Controller ViPR: L'ordine di rimozione di un file system NFS non riesce

[ERROR] Fri Jun 22 08:58:20 UTC 2018  Error 12000: Message: Operation failed due to the following error: Failure
Description: Check File System dependencies: NFS and CIFS exports and snapshots

ViPR Controller esegue query su VNX (CheckpointQueryParams XML API) per verificare la presenza di tutte le istantanee sull'intero array.

Se SnapSure non è abilitato o concesso in licenza sull'array VNX, la query API avrà esito negativo. Ad esempio:

Time on CS: Mon Jun 18 18:12:50 CEST 2018
Output from: /nas/bin/nas_license -list
key                 status    value
site_key            online    57 93 7c 7a
cifs                online   
nfs                 online   
replicatorV2        online

SnapSure è un prerequisito per ViPR Controller negli ambienti di file VNX. Per ulteriori dettagli, consultare la Guida ai requisiti e alle informazioni del data center virtuale del controller ViPR. 

 

1. Nell'interfaccia utente di Unisphere, selezionare il nome della control station.
2. Qui viene visualizzato il menu completo per il cluster VNX. A sinistra viene visualizzato il sottomenu delle licenze.
3. Verificare che la casella di controllo SnapSure sia selezionata. In caso affermativo, verificare che sia convalidato e, in caso contrario, convalidarlo.

Prima di eliminare il file system, ViPR Controller esegue una query su VNX (CheckpointQueryParams XML API) per verificare la presenza di tutte le istantanee sull'intero array.
