## 8.1.3 Permanent upgrades 

Permanent upgrades can be obtained by using the following processes: 

GLYPH<SM590000> Ordered through an IBM marketing representative 

GLYPH<SM590000> Initiated by the client with the CIU on the IBM Resource Link 

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). 

## Permanent upgrades that are ordered through an IBM representative 

Through a permanent upgrade, you can accomplish the following tasks: 

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) 

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. 

## Permanent upgrades by using CIU on the IBM Resource Link 

Ordering the following permanent upgrades by using the CIU application through Resource Link allows you to add capacity to fit within your hardware: 

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
