## 13.3.1 Defining IQD CHPIDs 

When needing to define Hypersockets, the CHPID type of IQD (Internal Queued Direct Communication) is used. Additionally since z13, the IQD CHPID also requires the VCHID statement. The valid range for the VCHIDs are 7C0-7FF. 

Like ICP CHPIDs, IQD CHPIDs are defined logically and internally to the processor and require no installed hardware (PCHIDs). However, from z13 a maximum of up to 32 high-speed virtual LAN attachments can be defined. 

Each of the logical IQD VCHIDs can only support 1 CHPID, however the CHPIDs can be spanned across multiple CSSs. 

The following are considerations for a new IQD CHPID: 

GLYPH<SM590000> Channel path ID (CHPID) 

GLYPH<SM590000> Channel ID (vCHID) 

GLYPH<SM590000> Channel path type 

GLYPH<SM590000> Operational mode 

GLYPH<SM590000> Description 

GLYPH<SM590000> Partition access list 

To define a new IQD CHPID, and provide access to a partition: 

1. From the main HCD panel, select option 1.3. Processors . 

2. Type s next to the Processor that you want to add a CHPID to, and press Enter . 

3. Type s next to the CSS ID that you want to add a CHPID to, and press Enter . 

4. In the Command line, enter add  (Figure 13-45), to add a new CHPID. 

5. Make the following updates and press Enter : 

– Update Channel path ID  to F0 . 

– Update Channel ID  to 7E0 . 

– Update Channel path type  to IQD . 

– Update Operational mode  to SHR . 

– Update Description to the description that you want.
