CUoD for processors
CUoD for processors can add, concurrently, more CPs, IFLs, ICFs, and zAAPs to a z990
server by assigning available spare PUs via LIC-CC. Depending on the quantity of the
additional CPs, IFLs, ICFs, and zAAPs in the upgrade, additional book(s) may be required
and can be concurrently installed before the LIC-CC enablement.
Figure 8-1 on page 190 is an example of CUoD for processors, showing the 8 PUs per book
that can be assigned as CPs, IFLs, ICFs, or zAAPs.
Figure 8-1 CUoD for processor example
An initial z990 server 2084-A08 (1 book), software model 304 (4 CPs) is concurrently
upgraded to a 2084-B16 (2 books), software model 309 (9 CPs). The model upgrade requires
adding a book and assigning and activating five PUs as CPs.
Note: The sum of CPs, unassigned CPs, IFLs, unassigned IFLs, ICFs, and zAAPs cannot
exceed 8 PUs per book. The number of zAAPs cannot exceed 4 zAAPs per book. The total
number of zAAPs cannot exceed the number of CPs plus unassigned CPs on a z990
server.
Important: CUoD for processors is not supported when CBU or On/Off CoD is activated
on a z990 server. CUoD for processors can be applied after the temporary capacity
upgrade via CBU or On/Off CoD is deactivated.
