IPv6 support in NetWorker 19.3 and later

NetWorker 19.3 and later supports Internet Protocol version 6 (IPv6) addresses defined by RFC2732 in a pure IPv6 environment along with dual stack. IPv6 address can be used in place of FQDN and alias values in all NetWorker operations. The following areas use IP address, FQDN, and alias as input, where IPv6 address can be specified:

  • Client configuration:
    • NMC Client Configuration Wizard- This does not support square brackets. For example, Client Name:x:x:x:x:x:x:x:x
    • NMC Client properties- This supports both with and without square brackets. For example, Name:x:x:x:x:x:x:x:x, Name:[x:x:x:x:x:x:x:x]
    • CLI-nsradmin- This supports both with and without square brackets. For example, name:"x:x:x:x:x:x:x:x", name:"[x:x:x:x:x:x:x:x]"
  • Device configuration
    • Data Domain Device
      • Using NMC Device Configuration Wizard- Adding of a Data Domain system during device configuration. Without square bracket is only supported. For example, Add a new Data Domain system - x:x:x:x:x:x:x:x

      • Using NMC Device Properties- The remote storage node name and the device name needs to be enclosed in square brackets in the Data Domain Device Name. For example,
        • Data Domain Device Name- rd=[x:x:x:x:x:x:x:x]:[x:x:x:x:x:x:x:x]_DD_Device
        • Device Access Information- x:x:x:x:x:x:x:x:/<server_name>/DD_Device
      • Using CLI - nsradmin- For example,
        • Data Domain Device Name- rd=[x\:x\:x\:x\:x\:x\:x\:x]\:[x\:x\:x\:x\:x\:x\:x\:x]_DD_Device;
        • Device Access Information- "x:x:x:x:x:x:x:x:/<server_name>/DD_Device";
    • Advanced File Type Device
      • Using NMC Device Configuration Wizard- For example,
        • On an NFS share, without square bracket is only supported. Network Path is x:x:x:x:x:x:x:x:/data/col1/testnfs
        • On a CIFS share, without square bracket is only supported. Network Path is

          \\x-x-x-x-x-x-x-x.ipv6-literal.net\x$

      • Using NMC Device Properties- On an NFS share, provide the Device Access Information and the name in square brackets. For example,
        • Name- rd=[x:x:x:x:x:x:x:x]:AFTD_Device
        • Device Access Information- [x:x:x:x:x:x:x:x]:/data/col1/testnfs
        On a CIFS share, provide the name in square brackets. For example,
        • Name- rd=[x:x:x:x:x:x:x:x]:AFTD_Device
        • Device Access Information- \\x-x-x-x-x-x-x-x.ipv6-literal.net\x$
      • Using CLI- nsradmin- For example on an NFS share,
        • Name- rd=[x\:x\:x\:x\:x\:x\:x\:x]\:AFTD_Device;
        • Device Access Information- x\:x\:x\:x\:x\:x\:x\:x\:/data/col1/testnfs
        For example on a CIFS share,
        • Name- rd=[x\:x\:x\:x\:x\:x\:x\:x]\:AFTD_Device ;
        • Device Access Information- \\\\x-x-x-x-x-x-x-x.ipv6-literal.net\\x$;
  • Storage Node Configuration -
    • NMC- For example, Name:x:x:x:x:x:x:x:x, Name:[x:x:x:x:x:x:x:x]
    • CLI - nsradmin- For example, name:"x:x:x:x:x:x:x:x", name:"[x:x:x:x:x:x:x:x]"
  • -s <NetWorker Server IPv6 address> option is all NetWorker commands and utilities.
  • Client and Server Cluster configuration is supported for pure IPv6 and dual stack environment. However, even if you use the IPv6 address and FQDN while configuring the virtual IP, the NMC will always take the FQDN for the server’s client instance.
  • Backward Compatibility is supported for clients.
  • Bare Metal Recovery is supported in both pure IPv6 and Dual stack environment.

  • In an IPv6 enabled VMware environment, the following components should not have any unreachable IPv4 entries in the DNS server:
    • NetWorker server FQDN
    • vProxy appliance FQDN
    • Data Domain FQDN
    • vCenter FQDN
    • ESXi FQDN

    The FQDNs listed above should return only AAAA records from the DNS and should not have any unreachable IPv4 records in the DNS.

  • REST API- To launch NetWorker RESTAPI using IPv6 address, the address should be enclosed in "[]" brackets. For example, https://[x:x:x:x:x:x:x:x]:9090/nwrestapi. Here are some examples of using IPv6 addresses for various configurations.
    NOTE:"[] "should not be used in the API payloads
    • Client configuration-
      POST https://[ x:x:x:x:x:x:x:x]:9090/nwrestapi/v3/global/clients
      {
          "aliases": ["Windows-client"],
          "backupType": "Filesystem",
          "blockBasedBackup": false,
          "hostname": "x:x:x:x:x:x:x:x",
          "parallelSaveStreamsPerSaveSet": true,
          "parallelism": 4,
          "protectionGroups": ["MyGroup"],
          "remoteAccessUsers": [],
          "saveSets": ["C:\\MySavesets"],
          "scheduledBackup": true
          }
      
    • vProxy Registration-
      POST https://[ x:x:x:x:x:x:x:x]:9090/nwrestapi/v3/global/vmware/vproxies
      {
      "enabled": true,
      "hostname": "x:x:x:x:x:x:x:x",
      "maxHotaddSessions": 13,
      "maxNbdSessions": 13,
      "userName": "admin",
      "vCenterHostname": "fqdn.domainname.com",
      "password":"password",
      "vProxyPort": 9090
      }
      
    • Data Domain Device Configuration-
      POST https://[ x:x:x:x:x:x:x:x]:9090/nwrestapi/v3/global/devices
            {    
                  "deviceAccessInfo": "x:x:x:x:x:x:x:x:<folder structure>",
                  "mediaType": "Data Domain",
                  "name": "RESTAPI",
                  "password": "password",
                  "remoteUser": "remoteuser"
              }
      

Standard URL strings which contain IPv6 address should be enclosed by the "[" and "]" characters.

To launch NWUI through IPv6 address, the address should be enclosed in "[]" brackets. For example, https://[x:x:x:x:x:x:x:x]:9090/nwui.
NOTE:During NWUI installation, user can provide IPv6 address or hostname for the authentication server and NetWorker server if they are running on a IPv6 environment.
To launch NMC using IPv6 address, the address should be enclosed in "[]" brackets. For example, https://[x:x:x:x:x:x:x:x]:9000.
NOTE: During NMC configuration wizard, specify a list of IPv6 addresses or hostnames of NetWorker servers if they are running on a IPv6 environment.
