Recent refactoring of the BMC handler FSM introduced a code change that prevents the BMC Access alarm from being raised after initial BMC accessibility was established and is then lost. This update ensures BMC access alarm management is working properly. This update also implements ping failure debounce so that a single ping failure does not trigger full reconnection handling. Instead that now requires 3 ping failures in a row. This has the effect of adding a minute to ping failure action handling before the usual 2 minute BMC access failure alarm is raised. ping failure logging is reduced/improved. Test Plan: for both hwmond and mtcAgent PASS: Verify BMC access alarm due to bad provisioning (un, pw, ip, type) PASS: Verify BMC ping failure debounce handling, recovery and logging PASS: Verify BMC ping persistent failure handling PASS: Verify BMC ping periodic miss handling PASS: Verify BMC ping and access failure recovery timing PASS: Verify BMC ping failure and recovery handling over BMC link pull/plug PASS: Verify BMC sensor monitoring stops/resumes over ping failure/recovery Regression: PASS: Verify IPv6 System Install using provisioned BMCs (wp8-12) PASS: Verify BMC power-off request handling with BMC ping failing & recovering PASS: Verify BMC power-on request handling with BMC ping failing & recovering PASS: Verify BMC reset request handling with BMC ping failing & recovering PASS: Verify BMC sensor group read failure handling & recovery PASS: Verify sensor monitoring after ping failure handling & recovery Change-Id: I74870816930ef6cdb11f987424ffed300ff8affe Closes-Bug: 1858110 Signed-off-by: Eric MacDonald <eric.macdonald@windriver.com> |
