  • Tjek Cloud-licensen
    • Er den licenserede kapacitet nået?
       
Capacity licenses:

  • Kontroller konfigurationen
    • Er den korrekte cloudenhed angivet for MTree
    • Cloudenheden skal indstilles korrekt i DD. 
    • Sikkerhedskopieringsprogrammer kan ikke ændre den destinationsenhed, der er indstillet i DD.

  • Kontrollér status for dataflytning
sysadmin@dd4500 # data-movement status
Data-movement to cloud tier:
----------------------------
Data-movement is initializing..
Data-movement recall:
---------------------
No recall operations found.
  • Kontrollér status for oprydning i clouden
    • Cloudrensning og dataflytning kan ikke køre samtidigt
sysadmin@dd4500# cloud clean status
Previous cloud tier cleaning attempt was unsuccessful.
 Failure reason:
cloud unit "cloudunit2" did not have sufficient cleanable data.
Cloud tier cleaning finished at 2017/03/15 12:16:06.
  • Kontrollér logfiler
Fmig = File migration
  • Søg i ddfs.info logfiler efter dataflytningsposter. 
  • Søg efter "Fmig" i logfilerne omkring tidspunktet for dataflytningen, og kontroller rækkefølgen af filoverførselshandlinger.
