Logical Device Properties

Selecting a logical device and clicking Properties dispaysthe following tabs: Logical Drive and Cache Settings.

Logical Drive

The Logical Drive tab includes the following information:

§         Status—Possible values are Quick Init, Impacted,  Degraded, Failed, Offline, and Optimal (the 'everything is good' state).

§         Array nameThis is a modifiable field that displays the name assigned to this array at creation. You can click in the array name field and rename the array using any unique combination of up to 15 standard ASCII characters.

§         TypeThe RAID level or volume type of the selected array.

§         CapacityThe physical capacity of the selected array in gigabytes with the number of blocks in parenthesis.

§         Stripe SizeWhere applicable, the stripe size of the selected array.

§         Hot spareIndicates, for redundant arrays, if a hot spare protects the selected array.

§         Logical drive numberA number assigned to the selected array by the controller. This number is only used by the controller.

Note: If the system is booting from the controller that this array is connected to, the lowest number array (typically array 0) is the boot device. ACU provides an option to select any array and make it the boot device. If you choose to do so, the array you choose to make the boot device becomes array 0. This action may result in the renumbering of other arrays.

Cache Settings

The Cache Settings tab duplicates the options presented in the advanced version of the Create Array wizard. You can choose to modify the settings for both read and write cache.

Write cache can be set to disable, enable always, or (if the controller is fitted with a battery) enable when protected.

Read cache can be enabled or disabled.
