Removing disk groups from virtual pools

You can remove one or more disk groups, but not all, from a virtual pool without losing data as long as there is enough space available in the remaining disk groups to move the data into.

When a virtual disk group that contains active volume data is removed, that volume data will drain (be moved) to other disk group members within the pool (if they exist). If the pool has enough space to contain the data, the disk group is removed. If the pool does not have enough space to contain the data, the disk group is not removed. When the last disk group is removed, the pool ceases to exist and will be deleted from the system automatically. Alternatively, the entire pool can be deleted, which automatically deletes all volumes and disk groups residing on that pool.
