Also, as per VMware Interoperability, ESXi 8.0U2 is not supported with vCenter Server 8.0U1. See VMware Product Interoperability Matrix for latest results. Figure 1: Interoperability Result from VMware
PowerProtect Data Manager engineering conducted interoperability tests regarding TSDM in VMware versions 8.0.1 <-> 8.0.2. Here are the results: ESXi 8.0.1 <-> Center 8.0.1 works fine ESXi 8.0.2 <-> Center 8.0.1 fails with the error "The vCenter task for 'SDM Snapshot Sync Full' completed with state 'error'. The vCenter task failed: A specified parameter was not correct: sync Id (500)" ESXi 8.0.2 <-> Center 8.0.2 works fine ESXi 8.0.1 <-> Center 8.0.2 fails with error "vCenter task 'task-72158' failed: VimFault: 'dp.vpx.fault.SnapshotInProgress.summary': DPD Snapshot in progress, TSDM snapshot UUID = '45e3b245-34fb-4d30-adf6-e01f27dc3aaa' (500)"
As vCenter and ESXi upgrades and versions are outside the bounds of PowerProtect Data Manager, it is up to the customer how to proceed. Upgrade so both vCenter and ESXi are on version 8.0.2 Or Downgrade so both vCenter and ESXi are on version 8.0.1 PowerProtect Data Manager does not support version 8.0.2 as of October 2023. For the latest interoperability information, check the E-Lab Navigator support matrix.
