3.9.4.1.2 Create a Volume Clone Directly from an Existing Volume

Note:

To create an Exascale volume clone directly from an existing Exascale volume, you must use Oracle Exadata System Software release 25.1.0 or later.

To create a volume clone directly from an existing volume, use the ESCLI mkvolume command and specify the attributes for the volume clone. The command syntax is:

@> mkvolume --attributes volumeSource=parent_volume_id[,name=clone_name][,iopsProvisioned=integer_value][,iopsInherited={true|false}]

In the command:

• volumeSource=parent_volume_id: Identifies the existing volume that you want to clone. You can use the lsvolume command to find the identifier for each existing volume.

• name=clone_name: Optionally specifies the name of the volume clone, which makes it easier for you to identify later. If not specified, a system-generated name is assigned.

• iopsProvisioned=integer_value: Optionally specifies the I/O bandwidth provisioned for the volume clone. The I/O bandwidth is expressed as the number of I/Os per second (IOPS).

• iopsInherited={true|false}: Optionally specifies whether the volume clone inherits I/O bandwidth from the nearest ancestor in the volume hierarchy with provisioned (not inherited) I/O bandwidth.

For more details, see the mkvolume command reference.

After you create a volume clone, you must create an attachment to access the contents. By itself, an unattached volume clone is not available to any clients.
