Adding a node
Flex Appliance supports up to two nodes on the Veritas 5340 Appliance. You can add a second node during initial configuration or any time after.
A multi-node appliance provides the following benefits:
Increased efficiency with a shared workload
Automatic failover for a single-node failure
Adding a second node consists of the following tasks:
Perform the host network configuration on the new node.
From the existing node, add the new node to the appliance.
Complete the initial configuration on the new node.
To perform the host network configuration on the new node
Gather the following details for the new node that you want to add to the appliance:
Host IP address
Gather the following details from the appliance that you want to add the node to:
DNS server IP address
- Use the following steps to access the Flex Appliance Shell from the Veritas Remote Management Interface:
Open a supported web browser on a system that has a network connection to the appliance. Flex Appliance supports the following browsers:
Google Chrome version 57 or higher
Mozilla Firefox version 52 or higher
Enter the IP address that is assigned to the remote management port of the new node.
Log in to the Veritas Remote Management Interface with the following default credentials:
User Name: sysadmin
Change the sysadmin password from the known default password as follows:
Navigate to Configuration > Users and select the sysadmin user.
Click Modify User.
Select the Change Password check box and enter a new password.
Navigate to Remote Control > Console Redirection and click Launch Console to launch the Flex Appliance Shell.
- Log in to the Flex Appliance Shell with the following default credentials:
User Name: hostadmin
A welcome message appears in the Flex Appliance Shell with the available commands setup and system.
Before you begin the configuration, run a hardware test as follows:
Enter the following command to make sure that the node is available and functional:
Enter the following command to verify the storage volumes in the Primary Storage Shelf:
system hardware-health primaryshelf primaryshelf-component=volume
You should see six data LUNs in an OK state.
If you have one or more Expansion Storage Shelves, enter the following command for each shelf to verify the storage volumes:
system hardware-health expansionshelf shelf-ID=<ID> expansionshelf-component=volume
where <ID> is the ID for each expansion shelf.
You should see six data LUNs in an OK state.
If you encounter any errors during the hardware check, check the appliance cabling and disks to make sure that everything is connected properly. Make sure that you resolve any hardware errors before you proceed.
If the hardware check shows any disk or LUN errors, do not proceed with the configuration until those errors are resolved. These issues can cause performance degradation if they are not addressed.
- Enter the following command to configure the host network:
Follow the prompts to enter the host network information.
To add the new node to the appliance
- Log in to Flex Appliance Shell from the other, preexisting node that was previously configured for the appliance.
- From the preexisting node, enter the following command to add the new node to the appliance:
setup add-node with-response new_node=<hostname>, where <hostname> is the hostname of the node that you want to add.
When you are prompted for the new node's password, enter P@ssw0rd.
Do not perform any other tasks on the appliance until the add-node operation is complete.
To complete the initial configuration on the new node
- Log back in to the Flex Appliance Shell from the new node that you just added to the appliance. The shell should now display additional command options.
- Enter the following commands to change the hostadmin and root passwords from the known default password:
hostadmin: set user password
root: set user password user_name=root
Follow the prompts to enter the new passwords.
- Enter the following command to disable the root account on the new node:
system security root-disable
The root account is a restricted user account that can put the system at risk. It should only be enabled during initial configuration or under the direct supervision of Veritas Technical Support.
- If you added this node as part of the appliance initial configuration, return to the initial configuration procedure and refer to the next steps at the end of the procedure to get started using the appliance.
If you added this node after initial configuration and previously created a network bond or added a VLAN tag, you must also add those settings on the new node.
