Veritas NetBackup™ for Microsoft SQL Server Administrator's Guide

Reviewing the auto-discovered mappings in Host Management

In certain scenarios, a NetBackup host shares a particular name with other hosts or has a name that is associated with a cluster. To successfully perform backups and restores with NetBackup for SQL Server, you must approve each valid Auto-Discovered Mapping that NetBackup discovers in your environment. These mappings appear in the Host Management properties on the master server. You can also use the nbhostmgmt command to manage the mappings. See the NetBackup Administrator's Guide, Volume I for more details on Host Management properties.

Examples of the configurations that have multiple host names include:

  • A host is associated with its fully qualified domain name (FQDN) and its short name or its IP address.

  • If the SQL Server is clustered, the host is associated with its node name and the virtual name of the cluster.

Auto-discovered mappings for a cluster

In a SQL Server cluster environment, you must map the node names to the virtual name of the cluster if the following apply:

  • If the backup policy includes the cluster name (or virtual name)

  • If the NetBackup client is installed on more than one node in the cluster

    If the NetBackup Client is only installed on one node, then no mapping is necessary.

To approve the auto-discovered mappings for a cluster

  1. In the NetBackup Administration Console, expand Security Management > Host Management.
  2. At the bottom of the Hosts pane, click the Mappings for Approval tab.

    The list displays the hosts in your environment and the mappings or additional host names that NetBackup discovered for those hosts. A host has one entry for each mapping or name that is associated with it.

    For example, for a cluster with hosts client01.lab04.com and client02.lab04.com, you may see the following entries:

    Host

    Auto-discovered Mapping

    client01.lab04.com

    client01

    client01.lab04.com

    clustername

    client01.lab04.com

    clustername.lab04.com

    client02.lab04.com

    client02

    client02.lab04.com

    clustername

    client02.lab04.com

    clustername.lab04.com

  3. If a mapping is valid, right-click on a host entry and click Approve.

    For example, if the following mappings are valid for client01.lab04.com, then you approve them.

    Auto-discovered Mapping

    Valid name for

    client01

    The short name of the client

    clustername

    The virtual name of the cluster

    clustername.lab04.com

    The FQDN of the virtual name of the cluster

  4. When you finish approving the valid mappings for the hosts, click on the Hosts tab at the bottom of the Hosts pane.

    For hosts client01.lab04.com and client02.lab04.com, you see Mapped Host Names/IP Addresses that are similar to the following:

    Host

    Mapped Host Names/IP Addresses

    client01.lab04.com

    client01.lab04.com, client01, clustername, clustername.lab04.com

    client02.lab04.com

    client02.lab04.com, client02, clustername, clustername.lab04.com

  5. If you need to add a mapping that NetBackup did not automatically discover, you can add it manually.

    Click on the Hosts tab, then right-click in the Hosts pane and click Add Shared or Cluster Mappings. For example, provide the name of the virtual name of the cluster. Then click Select Hosts to choose the node names in the cluster to which you want to map that virtual name.

Auto-discovered mappings for a SQL Server cluster in a multiple NIC environment

If you have a SQL Server cluster in a multi-NIC environment, you need to approve each valid Auto-Discovered Mapping for the hosts in that environment. You must map the virtual name of the SQL Server cluster on the private network to the private name of each SQL Server cluster node.

To approve the auto-discovered mappings for a SQL Server cluster in a multiple NIC environment

  1. In the NetBackup Administration Console, expand Security Management > Host Management.
  2. At the bottom of the Hosts pane, click the Mappings for Approval tab.

    The list displays the hosts in your environment and the mappings or additional host names that NetBackup discovered for those hosts. A host has one entry for each mapping or name that is associated with it.

    For example, for a cluster in a multi-NIC environment with hosts client01-bk.lab04.com and client02-bk.lab04.com, you may see the following entries:

    Host

    Auto-discovered Mapping

    client01-bk.lab04.com

    clustername-bk.lab04.com

    client02-bk.lab04.com

    clustername-bk.lab04.com

  3. If a mapping is valid, right-click on a host entry and click Approve.

    For example, if following mapping is valid for client01-bk.lab04.com, then you approve it.

    Auto-discovered Mapping

    Valid name for

    clustername-bk.lab04.com

    The virtual name of the SQL Server cluster on the private network

  4. When you finish approving the valid mappings for the hosts, click on the Hosts tab at the bottom of the Hosts pane.

    For hosts client01-bk.lab04.com and client02-bk.lab04.com, you may see the following Mapped Host Names/IP Addresses.

    Host

    Mapped Host Names/IP Addresses

    client01-bk.lab04.com

    clustername-bk.lab04.com

    client02-bk.lab04.com

    clustername-bk.lab04.com

  5. If you need to add a mapping that NetBackup did not automatically discover, you can add it manually.

    Click on the Hosts tab, then right-click in the Hosts pane and click Add Shared or Cluster Mappings. For example, provide the name of the virtual name of the cluster. Then click Select Hosts to choose the hosts to which you want to map that virtual name.
