Table B-15  Common operations to manage storage pools

Operation

Scenario

Description

Create

Application servers only use storage space from storage pools of a storage system. Therefore, you need to create storage pools to ensure sufficient storage space for application servers.

A storage pool with only one storage tier does not support SmartTier.

Query

Query status and capacity information about storage pools and storage tier information.

-

Modify

Modify capacity alarm thresholds.

Modify the data migration mode and capacity alarm parameters of storage pools to meet current services' requirements.

  • To configure SmartTier, a storage pool must contain at least two storage tiers.
  • Before enabling the SSD cache mode, ensure that the following conditions are met:
    • A storage pool contains the high-performance tier.
    • The data migration plan is set to Periodical.
    • The SSD cache mode has not been enabled.

Modify capacities.

If the capacity of a storage pool is insufficient, expand its capacity. If the overcapacity of a storage pool occurs, reduce its capacity to release storage space.

Available space of the disk domain where the storage pool resides can meet requirements for expanding the storage pool.

Delete

If a storage pool is no longer used, delete it.

Before deleting a storage pool, ensure that LUNs in the storage pool have been deleted.

NOTE:
