Supported CloudPoint operations on Dell EMC Unity arrays
CloudPoint performs the following management operations on the Dell EMC Unity arrays.
Table: CloudPoint operations on Dell EMC Unity plug-in
CloudPoint operation | Description |
|---|---|
Discover assets | CloudPoint discovers all the volumes and their snapshots along with their storage group. Note: CloudPoint only discovers assets with depth as 2. |
Create snapshot | To create a snapshot, CloudPoint triggers an SDK method on the storage group within which the volumes reside, with the required information and snapshot name. A typical snapshot created by CloudPoint has the following naming convention: NB<unique_21digit_number> |
Delete snapshot | To delete a snapshot, CloudPoint triggers an SDK method with the required snapshot details and confirms that the snapshot has been deleted successfully on the array. |
Restore snapshot | CloudPoint offers the ability to restore with the help of SDK methods with different restore paths. |
Export snapshot | When a snapshot export operation is triggered, a new NFS export is created over the same filesystem path, on which the backups host is added as a client with read-only permissions |
Deport snapshot | When a snapshot deport operation is triggered, CloudPoint deletes the exported storage group created over the snapshot path and the volume inside it, and the temporary storage group that is used as a source. It essentially reverts the snapshot export operation. |
You can also perform the following CloudPoint operations on supported Dell EMC Unity arrays:
List all the disks.
Create a copy-on-write (COW) snapshot of a LUN.
Note:
Snapshot name can be lowercase or uppercase, can contain any ASCII character, and can include special characters.
Delete a COW snapshot of a LUN.
Restore a LUN using a COW snapshot. The snapshot overwrites the original object.
Note:
You cannot snapshot LUNs which are under a consistency group. The reason for this limitation is that to restore a single LUN snapshot would restore the entire consistency group.
The following requirements and limitations are applicable in a Dell EMC Unity array environment:
The host on which the snapshot is to be exported must be attached to the array.
Note:
The exported snapshot is attached to the host and is accessible using a world wide name (WWN) that is assigned by the array.
Snapshot export is supported using the following protocols:
Fibre Channel (FC)
Internet Small Computer Systems Interface (iSCSI)
A snapshot cannot be exported multiple times.
An exported snapshot cannot be deleted.
