Study Notes
Decommissioning a Media Server
- To decommission a media server, use the NetBackup
nbdecommissioncommand, which removes references to the media server from the NetBackup domain. - The command launches a text-based wizard that guides you through the decommission process.
- The
nbdecommissioncommand helps in scenarios such as:- Retiring a server that is no longer required.
- Replacing an old server with a new server and keeping the same storage.
- Accessing old server storage and backup images from the new server.
- Replacing a failed server with a new server.
- Cleaning up remaining references to a media server after manual decommissioning.
Previewing References to a Media Server
- Run the
nbdecommissioncommand with the-list_refoption to preview references to the media server. - The command syntax is:
nbdecommission -list_ref -oldserver OldServer > file.txt - Replace
OldServerwith the name of the host to be decommissioned andfilewith a name that denotes its contents or purpose. - Analyze the output to ensure that the command captures all references to the old server.
Removing a Device Host from the EMM Database
- Use the NetBackup Administration Console to remove a device host from the Enterprise Media Manager (EMM) database.
- In the console, expand
Media and Device Management > Devices > Media Servers, select the host, and then selectEnterprise Media Manager Database > Remove Device Host.
Procedures for Decommissioning a Media Server
- Two procedures exist:
- Replace an old media server with a new media server.
- Decommission a media server.
- To replace an old media server with a new media server, run the
nbdecommissioncommand with the-oldserverand-newserveroptions. - To decommission a media server, run the
nbdecommissioncommand with the-oldserveroption.
Command Syntax and Options
- The command syntax is:
- On Windows:
install_path\NetBackup\bin\admincmd\nbdecommission -oldserver OldServer [-newserver NewServer] [-file decom_ops.txt] - On UNIX:
/usr/openv/netbackup/bin/admincmd/nbdecommission -oldserver OldServer [-newserver NewServer] [-file decom_ops.txt]
- On Windows:
- Options:
-
-oldserver: specifies the name of the host to be decommissioned. -
-newserver: specifies the name of the new server (optional). -
-file: specifies the file to write the command operations to (optional).
-
Post-Decommission Recommendations
- Follow the instructions provided by the
nbdecommissioncommand. - Move physical storage (if necessary) and reconfigure devices.
- Examine the
vm.conffiles on all NetBackup servers and remove references to the old server. - Remove the old server from the server lists on clients and add the new server where necessary.
- Back up the NetBackup catalog as soon as possible.
Decommissioning Limitations
- The
nbdecommissioncommand does not decommission clustered media servers. - The command does not process Media Server Deduplication Pools.
- The command does not update
vm.conffiles on NetBackup servers or configuration files on clients. - The command does not notify about orphaned resources.
- The command does not restart daemons and services on other servers that are affected by the decommissioning.### Decommissioning a Media Server
- To decommission a media server, run the
nbdecommissioncommand on the primary server or on a media server that is not the object of this operation. - The command logs to the standard NetBackup administrator commands log directory.
- Two procedures exist: replacing an old media server with a new one, and decommissioning a media server.
Replacing an Old Media Server with a New One
- Run the
nbdecommissioncommand with the-oldserverand-newserveroptions to replace an old media server with a new one. - The command may make changes on the primary server and on multiple media servers.
- You may be required to restart the NetBackup services on those servers so that the changes take effect.
Registering a Media Server
- To register a media server, start the EMM service on the primary server and run the
nbemmcmdcommand with the-addhostoption. - The command requires the host name of the media server and other details such as the master server, operating system, and NetBackup version.
Deleting Devices from a Media Server
- You can delete all devices from a media server using the
nbemmcmdcommand with the-deletealldevicesoption. - The media server can be up, down, or failed and unrecoverable.
- You can also delete disk pools from a media server using the
nbdevconfigcommand.

- Helps maintain device performance through regular maintenance.
- Helps organizations meet compliance requirements.
- Can help avoid costly downtime due to technical issues.
- Allows administrators to track how devices are used within an organization.### Device Management
- Device management refers to the process of managing IT devices within an organization's network to ensure optimal performance, security, and compliance with company policies.
