HP XP P9500 Storage - Manual (Page 156)

When the pool-VOL is deleted, the pages contained in the deleted pool-VOL transfer to another
pool-VOL in the same tier. If the used capacity in the tier exceeds Rate of Free Space Newly Allocated
to, the overflowing pages transfer to another tier.
When pool-VOLs in the pool are empty, the appropriate tier is deleted.
Deleting the pool-VOL stops tier relocation. The process resumes after the pool-VOL is deleted.
