Supported Snapshot Manager for Data Center Operation on Fujitsu AX/HX array

You can perform the following Snapshot Manager for Data Center operations supported on Fujitsu AX/HX array:

Note:

In the case of Fujitsu AX/HX, a LUN is part of a volume and the action performed on a single LUN is performed on its entire parent volume internally. Therefore, a volume acts as a consistency group.

Table: Snapshot Manager for Data Center operations on the Fujitsu AX/HX array

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. LUNs that have an online status and read-write operations are enabled can be discovered. During the discovery of assets, the plug-in creates a mapping between volumes and LUNs. Only online volumes are discovered. Snapshot Manager for Data Center discovers all the NAS volumes that are online and using the active junction path on the Fujitsu AX/HX storage. Junction-Path specifies the access protocol for either NFS or SMB.
Create snapshot	Snapshot Manager for Data Centertakes a snapshot of the Fujitsu AX/HX volumes and LUNs To create a LUN snapshot on the Fujitsu AX/HX storage, the array internally initiates a Redirect-on-Write (ROW) snapshot of the entire volume to which the LUN belongs. If the volume contains multiple LUNs, the snapshot includes data from the LUNs that reside on the associated volume. When a volume snapshot is initiated on the Fujitsu AX/HX storage, creates a ROW snapshot of the entire volume and returns the snapshot data of the volume. Snapshot Manager for Data Center takes a snapshot of the Fujitsu AX/HX NFS and SMB share using volume. A snapshot created with the following naming convention: : NB<unique_21digit_number>
Delete snapshot	When a delete snapshot operation is initiated for the following: LUN snapshot - NetBackup Snapshot Manager for Data Center internally deletes the snapshot of one or more volumes to which the LUN is associated. Volume snapshot - NetBackup Snapshot Manager for Data Center deletes the snapshot corresponding to the volume. Snapshot Manager for Data Center deletes the snapshot of the NAS volume.
Deport snapshot	When a deport snapshot operation is initiated for the following: LUN Deport - Snapshot Manager for Data Center removes the LUN mapping from the target host and then deletes the LUN clone. Volume deport - Snapshot Manager for Data Center removes the mapping from the LUN hosts associated with the volume and then deletes the volume clone. When a snapshot deport operation is initiated for SMB, Snapshot Manager for Data Center deletes the shares created during the export call. For NFS, no action is performed.
Export snapshot	When a snapshot export operation initiates for a LUN Snapshot Object, Snapshot Manager for Data Center creates a LUN clone from the snapshot and attaches it to the target. When a snapshot export operation initiates for a Volume Snapshot Object, 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: Fiber Channel (FC) Internet Small Computer Systems Interface (iSCSI) When a snapshot export operation is initiated, for NFS, export policy rules are checked for source volume. If the export rules match the client (selected in the policy) which includes protocol 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 NFS protocol, read-only with superuser access is created in the export policy and is assigned to the export snapshot. For SMB protocol, a new share is created with read permission which includes the path of the snapshot. This share name is created with the snapshot name prefix. Example: NB<unique_21digit_number>-432464523
Restore snapshot	When you restore a LUN from a snapshot, Snapshot Manager for Data Center restores the entire Volume of the LUN where the restore is triggered. The LUN snapshot is a ROW snapshot of the underlying volume and that volume can contain multiple LUN. Even if the restore is triggered for a single LUN, the restore is performed on the entire volume. Data on the other LUNs remains unchanged. The volume snapshot restores a snapshot copy to the read-write volume. If the current working copy of the volume is replaced with the snapshot copy. Then it results in loss of all changes made since the snapshot copy was created. Note: If the restore operation is performed on older snapshots. Then, all the latest snapshots captured are deleted as a part of Fujitsu AX/HX behavior and the latest snapshots cannot be restored.
