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.

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.
