Supported Snapshot Manager for Data Center operations on Dell EMC Unity arrays
CloudPoint performs the following management operations on the Dell EMC Unity arrays.
Table: Snapshot Manager for Data Center operations on Dell EMC Unity plug-in
Snapshot Manager for Data Center operation | Description |
|---|---|
Discover assets | Snapshot Manager for Data Center discovers all the volumes and their snapshots along with their storage group. Note: Snapshot Manager for Data Center only discovers assets with depth as 2. |
Create snapshot | To create a snapshot, Snapshot Manager for Data Center 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 Snapshot Manager for Data Center has the following naming convention: NB<unique_21digit_number> |
Delete snapshot | To delete a snapshot, Snapshot Manager for Data Center 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, Snapshot Manager for Data Center 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 Snapshot Manager for Data Center 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.
