Checklist for NetBackup Appliance high availability deployment
Use this checklist to prepare for deploying a new appliance high availability (HA) setup. The items appear in the order that you should follow when deploying a new HA installation. Put a mark in the Check column as you address each item.
Table: Checklist for HA deployment
1. Master server type
Determine the master server type to use. Supported master server types are as follows:
The master server must be configured and reachable on your network before you configure the compute node, the HA setup, and the partner node.
2. Compute node and partner node installation
Install the compute node and the partner node as described in the NetBackup 5330 Appliance Hardware Installation Guide or the NetBackup 5340 Appliance Hardware Installation Guide.
The following describes the order of the main installation tasks that must be done before you perform any initial configuration on the nodes and before you configure the HA setup:
3. HA host names and IP addresses
Determine the host names and the IP addresses for the virtual environment that encompasses the whole HA setup and the physical nodes:
4. Compute node configuration
Configure the compute node using the methods described in the NetBackup 53xx Appliance Initial Configuration Guide.
Be sure to enter the virtual host name and IP address during this configuration. When you start the HA setup configuration (Item 6), that process prompts you to enter a new host name and IP address for this node.
Do not create a bond on ports NIC3 (eth2) or NIC4 (eth3). These ports are required exclusively for HA connectivity and any existing bond prevents you from adding the partner node to the HA setup (Item 8). See the following article for more details:
5. Host name mapping updates
On the master server, log in to the NetBackup Administration Console and do the following:
If the compute node host name is not added to the host name mappings before you configure the HA setup and the partner node, the HA setup process can fail.
6. Start HA setup configuration
Before you start this task, check the following:
After these items have been addressed, configure the HA setup from the compute node as described in the NetBackup 53xx Appliance Initial Configuration Guide. Refer to the topic "Configuring a NetBackup 53xx high availability setup".
During the HA setup, the host name and the IP address of the compute node are elevated and become the virtual host name and IP address. When prompted, enter the host name and IP address for the compute node from Item 3.
7. Partner node configuration
Configure the partner node as described in the NetBackup 53xx Appliance Initial Configuration Guide. Refer to the topic "Performing the initial configuration on the partner node for a NetBackup 53xx high availability configuration".
Note the following about partner node configuration:
8. Complete HA setup with partner node
After the partner node has completed the reboot and you have run the storage scan command on both nodes, add the partner node to the HA setup as described in the NetBackup 53xx Appliance Initial Configuration Guide. Refer to the topic "Adding the partner node to the NetBackup 53xx high availability configuration".
Starting with appliance release 3.1.2, host name mappings also require approval. The procedure to add the partner node to the HA setup includes a step to approve the host name mappings.
9. Post HA deployment tasks
After you have completed the HA setup, check the following items and address them as described:
