The Mtce Reinstall Handler can collide with the BMC Redfish audit resulting in reinstall failure. BMC handler's 2 minute connection audit can colliding with other BMC commands. The reinstall handler, with 4 bmc command operations is particularly suseptable. Two additional bmc communication improvements are implemented: 1. Add 'retry' handling to all BMC requests in the Maintenance Reinstall Handler FSM to handle transient command failures. Note: There are already retries to all but the power status query and the netboot requests in that handler and retries in other administrative commands that involve bmc requests. 2. Switch BMC power control command management from 'static' to 'learned' lists. Some BMCs don't support both graceful and immediate power commands; Graceful Restart and Force Restart. To remove the possibility of using an unsupported BMC command, this update switches from static to learned power command lists with log produced if a server is missing command support. Power commands escalate from graceful to immediate in the presence of retries. Test Cases: PASS: Verify bmc handler redfish audit is disabled PASS: Verify reinstall soak using redfish PASS: Verify reinstall netboot and power status retry handling PASS: Verify all power control commands using redfish PASS: Verify graceful operations are used if available PASS: Verify immediate operations are used for retries Regression: PASS: Verify bmc ping audit success and failure handling PASS: Verify Reset Handling soak (redfish and ipmi) PASS: Verify Power-Off/On Handling soak (redfish and ipmi) PASS: Verify Reinstall Handling soak (redfish and ipmi) PASS: Verify Standard System Install (redfish and ipmi) PASS: Verify AIO DX System Install (redfish and ipmi) PASS: Verify this update as a patch Change-Id: Idb484512ccb1b16e2d0ea9aff4ab7965347b1322 Closes-Bug: 1880578 Signed-off-by: Eric MacDonald <eric.macdonald@windriver.com> |
