All data has been deleted from a virtual pool. The CLI delete pool <name> command fails even though show pool capacity displays 0 used 0 C-Clips and 0 files for the virtual pool.
Although all the customer data has been deleted from the virtual pool, reflections are still left that are created to leave an audit trail of all deletes. Due to reflections being present the pool is unable to be deleted.
By default reflections never expire. A Request for Price Quotation (RPQ) can be submitted to request the setting of an expiry time on the cluster for reflections. After setting the expiry time, reflections older than the expiry time will be deleted. The expiry time affects all reflections on the cluster and is not specific to a pool.
