Good morning/afternoon/evening (gotta cover my bases on that one) everyone.

I'm getting ready to undertake an upgrade of my experimental system (read
that I can burn it down and start over - we're not in production) from the
2.2.x SuSE distribution to the 2.4.x version available by FTP currently on
the SuSE web site.

I have a couple of issues, and I would like to know the best way to
undertake this.

1) I don't believe I'm formatted in a CDL layout, which I understand to be
necessary in order to have S/390 side tools back up the volumes.
2) I am not sure what physical devices are currently what dasda,b,c,d etc.
devices in the Linux environment.

My FSTAB looks like this:

/dev/dasda1     swap                      swap            defaults   0   0
/dev/dasdb1     /                         ext2            defaults   1   1
/dev/dasdc1     /usr                      ext2            defaults   1   2
/dev/dasdd1     /tmp                      ext2            defaults   1   2
/dev/dasde1     /FileServer               ext2            defaults   1   2

none            /proc                     proc            defaults   0   0

What I am not remembering the location of, or command to interrogate, is
the device numbers I can 'see'.

I theoretically have enough disk not in use to copy each of these devices
to  a CDL formatted disk, however I won't be absolutely sure that I do
until I check the device numbers I have allocated. It should not be a
problem but I can't quite tell.

Anyway, once I find that out my plan is this:

format the 'spares' in CDL layout - To do that I would really be happy as a
clam if someone could tell me the correct command to do that.

Then, unless I am mistaken, using the ramdisk system with all disks
mounted, I should be able to use the DD command to dump volume a to volume
b correct? Are there any issues of dumping from one disk layout to another,
if the volumes are the same size?

Thanks for any help or insight on this you much more knowledgeable people
than I, might have.
