I suspect this to have been already answered a gazillion times in this forum. Anyway, a partition is what the BIOS call a primary partition and is limited to 4 while a slice is a subdivision of a Solaris/Solaris2 partition and you can have up to 8 or 16 ones depending on the architecture.
c = controller
t = target
d = disk

I always thought c=controller, t=target, d=disk, s=slice.
How exactly are they assigned? My internal drive is c0t1d0. But if I connect an external box, it jumps to c2t10d0, c2t11d0 etc. Is t=target? What exactly does those t-numbers mean and why does it jump to t10, t11 instead of going... (5 Replies)

NAME
cmdk - common disk driver
SYNOPSIS
cmdk@target, lun : [ partition | slice ]
DESCRIPTION
The cmdk device driver is a common interface to various disk devices. The driver supports magnetic fixed disks and magnetic removable
disks.
The block-files access the disk using the system's normal buffering mechanism and are read and written without regard to physical disk
records. There is also a "raw" interface that provides for direct transmission between the disk and the user's read or write buffer. A sin-
gle read or write call usually results in one I/O operation; raw I/O is therefore considerably more efficient when many bytes are transmit-
ted. The names of the block files are found in /dev/dsk; the names of the raw files are found in /dev/rdsk.
I/O requests to the magnetic disk must have an offset and transfer length that is a multiple of 512 bytes or the driver returns an EINVAL
error.
Slice 0 is normally used for the root file system on a disk, slice 1 as a paging area (for example, swap), and slice 2 for backing up the
entire fdisk partition for Solaris software. Other slices may be used for usr file systems or system reserved area.
Fdisk partition 0 is to access the entire disk and is generally used by the fdisk(1M) program.
