You must establish a mount point for each Teradata Database node that functions as an Appliance Backup Utility client. The following steps create a temporary NFS mount to each Teradata Database node from the Data Domain 4200, then create a separate directory folder for each temporary mount. After the folders have been created, the DD4200 can be mounted on each Teradata Database node.
-
From the Data Domain 4200 command-line interface, create a temporary mount and directory folder on a Teradata Database node.
In the following example, Node1 specifies a Teradata Database node.
Node1# mount –t nfs 192.168.1.xxx:/backup /mnt Node1# cd /mnt Node1# mkdir drive1 to drive12 or maximum directory you have selected. Umount /mnt
-
Log on to each Teradata Database node and:
-
Create a directory for each node and set the permission to 777.
In the following example, nodes 1 - 4 are Teradata Database nodes and disks 1 - 4 are the mount point directories.
Node1# mkdir /var/abu_storage/disk1 chmod 777 /var/abu_storage/disk1 Node2# mkdir /var/abu_storage/disk2 chmod 777 /var/abu_storage/disk2 Node3# mkdir/var/abu_storage/disk3 chmod 777 /var/abu_storage/disk3 Node4# mkdir /var/abu_storage/disk4 chmod 777 /var/abu_storage/disk4
-
Mount the Data Domain 4200.
The following example uses 10GB cable link.
Node1# mount –t nfs 192.168.xxx.xxx:/backup/drive1 /var/abu_storage/disk1 Node2# mount –t nfs 192.168.xxx.xxx:/backup/drive2 /var/abu_storage/disk2 Node3# mount –t nfs 192.168.xxx.xxx:/backup/drive3 Disk3 /var/abu_storage/disk3 Node4# mount –t nfs 192.168.xxx.xxx:/backup/drive4 /var/abu_storage/disk4
-
Create a directory for each node and set the permission to 777.
In the following example, nodes 1 - 4 are Teradata Database nodes and disks 1 - 4 are the mount point directories.
