VTOC changes between Sol. 10 08/07 and 10/08 SPARC Install DVD

[Database Administrator]

Hi,

the virtual tabel of contents (VTOC) of the Sol. 10 08/07 SPARC
Install DVD
(prtvtoc output) was:

* /dev/rdsk/c1t0d0s0 partition map
*
* Dimensions:
* 512 bytes/sector
* 640 sectors/track
* 1 tracks/cylinder
* 640 sectors/cylinder
* 2048 cylinders
* 2048 accessible cylinders
*
* Flags:
* 1: unmountable
* 10: read-only
*
* First Sector Last
* Partition Tag Flags Sector Count Sector Mount Directory
0 4 10 0 6421120 6421119
1 2 10 6421120 373120 6794239
2 0 00 6794240 2560 6796799
3 0 00 6796800 2560 6799359
4 0 00 6799360 2560 6801919
5 0 00 6801920 2560 6804479
6 0 00 6804480 2560 6807039

I can see here 7 slices in sequentially order which can be read
separately
using dd.

dd if=s0 of=image.s0
6421120+0 records in
6421120+0 records out

The dd command reports the same number of sectors/blocks as prtvtoc.
The prtvtoc output of the Sol. 10 10/08 SPARC Install DVD is:

* /dev/rdsk/c0t0d0s0 partition map
*
* Dimensions:
* 512 bytes/sector
* 640 sectors/track
* 1 tracks/cylinder
* 640 sectors/cylinder
* 2048 cylinders
* 2048 accessible cylinders
*
* Flags:
* 1: unmountable
* 10: read-only
*
* First Sector Last
* Partition Tag Flags Sector Count Sector Mount Directory
0 4 10 0 5197440 5197439
1 2 10 0 5197440 5197439
2 2 10 0 5197440 5197439
3 2 10 0 5197440 5197439
4 2 10 0 5197440 5197439
5 2 10 0 5197440 5197439
6 2 10 0 5197440 5197439
7 2 10 0 5197440 5197439

This looks quite different to the older DVD VTOC. All 8 slices have
the same physical area and size on the newer DVD.
The DVD still contains the file .slicemap which contains the meaning
of the slices 2 - 6:

[...]
m 2 sun4c
m 3 sun4m
m 4 sun4d
m 5 sun4u
m 5 sun5us
m 6 sun4v

Is this slicemap file still valid? According to the VTOC we seem
to have only one physical slice on the new DVD.
If I read the first slice using dd I get

dd if=s0 of=img.s0
5197440+0 records in
5197440+0 records out

The numbers of dd and prtvtoc also matches here.
But the sizes of the dd output file and the ISO image
sol-10-u6-ga1-sparc-dvd.iso priovided by Sun are different:

img.S0: 2 661 089 280 bytes
ISO image: 2 661 416 960 bytes

The difference is 327 680 bytes (1 track = 640 * 512 bytes).
Can anybody explain this size difference?

I found in the meantime the following information:

Structure Change for Installation Media

Starting with the Solaris 10 10/08 release, the structure of the
Solaris Operating System DVD and Solaris Software - 1 CD have changed
for the SPARC platform. Slice 0 is no longer at the top of the
directory structure. Therefore, the structure of the x86 and SPARC DVD
and Solaris Software - 1 CD are the same. This change in structure
makes setting up an install server easier if you have a mix of
platforms, such as a SPARC install server and x86 media.

Where I can find more detailed information about these changes?

Ah, that's interesting news. It might make it easier, but with a
SPARC server the SPARC DVD can't be auto-mounted by vold. It either
fails to detect it as mountable or dumps core. It mounts the x86 DVD
correctly.
