During disaster recovery (DR) tests, QAS is unable to connect to the domain controllers that have been set up in the DR environment. QAS is still attempting to connect to the DCs that were being used before the DR test and is unable to reach any of them.
While in this state the vas_snapshot script hangs so a snapshot can not be captured of the system.
There are some known issues with QAS's handling of offline DCs which can cause problems in DR environments.
