Amplifying what Mr. Deen wrote:
After you boot from CDROM, you will need to look at the
script 'ia_install', where it calls 'ft_get_size'. Follwing
thru a couple of levels you will see where it compares the ID
read from the hard disk to the entries in it's data base.
The trick is to a) make it look somewhere else for that disk
partition map (not in a CD based file) and b) to provide
partition information which satisfies IA.
You can copy scripts/files to directory '/tmp' and edit them
there; that directory is created in processor memory during
the boot up, and is the only one which can be written.
You will need to copy 'ia_install', 'ft_get_size' and
one or two others, then modify a couple of them. You will
change them to provide a new partition map. You will also
make changes to cause them to run from the '/tmp' directory
thru the part of the process which sets up the disk partitions,
then run from the CDROM for the remainder of the installation
process.
When creating the partition map for the new disk size remember
to look at another one first. Sizes of partitions other
than /opt are important. If they are made too small, IA won't
run very well. Other partition maps give you a guide to the
required sizes. '/opt' can be expanded or shrunk to get the
other sizes right.
For information about this process, read up on the Sun
command 'format'. It is the tool used to get the Disk ID
string, and to set the partition sizes.
Also, you should probably make a copy of the modified
scripts and files to diskette when you've changed them, so
the process will be easier the next time. Remember that when
the reboot occurs during the installation process these files
(which are in the main memory directory '/tmp') will be lost,
so get them before that reboot.
There is a diskette labeled "Pre-Release Install" K0175SN-F which
does this stuff for a 36 GB disk. If you have a copy, it may give
you a little help sorting thru the process.
Best of luck.
