The PD_VVC record stores performance data indicating the operation status of the V-VOL for Dynamic Provisioning. This is a multi-instance record.

Note:

Information about Copy-on-Write Snapshot V-VOLs, Thin Image V-VOLs, and the V-VOLs that are not associated with the Dynamic Provisioning pool is not collected.
If the Dynamic Provisioning pool to which the Dynamic Provisioning V-VOL belongs is blocked, RAID Agent does not collect information about the V-VOL. However, if the Dynamic Provisioning pool is blocked because the usage rate of the pool capacity is 100%, RAID Agent collects information about the V-VOL.

Collection Interval

3600

Key Field

LDEV_NUMBER

Lifetime

From when the V-VOL of Dynamic Provisioning is set up to when it is removed.

Fields

Field Name	Description	Access Type	Format
ATTRIBUTE	An attribute that indicates whether Full Allocation is enabled or disabled and whether the Data Direct Mapping is enabled or disabled: If Full Allocation is enabled Full Allocation If Data Direct Mapping is enabled Data Direct Mapping If Full Allocation and Data Direct Mapping are disabled, or Full Allocation and Data Direct Mapping are not supported by the storage system (Null string)	1, 2	string(20)
COLLECTION_TIME	Time (in GMT) when the data was collected from the storage system.	1, 2	time_t
DATA_SAVING	Settings of the capacity saving function (deduplication and compression) for a volume: 0x00 Disabled 0x02 The capacity saving function (compression) is enabled. 0x03 The capacity saving function (compression and deduplication) are enabled.	1, 2, 3, 4	unsigned char
DEDUP_MODE	The capacity saving processing mode: Inline Inline mode. Post-process Post-process mode. "" This function is not supported.	1, 2, 3, 4	string(32)
FREE_CAPACITY	Free capacity of the V-VOL (MB).¹ The value is calculated based on the following formula: VIRTUAL_VOLUME_CAPACITY - USED_CAPACITY	1, 2, 3, 4	double
INPUT_RECORD_TYPE	Record type identifier, which is always set to VVC.	1, 2, 3, 4	string(8)
INTERVAL	Interval (in seconds) at which information is collected.	1, 2, 3, 4	ulong
LDEV_NUMBER	Logical device number of the V-VOL.	1, 2, 3, 4	string(16)
POOL_FREE_CAPACITY_RATE	Percentage of free capacity in the V-VOL for a Dynamic Provisioning pool.¹ The value is calculated based on the following formula: (PD_PLC_FREE_CAPACITY / PD_VVC_FREE_CAPACITY) * 100 If the free capacity in the V-VOL is small, the value might become extremely large. *Example:* If the free capacity in the pool to which the V-VOL belongs is 100 GB and the free capacity in the V-VOL is 10 GB, the value is 1000%.	1, 2, 3, 4	double
POOL_ID	ID of the Dynamic Provisioning pool to which the V-VOL belongs.	1, 2, 3, 4	string(8)
RECORD_TIME	Time (in GMT) when the record was stored.	1, 2, 3, 4	time_t
RESERVED_CAPACITY	The capacity for the reserved pages of the virtual volume (MB).	1, 2	double
THRESHOLD	Threshold value (%) set for the free capacity in the Dynamic Provisioning pool to which the V-VOL belongs, as a percentage of the free capacity in the V-VOL (the value of the POOL_FREE_CAPACITY_RATE field). This value is specified in Storage Navigator.	1, 2	float
USAGE_RATE	Of the virtual capacity of the V-VOL, the percentage of the capacity actually used (the usage rate of the pool capacity).¹ The value is calculated based on the following formula: (USED_CAPACITY / VIRTUAL_VOLUME_CAPACITY) * 100 If pool areas are reserved, the percentage includes the capacity for the reserved pages.	1, 2, 3, 4	float
USED_CAPACITY	The actual amount of V-VOL capacity being used (MB).¹ If pool areas are reserved, the value includes the capacity for the reserved pages.	1, 2, 3, 4	double
VIRTUAL_VOLUME_CAPACITY²	The virtual capacity of the V-VOL (MB).¹	1, 2, 3, 4	double
Notes: This value differs from the device capacity information that is recognized by the host because this information is managed by the storage system. This value differs from the setting value of Storage Navigator because this value is the actual assigned value.
