ICOD - Can it deactivate cells/CPU's/memory - ?

Can installing ICOD deactivate cells/CPUs/memory that are currently active?

I am dreading the possibility of a reboot resulting in single-processor Dome partitions running on only one cell board with half of the PCI slots inaccessible!

Please advise....Thx

No - ICOD can NOT deactivate - It "Instant Capacity On Demand"....

You can move deactivate/re-allocate whole cell boards, not parts of them.
I've not done this on a superdome (coz I don't have one) but on an rp8400, where we move a cell board containing 4CPU's and RAM across to the other side.

# parstatus -C (shows you the boards

# parmodify -p1 -d3 (removes cell3 from partition 1)

A reboot is necessary

On other partition
# parmodify -p0 -a3:base:y:ri (adds this onto partition 0)

Have a good read of the man pages for these 'par' commands. You can also use 'parmgr' using GUI either from the command line, or using SAM.

Good luck.
