Table 39 Properties Relevant to TPVV Properties Uint64 NumberOfBlocks Description The logical size of the TPVV, in blocks. Uint64 NumberOfRawBlocks Uint64 ConsumableBlocks Total number of logically contiguous blocks including overhead and metadata, of size Block Size, which form this Extent. The total size of the Extent can be calculated by multiplying BlockSize by NumberOfRawBlocks. If the BlockSize is 1, this property is the total size of the Extent. The logical size of the TPVV, in blocks, same as NumberOfBlocks. Uint64 ProvisionedConsumableBlocks Uint32 SnapAllocationLimit (percentage) The number blocks that are currently allocated and visible to host. For example, a RAID-10 volume with ConsumableBlocks = 100 GB, but only 10 GB is actually used, then ProvisionedConsumableBlocks is 10 GB. Applicable only to a thin-provisioned volume. The SD space of the volume is prevented from growing beyond the specified percentage of the volume size. Uint32 SnapAllocationWarning (percentage) Generate a warning alert when SD space of the volume exceeds the specified percentage of the volume size. Uint32 UserAllocationLimit (percentage) The user space of the volume is prevented from growing beyond the specified percentage of the volume size. Applicable only to a thin-provisioned volume. Uint32 UserAllocationWarning (percentage) Generate a warning alert when user space of the volume exceeds the specified percentage of the volume size. Applicable only to a thin-provisioned volume.

NumberOfBlocks

Total number of logically contiguous blocks including

overhead and metadata, of size Block Size, which form

Uint64

NumberOfRawBlocks

this Extent. The total size of the Extent can be calculated

by multiplying

BlockSize

. If

the

BlockSize

is 1, this property is the total size of the

Extent.

The logical size of the TPVV, in blocks, same as

NumberOfBlocks

Uint64

ConsumableBlocks

The number blocks that are currently allocated and visible

to host. For example, a RAID-10 volume with

Uint64

ProvisionedConsumableBlocks

ConsumableBlocks

= 100 GB, but only 10 GB is

actually used, then

ProvisionedConsumableBlocks

is 10 GB. Applicable only to a thin-provisioned volume.

The SD space of the volume is prevented from growing

beyond the specified percentage of the volume size.

Uint32

SnapAllocationLimit

(percentage)

Generate a warning alert when SD space of the volume

exceeds the specified percentage of the volume size.

Uint32

SnapAllocationWarning

(percentage)

The user space of the volume is prevented from growing

beyond the specified percentage of the volume size.

Applicable only to a thin-provisioned volume.

Uint32

UserAllocationLimit

(percentage)

Generate a warning alert when user space of the volume

exceeds the specified percentage of the volume size.

Applicable only to a thin-provisioned volume.

Uint32

UserAllocationWarning

(percentage)

If TRUE, the volume is thinly provisioned.
