When Dismantling HDP pools, ensure you either go through or note the following steps:
1. Ensure Virtual VOL's aren't being accessed (check paths)
2. Remove Pool VOL'S from Pool(s). NB: The final Pool Vol will have to removed when destroying the pool itself as this holds the Meta data for the pool.
3. After deleting the pool you will notice that 1 x Pool VOL will be 'blocked. or possibly more if you haven't removed them from the pool before deleting the pool itself.
4. To render these Pool VOL's useful again you can either "Restore LDEVS" (this can fail sometimes and if so you will be required to re-format the Pool VOL's. NB: LDEV Addressing will stay in tact)
5. Following this you can either remove the pool VOL's or reassign to another pool provided the RAID type is OK e.g. 'new pool' is built using the same raid configuration
