Cause
L'arresto anomalo del servizio "sysmgr" si verifica sulle piattaforme MDS 9148S e MDS 9250i che eseguono LE RELEASE MDS da 8.1(x) a 8.3(x). Determina un errore grave del kernel, causando l'indisponibile dell'intero switch. Di conseguenza, il sistema deve essere ricaricato forzatamente per ripristinare la funzionalità. A causa dell'errore grave del kernel, non è possibile determinare il motivo esatto alla base della fine del servizio "sysmgr".
Resolution
Soluzione:
Non esiste una soluzione alternativa nota per attenuare questo problema. Tuttavia, ricaricare lo switch per rilasciare lo stato non disponibile.
Risoluzione:
Il suggerimento del TAC è quello di aggiornare il codice alla versione 8.4(2f).
