Memory self-healing on R630?
Here's an LC log message from a PowerEdge R630, BIOS 2.12.1, iDRAC 2.81.81.81:
2021-08-27T16:20:23+0100 MEM0702 Correctable memory errors detected for DIMM_A10.
Reboot the system to enable potential memory self-healing. Ensure BIOS is up to date. If problem persists, contact technical support for standard memory troubleshooting procedures.
Although 13G servers use DDR4, I wasn't aware the self-heal operations worked on this generation. Is the help text for MEM0702 accurate?
One thing I'd expect to see, if the self-heal actions are triggered, is something more in the log (e.g. MEM9060) stating that the operation worked, yet there is only the MEM0702 notice.
No Events found!

Memory self healing is supported with Xeon processor from 14th generation of PowerEdge server on wards. Looks like the error message is generic is not correct for 13th generation of server.
In 14th generation server, self healing messages (Success or fail) will be logged in LifeCycle Log. You can refer below link for more details on self healing and supported servers
