Mount primary prtition. And first logical drive in an Extended DOS partition

If I have got this scenario hard disk has been prtitioned like below :

Code:

    |		      |                      |-------------- extended -------------|     

    | Windows c: 3 GB |Solaris partition 4GB |Linux ext2 |Linux swap | Windows d:  |

    |                 |                      |                       |             |

The easiest way to share data now is to do it through a FAT32partition. Solaris recognises it as partition of type pcfs.

It is specified as device:drive where drive is either the DOS logical drive letter (c through z) or a drive number (1 through 24).

Drive letter c is equivalent to drive number 1 and represents the Primary DOS partition on the disk; drive letters d through z are equivalent to drive numbers 2 through 24, and represent DOS drives within the Extended DOS partition.

mount -F pcfs device:drive /directroy-name

To mount the first logical drive ( d: ) in the Extended DOS partition from IDE0, in a directory /forum ,,,we use:

mount -F pcfs /dev/dsk/c0d0p0:d /forum.

If I want to mount c primary DOS partition FAT32, in a directory /thread,,,,,we use:

mount -F pcfs /dev/dsk/c0d0s0 :c /thread.

Why do I need to specifiy the p0 in the first mount while I have to specify s0 ?

I haven't mount a partition in Solaris and don't really know anything about it.

I am just curious that you are not expecting Solaris needs a mechanism to distinguish mounting a primary partition from a logical partition?

I am interested in your first mount statement as the Windows d: would have been regarded as the 3rd logical partition by both Dos/Windows and Linux but you have called it as the first logical partition in Solaris.

This link should give you the logic behind Solaris naming conventions.

Using p0:<drive> to access pcfs logical drives is the only documented way, using s0:<drive> or whatever may work (or not), but is not supported.

Does that mean I can use p0:<drive> in both cases d and c drives (Logical and primary) ?

Primary partitions are already specified with p<number>, no need to add a suffix to access them.
