Item

Description

Pool Capacity1

Displays information about the pool capacity.

  • Used/Total

Dynamic Provisioning (DP): Displays the pool capacity (used/total) of Dynamic Provisioning and Dynamic Tiering.

Thin Image (TI): Displays the pool capacity (used/total) of Thin Image.

For each value, if the Estimated Configurable capacity is zero, is displayed in the cell.

  • Estimated Configurable2

Dynamic Provisioning (DP): Displays the estimated pool capacity of Dynamic Provisioning and Dynamic Tiering.

Thin Image (TI): Displays the remaining physical pool capacity that is configurable for Thin Image.

V-VOL Capacity1

Displays information about the DP-VOL capacity.

  • Allocated/Total

Dynamic Provisioning (DP): In the Allocated field, total capacity of the Dynamic Provisioning and Dynamic Tiering DP-VOLs to which LU paths are allocated is displayed. In the Total field, total capacity of the Dynamic Provisioning and Dynamic Tiering DP-VOLs is displayed.

For each value, if the Estimated Configurable capacity is zero, is displayed in the cell.

  • Estimated Configurable2

Dynamic Provisioning (DP): Displays the DP-VOL estimated configurable capacity of Dynamic Provisioning and Dynamic Tiering.

Licensed Capacity (Used / Licensed)

Dynamic Provisioning (DP): Displays the licensed capacity of Dynamic Provisioning. Used displays the total capacity of pools for Dynamic Provisioning and Dynamic Tiering,

Thin Image (TI): Displays the licensed capacity of the Thin Image.

Caution: In the Licensed Capacity(Used/Licensed) field, the total capacity of the system is displayed. The total capacity of the system includes capacities of LDEVs assigned to each user and resources other than LDEVs. Therefore, the value displayed as the "Used" Licensed Capacity (Used/ Licensed) might differ from the value of the "Total" Pool Capacity.

Number of Pools

Displays the total number of pools for Dynamic Provisioning, Dynamic Tiering, Thin Image.

Edit Tiering Policies

Displays the Edit Tiering Policies window.

Notes:

  1. The total value of the Total cells under Capacity of each pool type in the Pools tab and the total Used capacity of the Pool Capacity in the Summary table are almost same, but small differences might occur.

If the pool-VOL or DP-VOL for Dynamic Provisioning is created, the estimated configurable pool capacity and estimated configurable V-VOL capacity for Dynamic Provisioning (DP) change. The estimated capacity is calculated based on the configuration of current pools and DP-VOL, and remaining capacity of the shared memory.

  1. The estimated configurable capacity of Dynamic Provisioning is the estimate of the DP-VOL capacity or the pool capacity that can be created by using the remaining capacity of the shared memory after deduction of the capacity of the shared memory used by the current pool and DP-VOL. The value of Estimated Configurable can be used only as a guide, but are not guaranteed to create pools and DP-VOLs having the estimated configurable capacity. If the pool-VOL or DP-VOL for Dynamic Provisioning is created or deleted, the estimated configurable pool capacity and estimated configurable V-VOL capacity for both Dynamic Provisioning change.

Description

Pool Name

Displays the pool name. Clicking the pool name takes you to the pool information window in the lower hierarchy.

Pool ID1

Displays pool ID.

Status

Displays information about the pool status.

Normal: Pool is in a normal status.

Warning: Pool-VOL in the pool is blocked, or the pool is being shrunk.

Exceeded Threshold: Used capacity of the pool exceeds the pool threshold.

Shrinking: Pool-VOL is being reduced.

Blocked: Pool is full, or an error occurred in the pool, indicating that the pool is blocked. If the pool is in both Warning and Blocked status, only Blocked is displayed.

Number of Pool VOLs

Displays the number of pool-VOLs associated with the pool.

Number of V-VOLs

Displays the number of V-VOLs associated with the pool.

For a Thin Image pool, a hyphen (-) is displayed.

Number of Primary VOLs

Displays the number of primary volumes of the Thin Image pairs. If a pool is other than the Thin Image pool, a hyphen (-) is displayed.

RAID level

Displays RAID level. If multiple RAID levels exist in a pool, this field indicates that RAID levels are mixed. If all pool-VOLs are external volumes, a hyphen (-) is displayed.

Capacity

Displays information about the pool capacity.

  • Total: Total capacity of pool.

Using Option, you can select unit of capacity.

One block means 512 bytes and one page means 42 megabytes in a pool capacity of Dynamic Provisioning, Dynamic Tiering, or Thin Image,

  • Used: Used pool capacity.

  • Used (%): Pool usage rates to pool capacity.

Used (%) displays the value which is truncated after the decimal point of the actual value.

User-Defined Threshold (%)

Displays information about the threshold of a pool.

  • Warning: Warning threshold.
