Symptoms



 Gen6-noder som kjører OneFS-versjon 8.1.2 vil noen ganger generere diskutskiftingshendelser som viser at feil SLED-brønn må skiftes. Varselet viser riktig LNUM for disken som skal skiftes.

Eksempel:

  • Event generated by oneFS for Drive Sled A, Slot 1.

X - Disk Repair Complete: The following drive is ready to be replaced. Chassis Serial Number XXXXXX, Node 1, Sled A, Slot 1, Type HDD, LNUM 4.

  • However, Drive Sled A, Slot 1 is healthy and Drive Sled A, Slot 2 is Faulty.

1 Bay 2 /dev/da1 16 HEALTHY XXXXXX N/A
1 Bay A0 /dev/da3 14 HEALTHY XXXXXX A
1 Bay A1 /dev/da4 13 HEALTHY XXXXXX A >>>>>>>>>>>>>>>>>>> Healthy 
1 Bay A2 /dev/da13 4 REPLACE XXXXXX A >>>>>>>>>>>>>>>>>>> Faulty 

  • After replacement the resolved event will also generate for the wrong sled bay.

Resolved: Disk Repair Complete: The following drive is ready to be replaced. Chassis Serial Number XXXXXX, Node 1, Sled A, Slot 1, Type HDD, LNUM 4.

Cause

Det er funnet et problem i koden for generering av varsler som fører til at feil SLED-brønnummer rapporteres i varselet.

Resolution

Omgåelse av problemet:

  • Bruk LNUM som er angitt i varselet til å identifisere hvilken disk som skal skiftes. Som vist i eksemplet over, kan LNUM være tilordnet til en SLED og brønn ved hjelp av utdataene fra kommandoen «isi devices drive list».

Løsning: 

  • Dette problemet har allerede blitt løst i OneFS 8.2.0 og nyere, så en oppgradering av OneFS vil hindre at det skjer igjen. Isilons teknikere jobber for å løse dette problemet i en kommende rollup patch for OneFS 8.1.2.
