Determine o volume de instalação NFVIS-for-UC

Introdução

Este documento descreve as etapas necessárias para determinar em qual volume o NFVIS-for-UC está instalado atualmente.

Problema

É necessário determinar em qual volume o NFVIS-for-UC está instalado atualmente.

Solução

Etapa 1. Executar uma consulta à API do RedFish no CIMC do host para identificar quantas unidades virtuais existem por meio do https://<CIMC IP Address>/redfish/v1/Systems/<CIMC Serial Number>/Storage/MRAID/Volumes

Saída de exemplo

{
  "@odata.id": "/redfish/v1/Systems/SERIALNUMBER/Storage/MRAID/Volumes",
  "@odata.type": "#VolumeCollection.VolumeCollection",
  "@odata.context": "/redfish/v1/$metadata#VolumeCollection.VolumeCollection",
  "Description": "Collection of Volumes for this system",
  "Name": "Volume Collection",
  "Members@odata.count": 4,
  "Members": [
    {
      "@odata.id": "/redfish/v1/Systems/SERIALNUMBER/Storage/MRAID/Volumes/0"
    },
    {
      "@odata.id": "/redfish/v1/Systems/SERIALNUMBER/Storage/MRAID/Volumes/1"
    },
    {
      "@odata.id": "/redfish/v1/Systems/SERIALNUMBER/Storage/MRAID/Volumes/2"
    },
    {
      "@odata.id": "/redfish/v1/Systems/SERIALNUMBER/Storage/MRAID/Volumes/3"
    }
  ]
} 

Etapa 2. Consulte a API para cada volume, onde Number é o número do volume visto na saída da Etapa 1.https://<CIMC IP Address>/redfish/v1/Systems/<CIMC Serial Number>/Storage/MRAID/Volumes/Number

Exemplo de saída do VD-0

Etapa 3. Na captura de saída, o valor de DurableName para cada UUID.

"Identifiers": [
    {
      "DurableNameFormat": "UUID",
      "DurableName": "60027e370b077b003179502a9dc8b57a"  <<- This is the UUID you copy
    } 

Etapa 4. SSH ou conexão do console com o NFVIS-for-UC e executar o suporte show list-units | include Volume-UUID.

Etapa 5. O volume no qual o NFVIS-for-UC está instalado contém o dispositivo junto com as partições do dispositivo.

Exemplo de saída do volume com NFVIS-for-UC OS instalado.
