    SM_lun_mismatch - Associated volumes not found on specified host

      Hi,

       

      Windows 2012r2 hyper V cluster, Nimble cs235 version 3.4 with newest Windows connection client.

      Using Veeam backup version 9.

       

      I have 1 specific virtual host where on of its drives is placed on a volume named VM-DataDisk. Each time Veeam has to do a backup with VSS provider (Nimble or Microsoft, it fails as it cannot create snapshot.

      Looking in the Nimble log, I see:

          Exception info:

      { Message Code: SM_lun_mismatch,  Level: ERROR,  Text: [Associated volumes not found on specified host.] }

       

      So Nimble is complaining about associated volume (VM-DataDisk) is not found the specific host - where the 3 other volumes is detected and snapped - and i guess thats why Veeam fails to use VSS backup.

       

      Question: Is this a Nimble or Veeam issue?
