Solaris 10

hmmm...how can i format a disk ?

i have a disk at c0t1d0, and its an old linux disk, i thought i could just to the following to format the entire disk, to remove every parition...


command format -> select disk -> format.

If i then save, and reenter, and type partition->print i see that the partitions still are there. isnt there any fdisk command, if i type help under the format command, i cant see any fdisk command.

To create or delete primary partitions, the command is /usr/sbin/fdisk.

can you do the same with format, or do i have use fdisk to create and delete pri partitions ?

What is the regular way to format and create 1 partition, is it

format->partition->select (and choose 1 partition here, ex slice 7, and use all the space here)
label->quit ---> newfs /dev/dsk/<disk> ?

Partitions and slices are different beasts.

Can you clarify which ones you want to delete ?

i thought partitions and slices where the same thing ?

The thing i want to do is really simple to describe

I have a linux disk, with 3-4 ext3 partitions.

1. I want to delete all the partitions on that disk (wipe it clean)
2. Create 1 large partition of the whole disk size
3. Format that partition with ufs
4. Mount the partition

Partitions in the Solaris on x86 terminology are only one of the 4 primary partitions of a disk, plus extended partitions which are only supported for FAT.
partitions names end with p1, p2, p3 or p4, there is also p0 which means the whole disk, and p0:x which mean an extended partition.
One of the primary partitions can be of Solaris or Solaris2 type.
This partition is subdivised in areas called slices, which are sometimes called partitions on SPARC.
Their names end with s0, s1, s2, ...
By convention, s2 is a slice representing the whole size available, and shouldn't be changed.

You manage partitions with fdisk, and slices with format/fmthard/prtvtoc.

Okay, use fdisk to set a single partition spanning the whole disk, then use format to create a slice 0 with all space available.
