    Table 1 Storage pool parameters

    Parameter

    Description

    Name

    Name of a storage pool.

    Storage Pool ID

    ID of a storage pool.

    Status

    Status of a storage pool. Possible values are Normal, Faulty, Write-protected, Stopped, Faulty and write-protected, Migrating data, Degraded, Rebuilding data, Migrating services, and Unknown.

    NOTE:

    When expanding or reducing the capacity of a storage pool on DeviceManager, the task is at the Notify EDS scale out or Clear EDS on the storage node step, and the storage pool is in normal status, Status of the storage pool will be displayed as Migrating services. On the CLI, Migrating services is not a possible value of storage pool status. A storage pool in such status will be displayed as Normal.

    Service Type

    Service type of a storage pool.

    Key Service

    • Internal key service: The built-in key management function of the system is used.
    • External key service: An external key management server is used for management.

    Total Usable Capacity

    Actual usable physical disk space of a storage pool (Total physical disk capacity – Capacity consumed by EC redundancy – Capacity lost due to hardware faults).

    Used Capacity

    Used physical disk space of a storage pool.

    NOTE:

    The Used Capacity of a storage pool consists of user data, snapshot protection space, non-deleted volume space in the recycle bin, E2E DIF verification data, remote replication/HyperMetro differential logs, and private snapshot space for asynchronous remote replication. Therefore, the value of Used Capacity of a storage pool may be greater than the sum of Used Capacity of all volumes in the storage pool.

    Capacity Usage

    Ratio of Used Capacity to Total Usable Capacity of a storage pool.

    Total Available Capacity

    Total amount of data that can be written into a storage pool.

    Used Available Capacity

    Total amount of data that has been written into a storage pool.

    Security Level

    Security level of a storage pool.
