Vital product data  (VPD) Information that uniquely defines system, hardware, software, and microcode elements of a  processing system. Term Description 8.1.3 Permanent upgrades Permanent upgrades that are ordered through an IBM representative Permanent upgrades can be obtained by using the following processes: Tip:  The use of the CIU facility for a system requires that the online CoD buying feature  (FC 9900) is installed on the system. The CIU facility is enabled through the permanent  upgrade authorization feature code (FC 9898). Through a permanent upgrade, you can accomplish the following tasks: GLYPH<SM590000> Ordered through an IBM marketing representative  GLYPH<SM590000> Initiated by the client with the CIU on the IBM Resource Link GLYPH<SM590000> Add PU SCMs to the CPC drawer GLYPH<SM590000> Add Peripheral Component Interconnect Express+ (PCIe+) drawers and features GLYPH<SM590000> Add model capacity GLYPH<SM590000> Add specialty engines GLYPH<SM590000> Add memory GLYPH<SM590000> Activate unassigned model capacity or IFLs GLYPH<SM590000> Deactivate activated model capacity or IFLs GLYPH<SM590000> Activate channels GLYPH<SM590000> Activate cryptographic engines GLYPH<SM590000> Change specialty engine (recharacterization) GLYPH<SM590000> Add model capacity GLYPH<SM590000> Add specialty engines  GLYPH<SM590000> Add memory  GLYPH<SM590000> Activate unassigned model capacity or IFLs  GLYPH<SM590000> Deactivate activated model capacity or IFLs Consideration:  Most of the MESs can be concurrently applied without disrupting the  workload. For more information, see 8.2, “Concurrent upgrades” on page 287. However,  certain MES changes are non-concurrent; for example, CPC feature upgrades such as  from a z14 ZR1 Max4 to a z14 ZR1 Max12/Max24/Max30.  Memory upgrades are only concurrent when the required memory capacity is already  physical available (for example, by way of Plan Ahead Memory) and can be activated  through LICCC. Ordering the following permanent upgrades by using the CIU application through Resource  Link allows you to add capacity to fit within your hardware:  Permanent upgrades by using CIU on the IBM Resource Link 286  IBM 14 Model ZR1 Technical Guide
