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.
- Provide an external disk storage device mount point.
-
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
- Change the var/abu_storage/<mount point directory> owner to abuservice. # chown -R abuservice /var/abu_storage/<mount point directory>
-
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
-
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
