IBM manual Automatic Enablement of CBU for GDPS, z890 Customer Initiated Upgrade CIU

needs of the larger CBU target machine. When capacity is needed in an emergency, the primary operation performed is activating the emergency CBU confi guration with the reserved PUs added into the confi guration as CPs.

Customers who have an active Remote Support Facility connection can perform a CBU upgrade automatically and within a matter of minutes, right from their CBU machine’s Hardware Management Console. For more information on how a CBU upgrade can be activated automatically, please refer to the z890 Capacity Backup Users Guide found on IBM Resource Link.

The z890 supports concurrent CBU downgrade. This func- tion enables a Capacity BackUp server to be returned to its normal confi guration without an outage (i.e. PowerOn Reset).

Automatic Enablement of CBU for GDPS

The intent of GDPS support for CBU is to enable auto- matic management of the reserved PUs provided by the CBU feature in the event of a processor failure and/or a site failure. Upon detection of a processor failure or site failure, GDPS will activate CBU to dynamically add PUs to the processors in the takeover site to acquire process- ing power required to restart mission-critical production workloads. GDPS-CBU management helps to minimize manual customer intervention and the potential for errors, thereby reducing the outage time for critical workloads from hours to minutes. Similarly, GDPS-CBU management can also automate the process of dynamically returning the reserved CPs when the temporary period has expired.

z890 Customer Initiated Upgrade (CIU)

Customer Initiated Upgrade (CIU) is the capability to initi- ate a processor and/or memory upgrade when spare PUs installed unused memory are available via the Web using

IBM Resource Link. Customers will be able to download and apply the upgrade using functions on the Hardware Management Console via the Remote Support Facility.

This unique and important function for zSeries gives the customer greater control and ability in adding capacity to the system to meet resource requirements for unpredictable e-business workloads and for applications which are dif-

ficult to size. CIU is a low-risk, well tested-and-tried facility for ordering capacity on demand.

On/Off CoD Testing

On/Off CoD has been enhanced to allow for a test at no charge for temporary IBM hardware capacity, IBM software, or IBM maintenance. This test can be used to validate the processes to download, activate, and deac- tivate On/Off CoD capacity nondisruptively. One free test per serial number can have a maximum duration of 24 hours commencing with the download and activation of an On/Off CoD order. This test can also be used as a train- ing session for personnel who are authorized to activate On/Off CoD. IBM continues to enhance On/Off CoD to help enable customers to become more adaptive to their on demand business requirements.

Order Staging for CIU-Express and On/Off CoD

All CIU-Express and On/Off CoD orders may now be staged for greater than 30 days. In fact, the orders may be staged for an extended period of time, unless one of the following conditions occurs:

•Order is canceled by customer

•Machine is no longer under warranty or IBM Mainte- nance Service Agreement

•Permanent PU and/or memory confi gurations is changed outside of CIU process
