Chapter 8. Capacity upgrades

The On/Off CoD upgrade features are:
– On/Off CoD Active CP (FC 9897)
– On/Off CoD Active IFL (FC 9888)
– On/Off CoD Active ICF (FC 9889)
– On/Off CoD Active zAAP (FC 9893)
You may concurrently install temporary capacity by ordering On/Off CoD Active CP features
up to the number of current CPs, On/Off CoD Active IFL features up to the number of current
IFLs, On/Off CoD Active ICF features up to the number of current ICFs, and On/Off CoD
Active zAAP features up to the number of current zAAPs that are permanently purchased. In
other words, the upgrade configuration capacity is limited to the double of the current installed
capacity, for each individual processor type (CPs, IFLs, ICFs, and zAAPs).
Also, the total number of On/Off CoD Active zAAPs plus zAAPs cannot exceed the number of
On/Off Active CPs plus the number of CPs plus the number unassigned CPs on a z990
server. The sum of CPs, unassigned CPs, IFLs, unassigned IFLs, ICFs, and zAAPs cannot
exceed eight PUs per book. The number of zAAPs cannot exceed four zAAPs per book.
The CIU process will continue to bill for the upgrade on a daily basis until it detects the On/Off
CoD has been deactivated. When the temporary capacity is no longer required, its removal is
nondisruptive. If On/Off CoD is activated on a z990 server, other hardware upgrades/MES
are restricted. With the exception of memory and channels, LIC-CC enabled features, such
as CPs, ICFs, IFLs, and zAAPs, can be ordered but not enabled until the On/Off CoD upgrade
is deactivated.
The customer’s user will then be able to download and apply the upgrade using functions on
the HMC via the Remote Support Facility, without requiring the assistance of IBM service
personnel. Once all the prerequisites are in place, the whole process from ordering to
activation of the upgrade is performed by the customer. The actual upgrade process is fully
automated and does not require any on-site presence of IBM service personnel.
Additional logical processors can be concurrently configured online to logical partitions by the
operating system when reserved processors are previously defined, resulting in image
upgrades. The operating system must have the capability to concurrently configure more
processors online.
To participate in this offering, customers must have accepted contractual terms for On/Off
CoD (in addition to Customer Initiated Upgrade (CIU)), established a CIU profile, and installed
an On/Off CoD “right to use” feature on the machine. Subsequently, the customer may
concurrently install temporary capacity in any amount and use it for an indeterminate time.
The customer will be billed on a monthly basis. If the customer installs more than one On/Off
CoD order within a billing month, they will be billed for the greater of all orders installed within
that month. Monitoring will occur through the server call home facility and an invoice will be
generated if the capacity has been enabled for any portion of a calendar month.
The customer will continue to be billed for use of temporary capacity until they return the
server to the original state. After concurrently returning to the original state, the customer may
choose to activate a new temporary session that can be different from the previous session.
Note:
On/Off CoD provides a “physical” concurrent upgrade, resulting in more enabled
processors available to a server configuration. Thus, additional planning and tasks are
required for
nondisruptive
“logical” upgrades. See “Recommendations to avoid disruptive
