SolutionIt sounds like you did exactly what needs to be done. I'm adding memory to a cell on a SD tomorrow, and that is exactly the procedure that I am going to follow. I'll let you know what happens....

Re: Cell Power Board Replacement on PA8800 SuperDome
Ron, I did the two memory upgrades this morning. Both were similar to your situation, in that I was taking out a cell board from a single cell partition. After the OS was completely down, I PE'd the cell OFF, pulled it and did the memory upgrade. The first went smoothly. The second one did NOT. None of the lights on the cell came back on when I slid it back into the complex, they should come on immediately even with the cell slot PE'd off. I got the same "unavailable" message and was unable to PE the slot. I reseated the cell and the lights came on like they should. I could PE the cell, and it booted normally. I can only think that this is a seating issue. Possibly a hang on the backplane, but it shouldn't have cleared itself if that were the case. The cluster is back up and all packages are running. I hope you're having the same kind of luck!
Good Luck - Tim

Re: Cell Power Board Replacement on PA8800 SuperDome
something like this could happen if you do not follow the correct procedure to unmount and remount the cellboard.
The cellboards are not intended as customer replacable units (CRUs) and only trained people should replace the components that are not CRUs.
The cellboard must not plug fully into the backplane before the powerboard have been attached, otherwise 48 V are going through a cell without a powerboard and strange things could happen to this Slot. A full powercycle is needed to get the cell slot back to life.
Please call the HP support center for additional details or better ask a Superdome trained engineer to do the upgrade.
I hope this helps
Stefan
