The PD_PLTC record stores performance data indicating the operation status for each tier type of a Dynamic Provisioning pool that has tier management enabled. This is a multi-instance record.

Note:

RAID Agent does not collect information about a Copy-on-Write Snapshot pool or a Thin Image pool, or a Dynamic Provisioning pool that has tier management disabled.
If the Dynamic Provisioning pool is blocked, RAID Agent does not collect information about the pool. However, if the Dynamic Provisioning pool is blocked because the usage rate of the pool capacity is 100%, RAID Agent collects information about the pool.
The capacity information for this record is not exactly the same as the device capacity information that is recognized by the host because this capacity information is managed by the storage system.

Collection Interval

3600

Key Fields

POOL_ID and TIER_TYPE

Lifetime

From when the tier and a Dynamic Provisioning pool that has tier management enabled are set up to when it is removed.

Fields

Field Name	Description	Access Type	Format
COLLECTION_TIME	Time (in GMT) that the data was collected from the storage system.	1, 2	time_t
DISPLAY_DRIVE_TYPE	Type of tier (display name).	1, 2	string(32)
FMC_CAPACITY_EXPANSION_RATE	Expansion percentage of the FMC capacity by using accelerated compression.^{1, 2}	1, 2	float
FMC_POOL_CAPACITY_FREE	Total amount of free capacity in the FMC volumes that make up the tier (GB).^{2, 3}	1, 2	double
FMC_POOL_CAPACITY_SAVING	Amount of used capacity in the tier that was reduced by the FMC compression functionality (GB).⁴	1, 2	double
FMC_POOL_CAPACITY_SAVING_RATE	Percentage of used capacity in the tier that was reduced by the FMC compression functionality. The value is calculated based on the following formula: (FMC_POOL_CAPACITY_SAVING / FMC_POOL_CAPACITY_USED) * 100	1, 2	float
FMC_POOL_CAPACITY_TOTAL	Total amount of capacity of the FMC volumes that make up the tier (GB).^{2, 3}	1, 2	double
FMC_POOL_CAPACITY_USAGE_RATE	Usage percentage of the capacity of the FMC volumes that make up the tier.² The value is calculated based on the following formula: (FMC_POOL_CAPACITY_USED / FMC_POOL_CAPACITY_TOTAL) * 100	1, 2	float
FMC_POOL_CAPACITY_USED	Total amount of capacity of the FMC volumes that make up the tier that is being used by data.^{2, 5}	1, 2	double
FREE_CAPACITY	Free capacity of the tier (GB).³ The value is calculated based on the following formula: PD_PLTC_TOTAL_CAPACITY - PD_PLTC_USED_CAPACITY	1, 2	double
INPUT_RECORD_TYPE	Record type identifier, which is always set to PLTC.	1, 2	string(8)
INTERVAL	Interval (in seconds) at which information is collected.	1, 2	ulong
MONITORING_MODE	Monitoring mode: Period Mode Continuous Mode	1, 2	string(32)
PHYSICAL_FMC_CAP_USAGE_RATE	Usage percentage of the physical capacity of the parity groups that make up the tier. The value is calculated based on the following formula: (PHYSICAL_FMC_CAPACITY_USED / PHYSICAL_FMC_CAPACITY_TOTAL) * 100	1, 2	float
PHYSICAL_FMC_CAPACITY_FREE	Total amount of free capacity in the physical capacity of the parity groups that make up the tier (GB).⁶	1, 2	double
PHYSICAL_FMC_CAPACITY_TOTAL	Total amount of the physical capacity of the parity groups that make up the tier (GB).	1, 2	double
PHYSICAL_FMC_CAPACITY_USED	Total amount of used capacity in the physical capacity of the parity groups that make up the tier (GB).⁶	1, 2	double
POOL_ID	ID of the pool.	1, 2	string(8)
RECORD_TIME	Time (in GMT) that the record was stored.	1, 2	time_t
TIER_NUMBER	Tier number.	1, 2	string(8)
TIER_TYPE	Tier type.⁷	1, 2	string(32)
TOTAL_CAPACITY	Capacity of the tier (GB).³	1, 2	double
USAGE_RATE_IN_POOL	Of the total capacity of a Dynamic Provisioning pool that has tier management enabled, the percentage of the pool used by the tier (%). The value is calculated based on the following formula: (PD_PLTC_USED_CAPACITY / PD_PLC_TOTAL_ACTUAL_CAPACITY) * 100	1, 2	float
USAGE_RATE_IN_TIER	Of the capacity of the tier, the percentage of the capacity used (%). The value is calculated based on the following formula: (PD_PLTC_USED_CAPACITY / PD_PLTC_TOTAL_CAPACITY) * 100	1, 2	float
USED_CAPACITY	Amount of tier capacity that is actually being used (GB).⁵	1, 2	double
Notes: If the number of pool volumes created from parity groups that support the accelerated compression function is less than the physical capacity of those parity groups, the value is always 100. If no parity group supports the accelerated compression function, the value is 0. If the pool contains a parity group for which accelerated compression is also enabled, the value is the amount that includes the capacity of the expanded area. A value is stored only when the pool contains a parity group for which accelerated compression is also enabled. In other cases, the value is 0. If the pool contains a parity group for which accelerated compression is also enabled, the value is the amount before compression. If the pool contains a parity group for which accelerated compression is also enabled, the value is the amount after compression. FMC is the value to be stored when the drive type is FMC, FMD DC2, or FMD HDE. SSD Mixed is the value to be stored when different types of flash drives exist.
