Re: how to wipe entire system and reload with new hardware configuration

Chris:

Was this system LPARd?  Otherwise the load source on the CEC can only be 
in one of two places,  Slot 2 or 3 of the right hand DASD chassis with 
the internal controller.  So.....

First bring up the HMC and create a new LPAR with ALL of the equipment 
on it.
Set the load source to the internal controller, it will look something 
like: U787F.001.DPM2BWR-P1-T10
Set the console up as your HMC.
In the settings for the new partition set the IPL source to D and the 
Keylock position to Manual, and put the CD in the drive.
Activate your new partition

When LIC finally loads you'll have the option to initialize the system.  
Pick that one.  That will clear all of the disk you have on the system.

DO NOT LOAD the OS YET!

Deactivate the partition.  You can just kill it from the HMC.

Disconnect all your 0595s etc. so you only have the CEC left.

Go back to your HMC and delete the all the partitions.  (you could also 
just remove all the now missing hardware from the profile but that's too 
much like work)

Create a new partition using all the hardware and set your load source 
up just like you did before.  The LIC is still there.  IPL into the A 
side, manual and finish your OS install, including initializing your 
disk and starting the RAID set or starting mirroring.

Lots of time involved.  Get large bag of chips and a good book to 
read.......( not that Larry or I have EVER done anything like this 
before....)
