You must establish a mount point for each Teradata Database node that functions as an Appliance Backup Utility client.

The following steps must be performed on each node.

  1. Provide an external disk storage device mount point.
  2. Login to the Teradata Database node, create a directory, and set the permission to 777.

    In the following example, disks 1 - 4 are the mount point directories.

    # mkdir /var/abu_storage/disk1   chmod 777 /var/abu_storage/disk1
# mkdir /var/abu_storage/disk2   chmod 777 /var/abu_storage/disk2
# mkdir /var/abu_storage/disk3   chmod 777 /var/abu_storage/disk3
# mkdir /var/abu_storage/disk4   chmod 777 /var/abu_storage/disk4
  3. Change the var/abu_storage/<mount point directory> owner to abuservice. # chown -R abuservice /var/abu_storage/<mount point directory>
  4. Login to the shared mounted NFS target, create multiple directories, and set the permission to 777.

    In the following example, disks 1 - 4 are the shared target directories.

    # mkdir /srv/nfs4/drive1/disk1   chmod 777 /srv/nfs4/drive1/disk1
# mkdir /srv/nfs4/drive1/disk2   chmod 777 /srv/nfs4/drive1/disk2
# mkdir /srv/nfs4/drive1/disk3   chmod 777 /srv/nfs4/drive1/disk3
# mkdir /srv/nfs4/drive1/disk4   chmod 777 /srv/nfs4/drive1/disk4
  5. Mount the partition on the mount point directory. # mount <device partition 1> /var/abu_storage/<mount point directory>
    Teradata Corporation recommends using the read/write values in the following example, which uses Byn1-IP-Address. 
    Node1# mount -t nfs rw,rsize=1048576,wsize=1048576 
39.00.xxx.xxx:/srv/nfs4/drive1/disk1 /var/abu_storage/disk1
Node2# mount -t nfs rw,rsize=1048576,wsize=1048576 
39.00.xxx.xxx:/srv/nfs4/drive1/disk2 /var/abu_storage/disk2
Node3# mount -t nfs rw,rsize=1048576,wsize=1048576 
39.00.xxx.xxx:/srv/nfs4/drive1/disk3 /var/abu_storage/disk3
Node4# mount -t nfs rw,rsize=1048576,wsize=1048576 
39.00.xxx.xxx:/srv/nfs4/drive1/disk4 /var/abu_storage/disk4
    The following example uses 10GB cable link.
    Node1# mount -t nfs rw,rsize=1048576,wsize=1048576 
192.168.xxx.xxx:/srv/nfs4/drive1/disk1 /var/abu_storage/disk1
Node2# mount -t nfs rw,rsize=1048576,wsize=1048576 
192.168.xxx.xxx:/srv/nfs4/drive1/disk2 /var/abu_storage/disk2
Node3# mount -t nfs rw,rsize=1048576,wsize=1048576 
192.168.xxx.xxx:/srv/nfs4/drive1/disk3 /var/abu_storage/disk3
Node4# mount -t nfs rw,rsize=1048576,wsize=1048576 
192.168.xxx.xxx:/srv/nfs4/drive1/disk4 /var/abu_storage/disk4
  6. Enable NFS server in YAST command line:
