Here is how the disk appears under Linux :

total 0
lrwxrwxrwx 1 root root 11 12 déc. 13:38 ccw-0.0.1000 -> ../../dasda
lrwxrwxrwx 1 root root 12 12 déc. 13:38 ccw-0.0.1000-part1 -> ../../dasda1
lrwxrwxrwx 1 root root 12 12 déc. 13:38 ccw-0.0.1000-part2 -> ../../dasda2
lrwxrwxrwx 1 root root 12 12 déc. 13:38 ccw-0.0.1000-part3 -> ../../dasda3
The id 1000 is passed on to Linux by z/VM.
I understand that this id was used during kickstart's formatting, since
in our storage rack we now have a disk labeled 0x1000.
What I would like is to have this (3110 is the real physical address of
the disk) :
lrwxrwxrwx 1 root root 11 12 déc. 13:38 ccw-0.0.3110 -> ../../dasda
Is there to have it done by kickstart ?
It looks like you have the virtual address of the disk set to something
different than the real address of the disk. If you make the two match
in USER DIRECT, you'll have what you want.
However, it might be a better idea if you created full-pack minidisks
for the disks (that is, cylinders 1-END instead of 0-END or dedicating
the disk). That way, your storage team will have control of the actual
disk volsers, since Linux won't be re-writing them, due to not being
able to modify cylinder 0.
