Supported CloudPoint operations on Dell EMC Unity arrays
You can 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.
Export snapshot
When a snapshot is exported, CloudPoint attaches the snapshot to the target host and keeps a track of it using the export ID.
Deport snapshot
When a snapshot is deported, CloudPoint detaches the exported snapshot from the target host and removes the export ID.
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.
