Forgetting a storage array
About this task
Forget a storage array if it has been deleted from use by metro node and it is no longer used for I/O. You can forget a LUN
from the Show Logical Units screen, or from the Rediscover Storage Array dialog box while rediscovering a storage array.
Steps
1. From the GUI main menu, do one of the following:
a. In a metro node Local:
i. Select Provision Storage.
ii. In the View by drop-down, select Storage Arrays.
b. In a metro node Metro:
i. Select Provision Storage.
ii. In the Provision on drop-down, select the cluster of the storage array.
iii. In the View by drop-down, select Storage Arrays.
2. In the Storage Arrays view, select a storage array, and then select MORE>Show Logical Units.
3. In the Show Logical Units screen, click Forget Unreachable LUNs.
A confirmation dialog box is displayed.
4. Click Yes.
5. View the results of the operation, and then click Close.
Storage array connectivity status
The following table describes the array connectivity states.
Connectivity state
Definition
OK The array is functioning normally; both directors can see each LUN exported from the array.
Unknown Metro node is unable to report on the connectivity status of the array.
Error One or more directors cannot see a LUN exported from the array.
Degraded A LUN exported from the array does not have two paths to each director.
Storage volumes
About storage volumes
A storage volume is a LUN exported from an array. When metro node discovers an array, the Storage Volumes view shows all
LUNs exported from the array. You must claim, and optionally name these storage volumes before you can use them in a metro
node cluster. Once claimed, you can divide a storage volume into multiple extents (up to 128), or create a single extent that uses
the entire capacity of the storage volume.
To claim storage volumes, use the Claim Storage wizard, which assigns a meaningful name to the storage volume. Meaningful
names help to associate a storage volume with a specific storage array and LUN on that array, and helps during troubleshooting
and performance analysis.
For thinly-provisioned storage volumes, you can request a thin rebuild for local or distributed mirrors. Setting a storage volume
rebuild type provides more information.
