    Dear all, thank you for your help in advance.

     

    We have deployed a new DEL-EMC storage: VPLEX + XTrem IO as disk array.

     

    I have configured all in the array manager as documentation sais (http://documentation.commvault.com/commvault/v11/article?p=features/snap_backup/configuration/on_cs/t_snap_vplex_array_adding.htm). 

     

    Each time we try to make a backup using intellisnap, we have an error on the job. I have take a look at CVMA.log and I can see this failures:

    I am sure that the array is added (I have added and deleted it about 20 times today). Media agent has access to the array and to the VPlex in zoning and it's registered on both them (initiators are registered and working).
     
    What can be happening?
     
    Thanks a lot.

    Dear all.

     

    I have found a clue about my problem. I have deleted again the arrays and added one more time.

    My media agent is failing and not creating the necessary file for the python script.
     
    Any help about this?
     
    THanks a lot!
