De switch is niet beschikbaar vanwege een kernelprobleem op MDS 9148S en MDS 9250i

Summary: Een 'sysmgr'-servicecrash leidt tot een kernelprobleem waarbij de switch niet beschikbaar is. De 'sysmgr'-servicecrash kan worden veroorzaakt door gebeurtenissen zoals het opnieuw instellen van het beleid voor hoge beschikbaarheid (HA) of andere systeemfouten. Een dergelijke gebeurtenis is echter geen routinematige gebeurtenis. ...

Cause

'sysmgr'-servicecrash vindt plaats op MDS 9148S en MDS 9250i platforms waarop MDS releases 8.1(x) tot en met 8.3(x) worden uitgevoerd. Dit leidt tot een kernelprobleem, waardoor de gehele switch niet beschikbaar is. Als gevolg hiervan moet het systeem krachtig opnieuw worden geladen om de functionaliteit te herstellen. Als gevolg van het kernelprobleem is het niet mogelijk om de exacte reden achter de beëindiging van de 'sysmgr'-service te bepalen.

Resolution

Oplossing:
Er is geen bekende tijdelijke oplossing om dit probleem op te lossen. Laad de switch echter opnieuw om de niet-beschikbare status te ontgrendelen. 

Resolutie:
De suggestie van TAC is om de code te upgraden naar versie 8.4 (2f).
