Hallo VMware Community,
we are running VSA Backup of CommVault SIMPANA. We are using a VSA Proxy. To the Proxy the VMFS-5 LUNs are mapped read-only so that we can use SAN as transport mode for the VMs which are located on that datastores.
We have testet many things but always still getting the error message "Failure Reason:Could not read data from the virtual disk" and the Job failed. At the beginning we started with one Subclient for all the VMs but now we switched to one Subclient per VM so that the jobs are running sequentially step by step but the error still occurs.
Error Code (at SIMPANA Console):
Description: Unable to read the disk [] for virtual machine [xxx] on Host [xxx]. [Beim Verarbeiten der Anfrage ist mindestens ein Fehler aufgetreten., Failed to ReadCurrVmdkFile (W32.774)]

We are running the latest version of VMware ESXi and also the latest version of the vSphere Server.
Maybe someone of you is also using VSA backup of SIMPANA and can help us to resolve this issue.
Thanks a lot
Best Regards
