Error description
Per the original IBM Spectrum Protect for Virtual Environments 8.1 performance improvement design, the data mover should be able to process multiple VMs in parallel, multiple disks for the same VM in parallel, and use multiple sessions per VMDK. It also supports multi-session backup of a single VMDK. The internal algorithms figure out how many VMs are backed up at the same time, how many disks are backed up at the same time, and how many sessions are used to back up a single disk. But when performing concurrent backup using multiple VMDK disks in a single VM, only one disk is backed up at a time,even the controlling options VMMAXBACKUPSESSIONS, VMMAXPARALLEL, VMHOSTLIMIT, and VMDATASTORELIMIT are set to desired value. Example : Performance Options VMMAXParallel 25 VMLIMITPERHost 3 VMLIMITPERDatastore 25 VMMAXBACKUPSession 25 | MDVREGR 8.1.13 -TIV_5725TVEVM | IBM Spectrum Protect Versions Affected: IBM Spectrum Protect for Virtual Environments component Data Protection for VMware versions 8.1.13 and on Windows and Linux Initial Impact:Medium

Problem conclusion
Multiple session can be assigned to disks per VM. Parallel activity for VMDDKs is now working correctly.
