it's not. you can manipulate DOS-style partitions under Solaris/SPARC
with fdisk(1M) too, but that's all. it's not for native slices.
format(1M) is for both SCSI and IDE drives, it doesn't matter on SPARC.
from manpage:
NAME
fdisk - create or modify fixed disk partition table
^^^^^^^^^^^^^^^
[...]
Note: Solaris/SPARC doesn't have "partition table", it has VTOC.
[...]
DESCRIPTION
This command is used to create and modify the partition
table, and to install the master boot (IA only) record that
is put in the first sector of the fixed disk. This table
is used by the first-stage bootstrap (or firmware) to iden-
tify parts of the disk reserved for different operating sys-
tems, and to identify the partition containing the second-
stage bootstrap (the active Solaris partition). The rdevice
argument must be used to specify the raw device associated
with the fixed disk, for example, /dev/rdsk/c0t0d0p0.
[...]
Create a partition
This option allows the user to create a new partition.
The maximum number of partitions is 4. The program
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
will ask for the type of the partition (SOLARIS, MS-
DOS, UNIX, or other). It will then ask for the size of
the partition as a percentage of the disk. The user
may also enter the letter c at this point, in which
case the program will ask for the starting cylinder
number and size of the partition in cylinders. If a c
is not entered, the program will determine the start-
ing cylinder number where the partition will fit. In
either case, if the partition would overlap an exist-
ing partition or will not fit, a message is displayed
and the program returns to the original menu.
