DSECT NAME - IODSEC
FUNCTION - Map a Monitor record.
LOCATED BY -
Through the Monitor Control Area
REFERENCED CONTROL BLOCKS -
MRRECHDR Monitor Record Header
NAME - MRIODSEC
DESCRIPTIVE NAME - Monitor Event Record
Domain 6 - I/O Domain
Record 53 - Store Event Channel Report
DESCRIPTION - Indicates a Store Event Channel Report
NOTES:
- This record is generated when certain Store Event
channel reports are presented to the system.
- The content code field IODSEC_CSCRSCC indicates the
type of Store Event channel report that occurred on
the system.
- The reporting source ID field IODSEC_CSCRSRSI indicates
the channel-subsystem facility associated with the
event (Channel Path, for example)
- IODSEC_CALOFST1 should always be used to locate the
content-code-data associated with the Store Event
channel report. The content-code-data is unique
to the type of Store Event channel report that occurred.

Content Code data for Endpoint-Security-Status Update Notification (CC=15) This event signals that an endpoint-security-status update notification is signaled for the identified channel path and link. The Reporting Source field (IODSEC_CSCRSRS), the Reporting Source ID (IODSEC_CSCRSRSI), the Full-Link Address (IODSEC_CSCRFLA), the Full-Link-Address Extension (IODSEC_CSCRFLAX), and validity flags (IODSEC_CSCRSVF) are used to identify the channel path and link associated with the session for which the connection status has changed and byte 0 of the content-code-dependent field (IODSEC_CSCCSTAT) indicates the new connection status.

Content Code data for External-Key-Manager Information (CC=16) This event signals that the availability status of peer-node external key-manager has changed. The Reporting source field (IODSEC_CSCRSRS) contains a 0 value meaning the reporting source ID field (IODSEC_CSCRSRSI) has no meaning. Bits 0-7 of the Validity Flag (IODSEC_CSCRSVF) field are 0 indicating that the Full-Link Address (IODSEC_CSCRSFLA) and full-link-address extension (IODSEC_CSCRFLAX) fields have no meaning. The content-code-dependent data (IODSEC_CSCRSEKM) mapped below contains information about the external-key-manager.

Content Code data for Encryption-Key-Update Notification (CC=17) When the Reporting Source field (IODSEC_CSCRSRS) contains the value 0, this event signals a new encryption key has been established between this CPC and a peer node, which can either be a control unit or another CPC. Bits 0-7 of the validity Flag (IODSEC_CSCRSVF) field are zero, indicating that the Full-Link Address (IODSEC_CSCRSFLA) and full-link- address extension (IODSEC_CSCRFLAX) fields have no meaning, and bytes 0-7 of the content-code-dependent (IODSEC_CSCRSCOD) field contain the WWNN of the peer node (IODSEC_CSCWWNN). When the Reporting Source field (IODSEC_CSCRSRS) contains the value 4, this event signals that a new encryption key has been established between the identified channel path and the associated endpoint. The Reporting Source (IODSEC_CSCRSRS), the Reporting Source ID (IODSEC_CSCRSRSI), the Full-Link ADDRESS (IODSEC_CSCRSFLA), the full-link-address extension (IODSEC_CSCRFLAX), and Validity Flags (IODSEC_CSCRSVF) are used to identify the channel path and the associated endpoint.
