Let's assume a situation when:
1) Customer created a LUN and configured it as a Mount Path extending current Disk Library with brand new MP
2) Customer ran only a few backup that went through this Mount Path
3) Customer accidentaly deleted this LUN from OS side
4) There are no secondary copies
What's it's the best way to clear out this situation? Of course assuming that some backups needs to be deleted and due to deduplication nature some jobs that went to affected Mount Path can have shared blocks with other Mount Paths within same Disk Library.
By default such unpresent Mount Path/LUN will be automatically marked as disabled/offlined in CommCell Console. Manually deleting jobs that went to this MP is possible, but deleting such MP is not allowed as it's used for dedup store previously even if such MP is completely lost and there is no way to take it back to life.
So... how to clean environment after such disaster without sealing the store? Of course we assume that it will be disruptive and some backups will be definetely lost (not only these logically resided on affected LUN). I cannot find any related documentation/KB.
