Setting a storage volume rebuild type
About this task
For XtremIO, VNX and VMAX arrays, metro node automatically detects if a storage volume is thin capable. For all other arrays,
metro node does not automatically detect if a storage volume is thinly-provisioned on the array. Therefore, if a storage volume
is thinly-provisioned, or thin capable, choose a thin rebuild. When you select a thin rebuild, metro node preserves the thinness of
the target device by copying only non-zero data.
You can specify the type of rebuild for a storage volume when you claim the storage (from the Storage Arrays view), or you
can do so later by selecting claimed storage volumes (Storage Volumes view). Note that the claimed storage volumes may be
in use. The change takes effect immediately.
NOTE: For thin capable storage volumes, metro node will automatically select a thin rebuild even if you did not select this
option in the wizard during the claiming process.
Steps
1. From the GUI main menu, do one of the following:
● In a metro node Local:
a. Select Provision Storage.
b. In the View by drop-down, select Storage Volumes.
● In a metro node Metro:
a. Select Provision Storage.
b. In the Provision on drop-down, select the cluster of the storage volume.
c. In the View by drop-down, select Storage Volumes.
2. Select the storage volume, and then select MORE > Set Rebuild Type.
The Set Claimed Volumes Rebuild Type dialog box opens.
3. Select Yes under Use Thin Rebuilds.
4. Click OK.
Unclaiming a storage volume
About this task
Storage volumes are either discovered on the array, or created from storage pools. Regardless of how a storage volume was
created, when you unclaim it, the status changes to Unclaimed, making it available for claiming again. However, if the storage
volume was created from a storage pool, you have the option of deleting the storage volume from the array and returning the
allocated storage capacity to the pool on the array. You can select multiple storage volumes to unclaim, and the selection can
contain a mix of storage volumes created with and without integrated services.
NOTE: You cannot unclaim a storage volume that is currently in use.
Steps
1. From the GUI main menu, do one of the following:
● In a metro node Local:
a. Select Provision Storage.
b. In the View by drop-down, select Storage Volumes.
● In a metro node Metro:
a. Select Provision Storage.
b. In the Provision on drop-down, select the cluster of the storage volume.
c. In the View by drop-down, select Storage Volumes.
2. Select one or more claimed storage volumes, and then select MORE > Unclaim Storage.
A confirmation dialog box is displayed.
● If the confirmation box displays a check box, this means that your selection contains at least one storage volume created
from a storage pool. Select the check box to delete the storage volume on the array and return the storage capacity of
those storage volumes to the pool from which they were created.
● If the confirmation box does not contain a check box, click Yes.
