How to Fdisk an IDE Solaris Sparkstation 5.

I looked in the "solaris, the complete referance" but it was not complete

It should be something like fdisk /dev/rdsk/c0t0d0s2 but that is the whole disk.  I do not like the automatic partions that solaris put on the disk with solaris 9.

I would like to view the slices.
I would like to write the new slices to the size I want.

        Run "format" as root. "format" is "fdsik" for Solaris. You can re-partition the disk.
    For more details, please do "man format".

       After repartition the disk, you need to run "newfs" to format (like format in DOS) it.

    For Solaris (SPARC) you need to use "format" -> partion to do the job as mentioned
    in Wesly's comment. (Solaris x 86, can use fdisk).

    You can use Solaris Software CD to boot up the system in single user mode, and then
    run "format" command to partion your HD, see:

    for more details.

    If you do fresh Solaris OS installation, you can choise "Customized" disk layout to
    partion your HD instead the default "auto" layout.

    When you install Solaris 9 from CD-ROM (Web Start), there are several options for disk layout.
    Select "manual layout", highlight "/dev/rdsk/c0t0d0s2" in next window and click "customerize".
    Put swap partition at the beginning (/dev/rdsk/c0t0d0s0) will have better performance since it is in the inner cylinder of hard disk. Besides, your /var partition should be bigger than (your memory size x 1.5) since your systme core dump file will put
    into /var/crash.
