Error description
IBM Spectrum Protect for Virtual Environments - Data Protection for VMware version 8.1.11 uses new functions of the VMware Virtual Disk Development Kit (VDDK) to process only the changed data blocks for a guest VM. As a requirement for above process to work correctly, the disk size must be a multiple of 2048 sectors (1 MB). If that condition is not fulfilled, the following error will be seen : ANS0361I DIAG: ..\..\common\vm\vmbackcommon.cpp(7946): vmOpenVirtualDiskForBackup(): error opening vmware VMDK: disk id=0, rc=109. ANS4174E Full VM backup of VMware Virtual Machine 'VM_name' failed with RC=109 mode=Incremental Forever - Full, target node name='VM_DC', data mover node name='VM_DM' ANS1228E Sending of object 'VM_name' failed. ANS1062E Only a single image may be selected when a destination is entered. IBM Spectrum Protect Versions Affected: IBM Spectrum Protect for Virtual Environments - Data Protection for VMware version 8.1.11.0 on Windows and Linux Initial Impact: Medium Additional Keywords: TSM, Tivoli, Storage, Manager, TS004744112
Local fix
Change the size of the affected guest disk to a multiple of 2048 sectors (1 MB).

Problem conclusion
Disk size alignment requirement was relaxed to 64KB, which is the minimum allowed by vmware. However the best practice is still to use disk size that is multiple of 1MB (https://kb.vmware.com/s/article/66936).
