Modifying Capacity of a Storage Pool (for 2600 V3 Video Surveillance Edition)

Modifying Capacity of a Storage Pool (for 2600 V3 Video Surveillance Edition)

When the storage pool capacity is insufficient, you can expand it to meet actual needs. When the storage pool is with surplus capacity, you can reduce it to release storage space.

Prerequisites

  • The Health Status of the storage pool is Normal.
  • The disk domain has available storage space for capacity expansion of the storage pool
  • The reduced capacity must be smaller than maximum capacity for reduction.

Procedure

  1. Choose Provisioning > Storage Pool.
  2. Select the storage pool you want to expand and click Modify Capacity.

    The Modify Capacity dialog box is displayed.

  3. In Operation, select the mode of modifying capacity. The modes are Expand capacity and Reduce capacity.

    • Expand the capacity of a storage pool.
      1. Select the storage tier you want to expand or create.
      2. You can create a new storage tier or expand the existing storage tier to expand storage pools.
        • To create a storage tier, configure the RAID policy and in Capacity, enter the capacity of the storage tier.
          Table 5-43 Storage tier parameters

          Parameter

          Description

          Value

          RAID Policy

          RAID level. The system supports RAID 0, RAID 1, RAID 10, RAID 3, RAID 5, RAID 50, and RAID 6.

          NOTE:

          RAID 0 can only be configured using the CLI. For details, see the command reference specific to your product model and version.

          [Example]

          Use NL-SAS or SATA disks to create RAID 6 (26D+2P)

          Capacity

          Capacity that the storage tier provides for the storage pool.

          Two capacity levels are provided: TB and GB.

          The capacity must be no larger than the available capacity of the storage tier.

        • To expand a storage tier, in Added Capacity, enter the added capacity of the storage tier.
        NOTE:
        • You can configure RAID policy only for new created storage tier. For the storage tier already exists in the storage pool, you cannot modify its RAID policy.
        • The number of RAID data disks of different storage pool tiers must be a multiple of 1, 2, 4, or 8.
    • Reduce the capacity of a storage pool.
      1. Select the storage tier you want to reduce.
      2. In Reduction Capacity, enter the capacity of the storage tier to be reduced.

  4. Confirm the capacity modification of the storage pool.

    1. Click OK.
      NOTE:

      If a security alert dialog box is displayed, confirm the information in the dialog box and select I have read and understand the consequences associated with performing this operation. Click OK.

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