According to the BMC log, the power information of PS1 and PS2 cannot be obtained.
Check the BMC logs of the nodes that have the alarm generated. It is found that the BMC was upgraded from version 240 to version 300.
The XH321V3 (node) power
information comes from the MM630 (management board). For the version earlier
than 272, the server nodes query and obtain the power and fan information from
the management board. For version 272 and later, the management board sends
power information to the server nodes. Therefore, if the node version is 272 or
later but the management board version is earlier than 272, the node cannot
obtain the power supply information.
Therefore, it is suspected that only the BMC version of the node is upgraded and the MM630 version is not upgraded. Therefore, you are advised to upgrade the MM630 version to V300.
