I have HP ProLiant DL180 G6 server. I am getting such events in ipmitool sel elist:
  18 | 08/12/2021 | 15:46:21 | Power Unit PSRed Status | Redundancy Lost | Asserted
  30 | 08/12/2021 | 15:46:22 | Power Unit PSRed Status | Fully Redundant | Asserted
The events are always appeared in pair. Fully redundant is always the next second after redundancy lost. They are happening hot such often, but may be several times a week. The other servers are not showing any such events, so it is unlikely power problems in the rack.
Is it possible to determine which of two PSUs generates these events? Do I need to bother about them?
This is verbose sel list:
