CommentCLI EquivalenceStorageSetting Property
Time when the volume expires. (In CLI,
the value is the delta, whereas here it
is the actual date and time.)

Calculating Capacity for StoragePool and StorageVolume
Calculate capacity for StoragePool and StorageVolume through one of the following methods.
Primordial Storage Pool
The primordial pool represents the raw capacity of the array. Its TotalManagedSpace therefore
represents the capacity of all the disk drives in the array, whether admitted or not, minus capacity
lost due to chunklet formatting. The RemainingManagedSpace option represents the capacity
of the disks that are in a New state, namely those that have not been admitted.
StoragePool.SpaceLimit has the same value as TotalManagedSpace.
Concrete Storage Pool
TPD_AllocatedFromStoragePool.SpaceConsumed between a primordial and a concrete
pool (3PAR:all-FC, 3PAR:all-NL or 3PAR:all-SSD) represents the raw capacity taken by the concrete
pool. The capacity used for metadata in the creation of the concrete pool can be calculated by
(TPD_AllocatedFromStoragePool.SpaceConsumed –
ConcreteStoragePool.TotalManagedSpace).
TotalManagedSpace for a concrete storage pool represents the raw capacity that can be used
to create storage volumes, dynamic storage pool, or delta replica storage pool.
RemainingManagedSpace for a concrete storage pool represents how much raw capacity is
available for creating a new volume, dynamic storage pool, or delta replica storage pool. After
a volume, dynamic storage pool or delta replica storage pool is created, the raw size of the new
volume or the actual raw size allocated to the dynamic storage pool or delta replica storage pool
is subtracted from the RemainingManagedSpace of the parent concrete pool. This volume raw
size is also represented in TPD_AllocatedFromStoragePool.SpaceConsumed between the
parent concrete pool and the storage volume, dynamic storage pool, or delta replica storage pool.
TotalManagedSpace for a concrete storage pool is equal to RemainingManagedSpace for
the concrete storage pool value plus TPD_AllocatedFromStoragePool.SpaceConsumed
option from all the storage volumes, dynamic storage pool, or delta replica storage pool allocated
from the pool.
StoragePool.SpaceLimit has the same value as TotalManagedSpace.
Dynamic Storage Pool (CPG)
TPD_AllocatedFromStoragePool.SpaceConsumed between a concrete pool and a dynamic
storage pool (DSP) represents the raw capacity taken by the DSP. Capacity used for metadata in
the creation of the pool can be calculated by
(TPD_AllocatedFromStoragePool.SpaceConsumed –
DynamicStoragePool.TotalManagedSpace).
TotalManagedSpace for a DSP represents the logical capacity that can be used to create storage
volumes or delta replica storage pool. RemainingManagedSpace for a DSP represents what
logical capacity is available for creating a new volume or delta replica storage pool. After a
volume or delta replica storage pool is created, the logical size of the new volume or the actual
logical size allocated to delta replica storage pool is subtracted from the
