Hi,
We have DPM 2016 running on WS2016 the major PG are VM running on hyper-v cluster 2012 R2, I install DPM, create PG and online protect, all run ok, for prower problems (Puerto Rico hurricane Maria), we need off the datacenter every 2 weekends, but the Monday when the datacenter power on, DPM cannot run any PG and this error is show for the jobs:
The VHD containing the replica or one of it's snapshots could not be mounted or unmounted. (ID 40002)
More information
Recommended action: Ensure that the storage containing the VHD is healthy, mounted, and the VHD is not in use by other processes, and retry the operation.
