Will doing an fdisk to toggle the bootability mess up my partitions?
I get this when I try the fdisk:
# fdisk /dev/dsk/c0t2d0s0
fdisk: Cannot stat device /dev/dsk/c0t2d0s0.
Any ideas will be gratefully appreciated

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.
