Hi Tom, Thanks for the pointer to ipmiutil's code. I assume you found this comment:
--- /* ver 2 method: 2A 80 = P1_DIMMB1 */ /* SuperMicro says: * pair: %c (data2 >> 4) + 0x40 + (data3 & 0x3) * 3, (='B') * dimm: %c (data2 & 0xf) + 0x27, * cpu: %x (data3 & 0x03) + 1); */ --- I can definitely add it to my todo list. Would you mind writing up an issue on github here? https://github.com/chu11/freeipmi-mirror Al On Mon, 2018-12-03 at 17:55 +0100, Tom Hetmer wrote: > Hi, > > it'd be good if freeipmi supported decoding the supermicro ECC > errors. > > > Manufacturer: Supermicro > Product Name: X10DRH LN4 > eg. > freeipmi > 1,Dec-01-2018,06:37:53,Sensor #0,Memory,Critical,Uncorrectable memory > error ; OEM Event Data2 code = 3Ah ; OEM Event Data3 code = 81h > > > web interface > 1 | 12/01/2018 | 06:37:53 | Memory | Uncorrectable ECC > (@DIMMG1(CPU2)) | Asserted > > > something like this worked for me (stolen from ipmiutil) > > > $cpu = ($data3 & 0x03) + 1; > > > $NPAIRS = 26; > $rgpairs = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"; > > > $bdata = "0x".$data2.$data3; > $bdata = hexdec($bdata); > $pair = (($bdata & 0xF0) >> 4) - 1; > > > if ($pair < 0) $pair = 0; > if ($pair > $NPAIRS) $pair = $NPAIRS - 1; > > > $pair = $rgpairs[$pair - 1]; > > > $dimm = $bdata & 0x0F; > > > $dimm may be incorrect as the original code decrements 9, but on that > board it was wrong so i changed it to get the right result - we'll > see if it keeps getting the right values. > > Best, > Tom Hetmer > > > CDN77 Operations > supp...@cdn77.com / +44 (0) 20 3514 2399 / www.cdn77.com > > _______________________________________________ > Freeipmi-users mailing list > Freeipmi-users@gnu.org > https://lists.gnu.org/mailman/listinfo/freeipmi-users -- Albert Chu ch...@llnl.gov Computer Scientist High Performance Systems Division Lawrence Livermore National Laboratory _______________________________________________ Freeipmi-users mailing list Freeipmi-users@gnu.org https://lists.gnu.org/mailman/listinfo/freeipmi-users