- Involves assigning specific roles and permissions to each device, monitoring usage, applying software updates, enforcing security protocols, and removing outdated equipment.
Importance of Device Management
- Ensures secure access to sensitive data and prevents unauthorized access to devices.
- Maintains regulatory compliance, avoiding legal repercussions and fines.
- Automates repetitive tasks, reducing workload and improving operational efficiency.
- Ensures minimal disruptions, allowing employees to stay productive.
- Helps prevent unexpected expenses from hardware failures, security breaches, or noncompliance issues.
Benefits of Device Management
- Provides control over devices, ensuring they are up to date and compliant.
- Enforces security protocols, protecting against unauthorized access, malware, and data breaches.
- Enables mass deployment of software updates and security patches across the network.
- Reduces downtime and maintains system uptime.
- Simplifies management with a centralized platform for managing multiple devices.

- Follow post-decommission recommendations, including examining vm.conf files and removing references to the old server.
Configuring Credentials
- Credentials are only visible when a feature that requires external credentials is licensed
- The Media and Device Management > Credentials section is used to manage log on credentials for various features
Credentials Management
- Cloud storage credentials are configured when setting up the storage server
- NetBackup Deduplication Engine credentials are created when configuring the storage server
- NDMP hosts require credential configuration
- OpenStorage storage servers require credential configuration when setting up the storage server
- Virtual machine server credentials are configured for NetBackup for VMware
- WebSocket Server credentials are configured for NetBackup WebSocket Service (NBWSS)
- Nutanix Acropolis Cluster credentials require configuration
Configuring Snapshot Management Server in NetBackup
- The Snapshot Manager server can be configured as a snapshot management server in NetBackup.
- To configure the Snapshot Manager server, you need to add the credentials of the Snapshot Manager server.
- There are three ways to configure the Snapshot Manager server:
Configuration Methods
- Using the NetBackup Administration Console
- Using the tpconfig command line, as explained in the NetBackup Commands Reference Guide
- Using the NetBackup WebUI, as explained in the NetBackup Web UI Cloud Administrator's Guide
NAT Support in NetBackup
- NetBackup supports clients and servers in a private network connected to NetBackup servers in a public network via a device that performs Network Address Translation (NAT).
- NAT clients and NAT servers together are referred to as NAT hosts.
Conditions for NAT Support
- A NAT host must be able to resolve the host names of the NetBackup servers and initiate connections with them.
- The NetBackup servers do not need to initiate connections to the NAT host.
- A host name assigned to a NAT host must be resolvable in the private network.
- The host name of the NAT host does not need to be resolvable from the NetBackup servers in the public network.
- Bi-directional connectivity is required between the primary server and all media servers, and between media servers and clients behind NAT.
NetBackup Software Configuration
- The NetBackup software on the NetBackup servers and NAT hosts must be configured for NAT support.
- NetBackup software ensures that all network connections are initiated from the NAT client to the NetBackup servers in the public network.
NAT Host Support
- NetBackup relies on a new NetBackup Messaging Broker (nbmqbroker) service on the primary server and a subscriber service on each NAT host.
- The subscriber service maintains a persistent connection to the messaging broker service on the primary server.
- The NetBackup servers send commands to the NAT hosts via the messaging service.
Connection between Media Server and NAT Client
- A media server sends a 'reverse connection request' message to the NAT host via the primary server.
- The NAT client initiates a connection to the requesting NetBackup server on receiving the message.
Workflow to Enable NAT Hosts
- The NetBackup Messaging Broker (nbmqbroker) service starts on the primary server if NAT support is enabled.
- The subscriber service starts on the NAT host along with other client services and subscribes to nbmqbroker service on the primary server if NAT support is enabled.
Use Cases for NAT Support
- NetBackup NAT support can be used in non-NAT environments where clients need to initiate connections to the NetBackup servers.
- Examples include clients or servers behind a firewall, DHCP clients without Dynamic DNS, or clients or servers to which media servers or primary servers cannot directly connect.
