POWER5 and AIX 5.2

[Chapter11]

I have a POWER5 unit that is 2xVIO, and a metric ton of AIX 5.3 systems, all micropartitioned.

I have been asked to build an AIX 5.2 LPAR on it. The first problem I ran into, is that it seems that AIX 5.2 is not compatable with micropartitioning, so I dedicated a single CPU to it.

Now, all of my storage controller buses are allocated to either VIO servers (for virtual disks to the 5.3 systems), or to the backup partition so that lpar can hit the tape drives.

My AIX 5.2 install reports that it cannot find any disks, although the LPAR config has several virtual disks defined - I'm actually trying to do a new/complete overwrite over a working 5.3 system.

Am I correct in determining that not only must I dedicate a CPU to this, but I must also dedicate a storage controller (and therefore all of the disks/whatnot on that storage controller) to build an AIX 5.2 LPAR on a POWER5 unit?

And to follow that up, if I have no unallocated storage controllers, then it is impossible for me to build an AIX 5.2 LPAR on my POWER5, correct?

Virtual IO and/or SPLPAR needs AIX53.

p5 can run AIX52, but only dedicated CPU and IO.

so yes, you are correct on all counts.

One other thing: p5 requires at least 5200-04, but 5200-05 seems to run a lot smoother.
