Understanding storage pool states

The Ignite management console tracks two types of storage pool states. Power states are displayed at the top of each Storage Pool Overview page. Logical states are determined based on the storage pool's logical relationships to other objects in your Cloudistics infrastructure.

Power States

Cloudistics considers storage pools to be in one of three power states at all times:

  • Powered on: The storage pool is reachable and able to run application instances.
  • Powered off: The storage pool has been powered off by the user (for example, for maintenance).
  • Unreachable: The storage pool does not respond to Ignite and was not powered off by the user. If a storage pool in your cloud infrastructure is unreachable, check your network connectivity or contact customer support.

Logical States

Unlike power states, logical states may overlap. Logical states include:

  • Unregistered: The storage pool has not been registered. Unregistered storage pools cannot be used by applications. Cloudistics strongly recommends registering all storage pools.
  • Registered and Not Connected: The storage pool has been registered, but has not been connected to a migration zone. Unconnected storage pools cannot be used by applications.
  • Registered and Connected to a Migration Zone: The storage pool has been registered and is connected to at least one migration zone. This is the only logical state in which a storage pool can be used by applications.
