Redfishtool was introduced in CentOS for maintenance power control
and sensor monitoring. Both IPV4 and IPV6 addressing is supported.
The initial integration exposed an issue where square brackets were
required around the BMC IP address for IPV6 addressing. At the time
it was simpler to add the brackets for IPV4 as well.
redfishtool -S Always -T 30 -r [${BM_IP}] root
However, the python3 version of redfishtool, introduced in Debian,
rejects requests with square braces around IPV4 addresses.
redfishtool -v -S Always -T 20 -r [${BM_IP}] root
# Main: Error: rc=5
This update introduces a utility to the mtce msgClass module used
to distinguish between IPV4 and IPV6 addresses. The redfish request
create utility is updated to use this new utility when creating the
redfishtool request without adding the square brackets in Debian
for BMC's provisioned with IPV4 addressing.
Update testing revealed that the Debian based python3 version of
redfishtool takes a few seconds longer compared to the python2 in
CentOS. This exposes a timer race condition during sensor monitoring.
The BMC pthread is currently given 60 seconds to complete its
requests. However, unlike sensor monitoring using ipmi which uses
one request, redfish requires two requests.
Unfortunately, requests using the Debian python3 version of
redfishtool sometimes take longer than 30 seconds. If the cumulation
of both requests take longer than the current max timeout of 60
seconds then that is treated as a pthread timeout error condition
causing the hardware monitor to enter an error state for that host
which requires it to go through a full reconnection algorithm.
Given this additional issue this update also increases the BMC
thread timeout from 60 to 100 seconds to avoid needless reconnections
when using the mildly slower Debian python3 redfishtool.
