GC (Group Configuration)

The GC command displays the configuration of the system at the time of the dump. It also displays the resources of the system and information about the I/O subsystem, including all the data link processors (DLPs), base-by-base, for all bases and DLPs configured at the time of the dump.

Syntax 

── GC ─┬──────────────────┬─┬──────────────────┬───────────────────────┤
       └─<simple address>─┘ ├─────┬─ OVERRIDE ─┘
                            └─ : ─┘

Explanation

The following text describes the meaning of each construct. Refer to “Basic Constructs” earlier in this section for information about the <simple address> construct.

GC GC <simple address>

Analyze as a configuration file the memory starting at the address of the descriptor located at the simple address. If you do not specify a simple address, DUMPANALYZER uses the address of the CONFIGURATION global descriptor.

GC OVERRIDE GC <simple address> OVERRIDE GC <simple address>: OVERRIDE

Analyze the memory area as if it were a configuration file whether or not word 1 of the memory area contains the word CONFIG (indicating a valid configuration). However, if word 1 does not contain the EBCDIC word CONFIG, DUMPANALYZER displays the following error message, unless you specify the OVERRIDE option: 

CONFIGURATION LOCATION MUST BE SPECIFIED

Example 1 

INPUT: MD G CONFIGURATION
    8024F(00000)  5 800030 C8B275

Entering GC or GC 8024F causes the configuration to be analyzed.

Example 2

The following example shows the GC command display and explains some of its terminology.

The following table describes the meaning of elements that commonly appear in the GC output:

Term

Meaning

PROC ID

A unique number identifying a host processor.

PATH

A description of the unique path from a host to a unit.

IOP

DEPENDENT HOST

A description of the outboard host in cases where a path to a unit or units is through an outboard host such as an NSP.
