Modifying the Advanced Properties of a Storage Pool

Modifying the Advanced Properties of a Storage Pool

This operation enables you to modify the advanced properties of a storage pool.

Procedure

  1. Log in to DeviceManager.
  2. Choose Provisioning > Storage Pool.
  3. Select the storage pool whose properties you want to modify and click Properties.

    The Properties of Storage Pool dialog box is displayed.

  4. Set advanced properties for the storage pool.
    1. In the Properties of Storage Pool dialog box, click the Advanced tab.

      Table 5-1 describes the related parameters.

      Parameter

      Description

      Setting

      Used Capacity Alarm Threshold (%)

      If the storage pool contains a LUN with value-added service, or a file system with value-added service, or a thin LUN, or a thin file system, when the percentage of the used capacity of the storage pool to the total capacity of the storage pool (the used capacity for short as below) reaches the used capacity alarm threshold, the system generates an alarm. The alarm is generated in 3 circumstances:
      • When the used capacity reaches the used capacity alarm threshold, the system generates an alarm informing that the capacity of storage pool is insufficient.
      • When the used capacity alarm threshold is no greater than 88 and the used capacity reaches 90%, the system generates an alarm informing that the storage pool is running out.
      • When the used capacity alarm threshold is greater than 88 and the used capacity reaches (used capacity alarm threshold +2)%, the system generates an alarm informing that the storage pool is running out.
      NOTE:
      If the used capacity alarm threshold is set as 85, when the used capacity reaches 85%, the system generates an alarm informing that the capacity of storage pool is insufficient, and when the used capacity reaches 90%, the system generates an alarm informing that the storage pool is running out. If the used capacity alarm threshold is set as 91, when the used capacity reaches 93%, the system generates an alarm informing that the storage pool is running out.

      A proper used capacity alarm threshold helps you monitor the capacity usage of a storage pool.

      [Value range]

      1 to 95

      [Default Value]

      80

      Data Protection Capacity Alarm Threshold (%)

      When ratio the data protection capacity of the storage pool to the total capacity of the storage pool exceeds the capacity alarm threshold, the system generates an alarm.

      [Value range]

      1 to 100

      [Default Value]

      100

    2. Click OK.

      The Execution Result dialog box is displayed indicating that the operation succeeded.

    3. Click Close.
