Channel path identifier (CHPID) summary report

The Channel Path Identifier (CHPID) Summary Reports list the channel path identifiers defined in each CSS in the IOCDS. The report name in the heading states which CSS is being reported and to which CSS the CHPID numbers belong. Every defined CSS is reported separately. For each CHPID, the report shows the following:
  • CHPID number of the channel path
  • PCHID number, PCHID and PORT numbers, VCHID number, or AID and PORT numbers associated with the channel path. VCHID numbers are indicated by '(V)'.
  • Channel path type
  • Switch number associated with the channel path
  • Channel path parameter (CHPARM)
  • Logical partition (LP) access method for the channel path
  • MIF image ID numbers of logical partitions that the channel path can access.

Figure 1 shows an example of the CHPID Summary Report.

If the SWITCH keyword is not allowed for the channel path type, the report column contains N/A. If the SWITCH keyword is allowed but not specified for a channel path, then the report column contains NONE.

If the CHPARM keyword is not allowed for the channel path type, the report column contains N/A. If CHPARM is allowed but not specified or has a value of 00, either NONE or 00 is shown, depending on the channel path type.

The LP ACCESS report column shows the logical partition access method for the channel path.
  • DED is reported if the channel path is dedicated to a single logical partition
  • REC is reported if the channel path is defined as reconfigurable
  • SHARED is reported if the channel path is defined as shared
  • SPANNED is reported if the channel path is defined as spanned.
The MIF IMAGE ID NUMBERS report column shows the MIF image IDs of logical partitions that the CHPID can access in the CSS.
  • For each partition in the access list of the CHPID, the MIF image ID number column contains an A for the corresponding partition.
  • For each partition in the candidate list but not the access list of the CHPID, the MIF image ID number column contains a C for the corresponding partition.
  • For all partitions not in the access or candidate lists of the CHPID, the corresponding MIF image ID number columns are left blank.

Several legends are located at the end of the CHPID Summary Report. The first set of legends describes the entries in the CHPARM report column for the channel path types that support the CHPARM keyword. The last legend describes the entries in the MIF IMAGE ID NUMBERS report column.

At the end of the CHPID Summary Report, the totals are listed for each channel path type your CPC supports in the CSS.
