Managers,
I have a reduced raid set on a HSZ80 controller, with one of the disk
(DISK30900) having failed. Although two identical disks were available
in the SPARESET, the controller did not automatically pick up the spare
disk.
Here are some screen prints:

Manually, setting the replacement policy to NOPOLICY and trying to
replace one of the spare disks did not help either.
HSZ80:TOP>SET R5 NOPOLICY
HSZ80:TOP>Delete SPARESET DISK30300
HSZ80:TOP>set r5 rep=DISK30300
Error 3190: Unable to replace DISK30300 in R5
Am I missing something? Another anomaly that I have observed is that the
controller is unable to recognize the size of all the member disks of
the failed raid set. For e.g.
HSZ80:TOP>show DISK10900
Name Type Port Targ Lun Used by
------------------------------------------------------------------------

I will summarize.
