Unable to expose previously created persistent snapshot

When working with VSS following problem arises. We create a persistent snapshot of disk volume (e.g. vshadow -p -script=snapshot.cmd f:). Creation is successful and snapshot is visible (vshadow -q). Then we restart the computer. After rebooting the snapshot is still visible, but it is not possible to perform the operation expose (e.g. vshadow.exe –el=%SHADOW_ID_1%, "c:\test1" returns an error). Snapshot removal performed without errors.

(Option: Expose a shadow copy)
- Setting the VSS context to: 0xffffffff
- Exposing shadow copy {865abd59-ddbd-46b0-aae8-cfd350b85862} under the path 'c: \ test1'
- Checking if 'c: \ test1 \' is a valid empty directory ...

Without rebooting snapshot creation and exposing work without errors. Testing was done on Windows 2012 on a few VSS hardware providers.

After reboot iscsi target does not automatically connect, so vss unable to find device during expose.
