1. Controleer SEL-logboeken om te bevestigen dat er onherstelbare fouten op het knooppunt aanwezig zijn.

Opdracht: (Opdracht op afstand)

# sudo ipmitool -H <iDrac IP> -U root -P passwd -I lanplus sel elist

Opdracht: (Lokaal knooppunt)

# sudo ipmitool sel elist

Voorbeeld:

admin@node1:~> sudo ipmitool -H 192.XXX.2XX.107 -U root -P passwd -I lanplus sel elist

2. Controleer of er DIMM's ontbreken als gevolg van de gebeurtenis.

Opdracht:

# sudo dmidecode -t memory | grep "Locator\|Size" | grep -v "Cache\|Volatile\|Cache\|Logical\|Bank"

Voorbeeld:

admin@node1:~> sudo dmidecode -t memory | grep "Locator\|Size" | grep -v "Cache\|Volatile\|Cache\|Logical\|Bank"
        Size: No Module Installed <-- DIMM is missing
        Locator: A1
        Size: 16384 MB
        Locator: A2
        Size: No Module Installed
        Locator: A3
        Size: No Module Installed
        Locator: A4
        Size: No Module Installed
        Locator: A5
        Size: No Module Installed
        Locator: A6
        Size: No Module Installed
        Locator: A7
        Size: No Module Installed
        Locator: A8
        Size: 16384 MB
        Locator: B1
        Size: 16384 MB
        Locator: B2
        Size: No Module Installed
        Locator: B3
        Size: No Module Installed
        Locator: B4

Verzamel de uitvoer van de bovenstaande opdrachten en open een serviceaanvraag waarin wordt verwezen naar KB-215723 om te controleren of de DIMM van de server kan worden vervangen. 


Als de DIMM met succes is vervangen, moet voor xDoctor versie 4.8.92.0 of hoger het SEL op het getroffen knooppunt worden gewist. Verdere meldingen over deze logboekvermelding worden gestopt.

Voorbeeld - het systeemgebeurtenislogboek (SEL) wissen:

Voer een query uit op de iDRAC om het systeemgebeurtenislogboek op te halen en controleer of de fout aanwezig is in de uitvoer. 

Vergeet niet om, voordat u de SEL wist, te controleren op andere fouten die moeten worden aangepakt. Sla het logboek ook op in /var/log/hardware zoals beschreven in KB 49569te installeren.

In dit voorbeeld komt 192.168.219.101 overeen met het iDRAC IP-adres van knooppunt 1:

admin@provo~> ipmitool -I lanplus -H 192.168.219.101 -U root -P passwd sel list
   1 | 01/06/2022 | 04:34:58 | Event Logging Disabled #0x72 | Log area reset/cleared | Asserted
   2 | 02/03/2022 | 17:15:21 | Physical Security #0x73 | General Chassis intrusion () | Asserted
   3 | 02/03/2022 | 17:15:28 | Physical Security #0x73 | General Chassis intrusion () | Deasserted
   4 | 08/18/2023 | 01:44:01 | Memory #0x02 | Uncorrectable ECC (UnCorrectable ECC |  DIMMA1) | Asserted

  Wis de SEL: 

admin@provo:~> ipmitool -I lanplus -H 192.168.219.101 -U root -P passwd sel clear
Clearing SEL.  Please allow a few seconds to erase.

Controleer of de lijst is gewist:

admin@provo~> ipmitool -I lanplus -H 192.168.219.101 -U root -P passwd sel list
   1 | 08/30/2023 | 12:56:55 | Event Logging Disabled #0x72 | Log area reset/cleared | Asserted
