Pools
The storage system supports up to 128 pools, each of which can contain up to 1024 pool-VOLs and 63,232 DP-VOLs per pool. A pool for Dynamic Provisioning for Mainframe cannot be used in conjunction with other pools.
A pool number must be assigned to a pool. Multiple DP-VOLs can be related to one pool. Multiple pool-vols can be registerred in one pool. Pools cannot be shared between Dynamic Provisioning and Dynamic Provisioning for Mainframe.
If you want to delete a pool, you must first delete all DP-VOLs related to the pool. When the pool is deleted, all data in the pool is also deleted.
Pool-VOLs
Pool-VOLs are grouped together to create a pool. When you create a new pool, you can select one or more pool-VOLs from the available pool-VOLs. Every pool must have a pool-VOL with System Area.
Dynamic Provisioning for Mainframe does not automatically balance the usage levels among pool-VOLs if the cache memory is not redundant or if the pool usage reaches up to the threshold.
Pool-VOLs can be added to and deleted from pools. Removing a pool-VOL does not delete the pool or any related DP-VOLs.
