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
