Rebuilding a failed loadsource disk

Hi All,

After doing somebody a favour and exchanging a 0595 for a 5095 (wanted to
have everyting in the rack instead of racked CEC and tower EXP) i ended up
running around due to a failed load source drive (drive died when system
spun down and the dust removed), failed to do D-Type IPL due to a missing
7212 (seems it never got used after the initial setup)
I brought the drives to my lab, put them into an installed machine and
found the dead drive. I'm now rebuilding before moving those disks (and
controller) back to the original machine.
Here is my question:
What would be the SOP for rebuilding that disk, without having an
additional expansion with the same kind of slots and installed LIC? (found
out that moving from 520 CEC to 5095 is possible but not backwards, if 6
disks are present on a single cage, it dies with XXXX9023)
I haven't found a "rebuild disk drive" in the D-Type IPL...
I haven't tried it yet but i think SAS disks are exempt from the whole
ordeal since the SAS Controllers no longer care in which slot the LS is
(which may mean that it distributes the info...)
In any case, if i can find another way great and if not, i already have one
way.

Best Regards,

Roberto
