Reconfiguring IBM Storage Protect to optimize clustered backups

If you configured IBM Storage Protect to back up NetApp clusters by using node-scoped NDMP, you can reconfigure IBM Storage Protect to use NDMP Cluster Aware Backup (CAB). In this way, you can optimize backup operations for NetApp clusters.

Before you begin

For an overview of NDMP functionality in IBM Storage Protect and NetApp file servers, see technote 7046965. This technote also lists system requirements.

About this task

When you reconfigure IBM Storage Protect to use CAB, you can optimize backup operations in the following ways:
  • You can configure IBM Storage Protect to back up all volumes in a NetApp cluster to a directly attached tape device or to an IBM Storage Protect server. In both cases, the data is owned by a single IBM Storage Protect node. Even if you move volumes within the cluster, backup operations continue and no reconfiguration is required.
  • You can complete a partial backup of a NetApp cluster to an IBM Storage Protect server. This method is useful when multiple organizations own data in the cluster. Each organization can manage backup operations for its data. You set the scope of a partial backup by specifying a NetApp storage virtual machine (SVM), which provides access to part of a cluster.

To reconfigure IBM Storage Protect to use CAB, you must define a new IBM Storage Protect node and a new data mover.

Procedure

  1. Verify that NetApp Clustered Data ONTAP 8.2 or later, or 9.1 or later, is installed on the NetApp file server.
  2. Enable the use of NDMP by following the instructions in the Clustered Data ONTAP® Data Protection Tape Backup and Recovery Guide. Take one of the following actions:
    For a full cluster backup
    Complete the following steps:
    1. Enable SVM-scoped NDMP backup operations at the cluster level. In this way, you disable node-scoped NDMP backup operations on the NAS file server. Ensure that the node-scoped-ndmp option on the NAS file server is set to OFF.
    2. Create a backup user ID for NDMP operations.
    3. Configure a network interface for NDMP control connections at the cluster level.
    For a partial cluster backup
    Complete the following steps:
    1. Enable SVM-scoped NDMP to control NDMP backup operations.
    2. Create a backup user ID for NDMP operations.
    3. Configure a network interface for NDMP control connections at the SVM level.
  3. Register the IBM Storage Protect node that will own the backup data. On the IBM Storage Protect server, issue the REGISTER NODE command:
    register node node_name password domain=nas_domain type=nas
    where node_name specifies the node name, password specifies the node password, and nas_domain specifies the domain of the node.
  4. If you plan to back up a full cluster, determine the IP address of the NetApp cluster management interface on the NAS file server. The interface provides access to the entire cluster. On the NAS file server, issue the following Data ONTAP operating system command:
    network interface show -role cluster-mgmt
    The IP address in the output is required when you specify the HLADDRESS parameter in step 6.
  5. If you plan to back up a partial cluster, determine the numerical IP address or the domain name of the cluster interface that is used by the SVM. To determine the value, issue the following Data ONTAP operating system command on the NAS file server:
    network interface show -vserver vserver_name -role data
    where vserver_name specifies the name of the SVM. The value that you obtain is required in step 6.
  6. Define a data mover for the IBM Storage Protect node. Take one of the following actions:
    For a full cluster backup
    Define a data mover for the IBM Storage Protect node that will own the backup data. On the IBM Storage Protect server, issue the DEFINE DATAMOVER command on one line:
    define datamover data_mover_name type=nascluster
    hladdress=cluster_management_interface lladdress=port 
    USER=user_name password=password dataformat=netappdump
    where cluster_management_interface is the value that you obtained in step 4 and data_mover_name is the node name that you registered in step 3.
    Tip: After you define the data mover, additional data movers are defined automatically for each node in the cluster. The name of each data mover matches the name of the physical node in the cluster. You will use these data movers when you define paths to tape drives that are attached to the cluster.
    For a partial cluster backup
    Define a data mover for the node by issuing the DEFINE DATAMOVER command and specifying TYPE=NASVSERVER. On the IBM Storage Protect server, issue the following command on one line:
    define datamover data_mover_name type=nasvserver
    hladdress=svm_data_interface lladdress=port 
    USER=user_name password=password dataformat=netappdump
    where svm_data_interface is the value that you obtained in step 5 and data_mover_name is the node name that you registered in step 3.
    For information about specifying the other parameters on the DEFINE DATAMOVER command, see DEFINE DATAMOVER (Define a data mover).
  7. To back up data to a directly attached tape device, for each tape drive that is attached to the cluster, identify the device name and the physical node to which the drive is attached:
    1. On the NAS file server, issue the following Data ONTAP command:
      storage tape show-tape-drive
    2. Review the output to find the serial number of the tape drive, and the node of the cluster to which the drive is attached. The same stanza includes the device name, for example, st1, st2, or st3.
  8. To configure a full cluster backup to a directly attached tape device, follow the instructions in Configuring tape devices for full cluster backups.
  9. To configure a full or partial cluster backup to an IBM Storage Protect server, configure a policy for managing NAS image backups. Follow the instructions in Configuring an IBM Storage Protect policy for NDMP operations.
  10. Disable scheduled backup operations for all nodes that were previously used to back up the NetApp cluster.
  11. Identify the volumes in the cluster and optionally schedule backup operations for the volumes. Take one of the following actions:
    For a full cluster backup
    1. On the NAS file server, identify the volumes in the cluster by using the following Data ONTAP command:
      volume show
    2. Run a full backup of the entire cluster.
    3. Optional: To schedule backup operations, follow the instructions in Scheduling NDMP operations.
    For a partial cluster backup
    1. On the NAS file server, identify the volumes in the cluster by using the following Data ONTAP command:
      volume show -vserver vserver_name
      where vserver_name specifies the name of the SVM.
    2. Run a full backup of the partial cluster.
    3. Optional: To schedule backup operations, follow the instructions in Scheduling NDMP operations.

What to do next

To verify that volumes in the NetApp cluster are backed up, complete the following steps:
  1. On the Operations Center menu bar, click Clients.
  2. Double-click a NAS device client and click Volumes.
  3. To determine when the last full volume backup was completed, review the information in the Last Full column. To determine when the most recent differential backup was completed, review the information in the Last Differential column.
