to make sure.
