Supported Snapshot Manager for Data Center operations on Lenovo DM 5000 models
NetBackup Snapshot Manager for Data Center performs the following snapshot management operations on the Lenovo DM array:
Note:
In the case of Lenovo DM, a LUN is part of a volume and the action performed on a single LUN is performed on it's entire parent volume internally. Therefore, a volume acts as a consistency group.

Snapshot Manager for Data Center operations | Description |
|---|---|
Discover assets | NetBackup Snapshot Manager for Data Center discovers the volume, LUNs that are created from storage volumes.
|
Create snapshot | NetBackup Snapshot Manager for Data Center takes a snapshot of the Lenovo DM volumes and LUNs

Export snapshot | When a snapshot export operation triggers for a LUN Snapshot Object, NetBackup Snapshot Manager for Data Center creates a LUN clone from the snapshot and attaches it to the target. When a snapshot export operation triggers for a Volume Snapshot Object, NetBackup Snapshot Manager for Data Center creates a volume clone from the snapshot and attaches all the LUNs associated with the volume to the target. The target host is assigned with the read-write privileges on the exported entity (Volume/ LUN). The export operation is supported using the following protocols:
When a snapshot export operation is triggered, for NFS, export policy rules are checked for source volume. If the export rules match the client (selected in the policy) which includes protocols as NFS or SMB or both with superuser access. Then the backup is performed directly on the client. If no export rule match is found, then a new rule with the NFS protocol, read-only with superuser access, is created in the export policy and assigned to the export snapshot. For the SMB protocol, a new share is created with read permission, which includes the path of the snapshot. This share name is created with a name, and a snapshot name prefix. Example: NB<unique_21digit_number>-432464523 |
