13.3 IQD CHPIDs for Hypersockets 13.3.1 Defining IQD CHPIDs This section describes the process to define IQD CHPIDs and their control units and devices. 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: To define a new IQD CHPID and provide access to a partition, complete the following steps: 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 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.
