PowerFlex Manager – SO-nodeopdatering mislykkes i funktion update_clc_node_agent

Scenarie

• Miljø: High-Available (HA) CloudLink Center-enheder
• Problem: SO-ressourcegruppen viser kun én af de to forventede CLC-VM'er.
• Symptom: Opgradering af SO-noderne mislykkes med henvisning til, at noden ikke er i PMM.

Dette scenarie repræsenterer det udløsende punkt for opgraderingsfejlen. Nedenfor er et eksempel på, hvordan en sund stak skal se ud, når du kører update_clc_node_agent funktion:

Desuden registrerer opgraderingsjoblogfilerne det præcise tidspunkt, hvor opgaven mislykkes:

Påvirkning

Kan ikke opgradere SO-noder.

Logfilerne angiver, at PowerFlex Manager ikke kan fortsætte med den update_clc_node_agent opgave, da den ikke identificerer den korrekte "Primære" blandt de to CLC-enheder. Hvilket vises i deployment.logs på fejllinjen:

ERROR [2024-12-19T13:35:51.093230] 19552: service_deployment.rb:5535:in `process_firmware_update': Encountered an error during firmware update: NoMethodError: undefined method `[]' for nil:NilClass

1. Forsøg en handling med oplysninger om opdatering af tjeneste 

   1. Start handlingen Update Service Details på den berørte tjeneste.

2. Bekræft lageroversigten i guiden

   1. Under processen bør guiden vise en lageroversigt, der angiver, at en CLC-enhed fjernes, og en anden tilføjes.
   2. Dette bekræfter, at den aktuelle CLC ikke er den primære, og at den enhed, der tilføjes, er den korrekte primære
       

3. Fuldfør processen med oplysninger om opdateringstjenesten

   1. Afslut handlingen Opdater tjenesteoplysninger som anvist i guiden.

4. Fortsæt med opgraderingen

   1. Prøv at opgradere igen. Det skulle nu fortsætte uden problemer.

Påvirket version
