## 13.3 IQD CHPIDs for Hypersockets 

This section describes the process to define IQD CHPIDs and their control units and devices. 

## 13.3.1 Defining IQD CHPIDs 

When Hypersockets must be defined, the CHPID type of IQD (Internal Queued Direct Communication) is used. Since z13, the IQD CHPID also requires the VCHID statement. The valid range for the VCHIDs are 7E0 - 7FF. 

As with 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 support only 1 CHPID; however, the CHPIDs can be spanned across multiple CSSs. 

A new IQD CHPID includes the following considerations: 

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, complete the following steps: 

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

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

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

4. In the Command line, enter add  (see Figure 13-57 on page 338) to add a new CHPID. 

5. Complete the following updates and press Enter: 

– Channel path ID  to F1 . 

– Channel ID  to 7C1 . 

– Channel path type  to IQD . 

– Operational mode  to SHR . 

– Description to the description that you want.
