HP 3PAR Recovery Manager Software for Microsoft SQL Server Licenses - Manual (Page 63)

NOTE: When mounting in read-write mode, the system uses VDS API to make the volume read
and write enabled. However, if there is another operation on the disk and the device is locked,
you cannot unmount the volume. If you attempt to unmount a locked volume, the system displays
the following error message:
ERROR: COM call “pVolumeMF->Dismount(TRUE,FALSE)” failed.
Returned HRESULT = 0x80042413
Error text:
Error: There was an expected HRESULT error catched: 0x80042413
error code>
This error message indicates the same issue as VDS_E_DEVICE_IN_USE.
To resolve the issue, restart the VDS service or reboot the machine.
NOTE: HP 3PAR Recovery Manager for SQL only supports snapshot exposure to a host.
Recovery Manager does not support mounting a virtual copy to a drive letter or to a path involving
a cluster shared drive letter.
