View Storage Resource Pools
A Storage Resource Pool is a collection of data pools that are used for capacity and performance management.
About this task
Depending on whether the SRP is a single emulation SRP (FBA or CKD) or a mixed SRP (FBA and CKD), some of the properties that are listed below may appear in a different order or not at all.
Steps
- Select the storage system.
-
Select
Storage > Storage Resource Pools to open the
Storage Resource Pools view.
The following properties display:
- Name—Name of the storage resource pool.
- Emulation—Emulation type (FBA, CKD - not applicable for storage systems that are running HYPERMAX OS 5977, Mixed emulation is also a supported type).
- Overall Efficiency—Overall efficiency
- Physical Used (%)—Physical used capacity, expressed as a percentage
- Physical Capacity (TB)—Physical capacity
- Effective Used Capacity (%)—Effective used capacity, expressed as a percentage
- Provisioned Capacity (TB)—Provisioned capacity
- Unreducible (GB)—Amount of unreducible data at an SRP level (only available on storage systems running PowerMaxOS 5978 Q1 2021 SR or later)
The following controls are available:
- Modify— Modify Storage Resource Pool details
- Add EDisks— Add external disks

to view the following:
Details tab
- Name of the storage resource pool
- Description—Description
- Overall Efficiency—The current data reduction efficiency on this storage resource pool
- Data Reduction—Indicates whether data reduction is enabled or disabled for this storage resource pool.
- Data Reduction Ratio—Data Reduction ratio
- Unreducible (TB)—Amount of unreducible data at an SRP level (only available on storage systems running PowerMaxOS 5978 Q1 2021 SR)
- DRR on Reducible Only —DRR on reducible only (only available on storage systems running PowerMaxOS 5978 Q1 2021 SR)
- Compression State—The compression state
- Default Emulation—The default emulation for the pool (FBA or CKD)
- Effective Used Capacity (%)—The effective used capacity, expressed as a percentage
- Effective Used Capacity (TB)—The effective used capacity
- Physical Capacity (TB)—Physical capacity
- Physical Free Capacity (TB)—Physical free capacity
- Provisioned Capacity (TB)—Provisioned capacity
- Snapshot Modified Capacity (TB)—Snapshot modified capacity
- Snapshot Total Capacity (TB)—Snapshot total capacity
- Reserved Capacity % (0-80)—Reserved capacity
- Usable by RDFA DSE—Specifies whether the Storage Resource Pool can be used for SRDF/A DSE operations. This field does not display for external SRPs.
- Disk Groups—Number of Disk Groups
- Reliability State—This property reflects the overall RAID group and device group health. The possible values for the reliability state are:
- Optimal—All RAID groups in the device group are healthy, and there is sufficient available spare capacity to cover any spindle in the device group.
- NoSpare—All RAID groups in the device group are healthy, and there is insufficient available spare capacity in the device group (one or more spindles cannot be covered).
- Rebuilding—One or more RAID groups in the device group are in a Degraded state, and rebuilding of the degraded RAID groups is taking place (assumes sufficient spare capacity to accommodate rebuilding).
- NoRebuild—One or more RAID groups in the device group are in a Degraded state, and one or more RAID groups in the device group is prevented from rebuilding (due to insufficient spare capacity).
- Failed—One or more RAID groups in the device group are in a Failed state.
- Target Effective Capacity (TB)—Target effective capacity
- Add Capacity State—Add capacity state
- Add Capacity Est. Time to Completion—Add capacity estimated time to completion
- Add Capacity Est. Time to Completion—Add capacity estimated time to completion

The panels also provide links to views displaying objects contained in the pool. There is a number after each link, indicating the number of objects in the corresponding view. For example, clicking the number next to Disk Groups opens a view listing the disk groups in the storage resource pool.
