Hello,
Please clarify what your issue actually is. Are you trying to remove a previous disk-group that you no longer need? Or are you trying to recover a disk-group in quarantine? Depending on what you are trying to do the solution will differ.
If you are trying to clean a disk and remove all previous data and disk-group information you need to get the disk into a leftover state before removing the metadata. This action will cause permenant data loss and the data/disk-group cannot be recovered.
If you wish to recover a quarantined disk-group then you need to de-quarantine the disk-group and try to bring the disk-group into an online state for recovery. In this case, opening a Support ticket will assist you better. Data recovery should not be done in an online forum but through a log analysis with corrective steps.
Please provide the clarification so we can assist if possible.
Cheers,
Shawn
