Installation and configuration prerequisites
Installation prerequisites
In addition to the installation prerequisites covered in the Quest NetVault Backup Plug‑in for NDMP User’s Guide, verify that the following requirements are met:
|
• |
Hardware requirements: For information about NetApp filers, see the NetApp website at: www.netapp.com |
|
• |
Software requirements: For information about software requirements and supported filer operating systems, see the Quest NetVault Backup Compatibility Guide available at: https://support.quest.com/technical-documents |
|
• |
Start the NDMP Daemon: To start the NDMP Daemon: |
|
• |
At the prompt, type: ndmpd on |
|
• |
Alternatively, to start the daemon automatically at boot time, open the file /etc/rc on the filer, and add: ndmpd on |
|
NOTE: The installation and configuration procedures are described in the Quest NetVault Backup Plug‑in for NDMP User’s Guide. |
Configuration prerequisites
In addition to the configuration prerequisites covered in the Quest NetVault Backup Plug‑in for NDMP User’s Guide, verify that the following requirements are met:
|
• |
To run NDMP backup using the CAB extension, verify that the following requirements are met:
|
• |
Review the software requirements: To use the CAB extension, you require NetVault Backup 10.0.5 or later, Plug‑in for NDMP 10.0.5 or later, and NetApp Data ONTAP 8.2.2 C-Mode or later. |
For information about software requirements, see the Quest NetVault Backup Compatibility Guide available at: https://support.quest.com/technical-documents
|
• |
Set the NDMP Service to Storage Virtual Machine (SVM)-scoped mode on the filer: Verify that the NDMP service is set to SVM-scoped mode. In Data ONTAP 8.1 and earlier versions, you must explicitly disable the node‑scoped mode for NDMP. |
|
• |
Verify the NDMP mode status: system services ndmp node-scope-mode status |
|
• |
Disable node-scoped mode: system services ndmp node-scope-mode off |
|
• |
Configure an NDMP service user account: In the SVM-scoped NDMP mode, you must use NDMP Service user account to access a storage system to perform tape backup and restore operations. You must also generate a password for the user account: |
|
• |
Add the Logical Interface (LIF) to the plug-in: To add the NDMP Client to the plug-in, use the IP address of the Logical Interface (LIF) and the NDMP service user account. |
You can use the command network interface show to obtain information about LIFs. The availability of volumes and tape devices depends on the LIF type that you use.
|
Tape devices connected to the node hosting the node management LIF | ||
For more information about the availability of volumes and tape devices, see the Clustered Data ONTAP Data Protection Tape Backup and Recovery Guide.
|
• |
Set the NDMP Service to node-scoped mode: Verify that the NDMP service is set to node-scoped mode. In a new clustered Data ONTAP 8.2 installation, NDMP is in SVM-scoped mode by default. |
|
• |
Verify the NDMP mode status: system services ndmp node-scope-mode status |
|
• |
Enable node-scoped mode: system services ndmp node-scope-mode on |
|
• |
Configure NDMP root password on cluster nodes: In the node-scoped NDMP mode, you must use an NDMP-specific user account to access a storage system to perform tape backup and restore operations. User authentication must be configured on each node. The default user ID is root. Ensure that you change the default NDMP password associated with the root user account. |
|
• |
Set user password: system services ndmp modify -node * -clear-text false ‑user-id root -enable true |
|
• |
Verify the configuration using the following command: system services ndmp show |
|
• |
Create the LIF and add the LIF to the plug-in: To add the NDMP Client to the plug-in, use the IP address of the LIF and the NDMP root user account. |
|
• |
Create the LIF: network interface create -vserver vnetapp -lif For_Backup -role cluster-mgmt -home-node vserver-01 -home-port e0d -address 192.168.0.22 -netmask 255.255.255.0 |
|
• |
Verify the configuration of the LIF: net int show -fields role,data,data-protocol,vserver,address,curr-node,curr-port |
|
NOTE: If a volume affinity changes to a different node, you must manually migrate the LIF to the node that is now hosting the volume: net int migrate -vserver vserver1 -lif For_Backup -dest-node vserver1‑02 -dest‑port e0d |
To use the NDMP root user account for accessing the filer, set a valid password for this account. Password cannot be left blank for this user account. To use a nonroot user, verify that the account has necessary privileges to perform NDMP backups and restores.
Changing from NDMP node-scoped mode to NDMP SVM-scoped mode
After changing from NDMP node-scoped mode to NDMP SVM-scoped mode, complete the following tasks:
|
• |
Add the tape libraries and drives to the NetVault Backup Server again. For more information, see the Quest NetVault Backup Administrator’s Guide. |
|
• |
Create the Target Sets again. For more information, see the Quest NetVault Backup Administrator’s Guide. |
|
• |
Modify the IP address for the NDMP Client. In the SVM-scoped mode, you must use the IP address of the LIF. For more information about editing the IP address, see the Quest NetVault Backup Plug‑in for NDMP User’s Guide. |
|
• |
Create the Backup Selection Sets again if there is any change in the NDMP Client name. For more information, see the Quest NetVault Backup Administrator’s Guide. |
