Capacity status of storage controllers

Normal

The usage rate of the capacity managed by the storage controller is not high and is normal.

Specifically, the usage rate is as follows:

• The usage rate for the maximum logical capacity that can be managed on the storage controller is less than the maximum (storage pool depletion threshold is less than 80%).

• The usage rate for the logical capacity managed on the storage controller is less than 80%.

Warning

The usage rate for the capacity managed by the storage controller is high. Or, maximum capacity expansion of the storage controller, which operates when capacity usage is high, is not being performed.

Specifically, the usage rate is as follows:

• The usage rate for the maximum logical capacity that can be managed on the storage controller has exceeded the maximum (storage pool depletion threshold is 80%), but is below the storage controller depletion threshold.

• The usage rate for the logical capacity managed on the storage controller is 80% or more and is less than the storage controller depletion threshold, and the storage controller's capacity has not been expanded to the maximum (using the capacity for the Rebuild) at least for five minutes.

Error

The usage rate for the capacity managed by the storage controller is high, and the capacity might be depleted.

Specifically, the usage rate is as follows:

• The usage rate for the maximum logical capacity that can be managed on the storage controller has exceeded the storage controller depletion threshold.

• The usage rate for the logical capacity that is managed on the storage controller has exceeded the storage controller depletion threshold.
