RAID-5 disk pool creation with AIX

RNH4 asked
Last Modified: 2013-11-17
attempting to create a RAID -5 in a pSeries  9131-52A server.
Have 4 -  146GB drives, one has AIX 5.3 m O.S. loaded on it.
Is it possible ( and reccomended ) to create a RAID-5 set with 3 drives and one hot spare ?
Thus the O.S. drive being part of the RAID set.
I have mirrored the O.S. before but have not put it into a RAID set.
What would be the proper steps involved ?
Thanks Randy
