Error description

  • Spectrum Protect Plus Exchange backups will fail with 'Another
    IBM Spectrum Protect Plus agent process is using the VSS
    operation. Try again later" when running SLA policies
    concurrently on a single Exchange server.
    Currently, Spectrum Protect Plus does not allow multiple
    policies to run in parallel - some policies will time-out while
    waiting for a parallel backup to finish VSS (Volume Snapshot
    Service or Volume Shadow Copy Service) operations before it
    continues.
    The Spectrum Protect Plus Exchange backup job log shows:
    WARN,CTGGG1031,[EXCH-Host] Another IBM Spectrum Protect Plus
    agent process is using the VSS operation. Try again later.
    WARN,CTGGA1938,[EXCH-Host] Backup status was reported as
    partial.
    ERROR,CTGGA2336,Backup of all databases failed: Another IBM
    Spectrum Protect Plus agent process is using the VSS operation.
    Try again later.
    ERROR,CTGGA2073,Failed to perform backup of db instance
    EXCH-Host on application server EXCH-Host : null

Problem conclusion

  • In the backup job, SPP Exchange agent will try to acquire a
    global lock before the backup logic to synchronize the VSS
    operations. SPP Exchange agent will hold this lock until backup
    finished. So when a concurrent backup job launched, it will try
    to acquire the same lock and will fail.
    The SPP Exchange agent should acquire the VSS lock just before
    invoke VSS operation and should release it immediately after the
    VSS operation.
