    Is this maybe the inactive node of a cluster?

    I see this in bpbkar log:

    08:52:24.617 [956.1044] <2> ov_log::V_GlobalLog: INF - Failed to resolve volume path name
    08:52:24.617 [956.1044] <2> ov_log::V_GlobalLog: INF - Status E_FS_VOLUME_NOT_FOUND (0xE0000352) processing file path e:\fastsearch\\bin when getting file descriptors

     

    See this TN: http://www.symantec.com/docs/TECH128805

    Extract:

    Syntax:
    w2koption -backup -ignore_unresolved_volumes <volume:>
     
    Example if drive letter F is missing:
    w2koption -backup -ignore_unresolved_volumes F:
     
    Example if drive letters F and G are missing:
    w2koption -backup -ignore_unresolved_volumes F:G:

    Anything before 'Error bptm (pid=29453)...' in Job Details?

    Logs needed on the client: 
    bpfis and bpbkar

    Status 156 is a frequent error also being discussed a lot on Connect. Sp help should be available by searing for related issues in older threads.

    Hi,

            Enable open file backup  also increase the client logging to maximum and collect bpbkar logs . Logs are showing  Volume resolution error for (System State:\System Files\System Files) error . After collecting bpkar logs check whether netbackup is unable to resolve any path.

    About increasing logging i have raised it to General: 2, Verbose: 5. Is this OK? and now in new bpbkar logs how i will check whether netbackup is unable to resolve any path?

    Logging level is ok , also confirm whether you have enabled open file backup for the client. Then retry backup and collect bpbkar logs and post .
