Record Type 22 (16) — Configuration

Record type 22 is written:

After every SMF initialization.
When any of the following operator commands are processed:
- CONFIG CPU
- CONFIG CHP
- CONFIG PFID
- CONFIG VF
- CONFIG STOR
- CONFIG ONLINE,S
- CONFIG OFFLINE,S.
When an ACTIVATE command or ACTIVATE function from a Hardware Configuration Definition (HCD) panel results in successful dynamic configuration changes.
When Asynchronous Operations Manager (AOM) attention-handling code is processing volume state change interrupts or when processing subsystem status change interrupts.
During pack-change interrupt processing, when the subsystem or originating device status has changed.

This record describes processor, channel path, storage in effect after the IPL or change. Record type 22 contains the current and previous status of the subsystem and originating device. The storage section contains 31-bit central storage addresses.

The length of record type 22 is variable. The maximum length of the type 22 record is 32,756 bytes. If the space required for data is such that the length would exceed the maximum length, one or more additional type 22 records are produced.
