Manage array LUNs with System Manager - ONTAP 9.7 and earlier
Suggest changes
PDFs
You can use ONTAP System Manager classic (available in ONTAP 9.7 and earlier) to assign array LUNs to an existing aggregate and manage array LUNs.
Assign array LUNs
You can use System Manager to assign unassigned array LUNs to an existing aggregate to increase the size of the aggregate.
-
You can assign array LUNs if the following conditions are true:
-
The container type of the selected array LUNs must be “unassigned”.
-
The disks must be connected to nodes in an HA pair.
-
The disks must be visible to the node.
-
-
For MetroCluster configurations, you cannot use System Manager to assign array LUNs as spares.
You must use the command-line interface instead.
-
Click Storage > Aggregates & Disks > Array LUNs.
-
Select the array LUNs, and then click Assign.
-
In the Assign Array LUNs dialog box, select the node to which you want to assign the array LUNs.
-
Click Assign.
Reassign spare array LUNs to nodes
You can use System Manager to reassign the ownership of spare array LUNs from one node to another to increase the capacity of an aggregate.
-
You can reassign array LUNs if the following conditions are true:
-
The container type of the selected array LUNs must be “spare”.
-
The disks must be connected to nodes in an HA pair.
-
The disks must be visible to the node.
-
-
For MetroCluster configurations, you cannot use System Manager to reassign array LUNs as spares.
You must use the command-line interface instead.
-
Click Storage > Aggregates & Disks > Array LUNs.
-
Select the spare array LUNs that you want to reassign, and then click Assign.
-
In the Warning dialog box, click Continue.
-
In the Assign Array LUNs dialog box, select the node to which you want to reassign the spare array LUNs.
-
Click Assign.
Zeroing spare array LUNs
You can use System Manager to erase all the data and to format the spare array LUNs by writing zeros to the array LUNs. These array LUNs can then be used in new aggregates.
When you zero the spare array LUNs, all the spares in the cluster, including disks, are zeroed. You can zero the spare array LUNs for a specific node or for the entire cluster.
-
Click Storage > Aggregates & Disks > Array LUNs.
-
Click Zero Spares.
-
In the Zero Spares dialog box, select a node or “All nodes” from which you want to zero the array LUNs.
-
Select the Zero all non-zeroed spares check box to confirm the zeroing operation.
-
Click Zero Spares.
About disks and array LUNs
A disk is the basic unit of storage for storage systems that use ONTAP software to access native disk shelves. An array LUN is the basic unit of storage that third-party storage arrays provide to storage systems that run ONTAP software.
ONTAP software enables you to assign ownership to your disks and array LUNs, and to add them to an aggregate. ONTAP software also provides a number of ways to manage your disks, including removing them, replacing them, and sanitizing them. Because array LUNs are provided by the third-party storage array, you use the third-party storage array for all other management tasks for array LUNs.
You can create an aggregate using either disks or array LUNs. After you have created the aggregate, you manage it using ONTAP software in exactly the same way, whether it was created from disks or array LUNs.
Array LUNs window
The Array LUNs window enables you to assign ownership to your array LUNs and to add them to an aggregate.
The Array LUNs link in the left navigation pane is displayed only if there are any spare array LUNs, or if the V_StorageAttach license is installed.
