Veritas NetBackup™ Flex Scale Administrator's Guide

To add a new node the cluster, complete the following steps:

1. Use any one of the following options to log in using the user account that you created when you configured the cluster:

   • Use a user account with both Appliance Administrator and NetBackup Administrator role, or a user account with only an Appliance administrator role to log in to the NetBackup Flex Scale web interface https://ManagementServerIPorFQDN/webui where ManagementServerIPorFQDN is the public IP address, the FQDN, or the short host name that you specified for the NetBackup Flex Scale management server and API gateway during the cluster configuration, and then in the left pane click Cluster Management > Infrastructure.

   • Use a user account with an Appliance Administrator role to log in to the NetBackup Flex Scale infrastructure management console https://ManagementServerIPorFQDN:14161 where ManagementServerIPorFQDN is the public IP address, the FQDN, or the short host name that you specified for the NetBackup Flex Scale management server and API gateway during the cluster configuration, and then in the left pane click Monitor > Infrastructure.

     Note:

     If you access the NetBackup Flex Scale infrastructure management console by using the short host name from a node, set the DNS settings (name server, domain name, and search domain) or ensure that the entry for mapping the short host name to an IP address exists in the hosts file of the node.

2. On the Nodes tab, click Scan for nodes to discover the nodes that can be added to the cluster.
   

   The nodes connected to the private network of the cluster are discovered and displayed under the Discovered nodes section with details such as the node name, storage capacity, serial number, status, and the data network and the management network of the node.

3. Under the Discovered nodes section, select the nodes that you want to add and click Add nodes to the cluster.

   Note:

   You can only add healthy nodes to the cluster.

   If a node is unhealthy because a vendor package RPM is missing, you can add that node. The vendor package is installed during the add node process.

   The node and storage details of the existing cluster and the projected storage summary after you add the nodes is displayed.

4. Specify whether you want to set the priority for NetBackup backup and recovery jobs or data rebalancing. By default, the priority is set to backup and recovery jobs while data rebalancing runs in the background at a lower priority (option Overall system performance). Click Faster reconfiguration to set the priority to rebalancing data across the cluster. This option increases the speed of node addition operations so that the new node can begin participating in backup and recovery operations faster but may affect the performance of backup and recovery jobs.
5. Enter the following information for the selected nodes:

   • Host name: Name for the node. The node name can contain a maximum of 63 characters, excluding the domain name.

     The serial number of the node is displayed, which helps to identify which node is assigned the specified node name.

     By default, the auto-generated node name based on cluster and domain name is displayed.

   • Data-Network-<device-name>:

     You can specify the IP address and either a fully qualified domain name (FQDN) or a short host name, or you can specify only the IP address for the media server and the MSDP engine.

     The FQDN or the short host name of the media server and the MSDP engine can contain a maximum of 64 characters, including the domain name.

     Note:

     The node name and serial number are displayed so you can identify the nodes and assign a specific IP address to each of the media server and MSDP engine.

     On the Automatic tab, specify a single IP range, multiple IP ranges separated by a comma, comma-separated individual IP addresses, a combination of individual IP addresses and IP ranges separated by a comma, or IP addresses in CIDR format, and then click Add. You are not required to enter the FQDN or the short host name for the media server and the MSDP engine. The FQDN is calculated based on the specified IP addresses.

     Click the Custom tab to specify the IP address and either a fully qualified domain name or a short host name of the media server and the MSDP engine for each node. The media server and the MSDP engine names can contain a maximum of 64 characters, including the domain name.

   • Management Network:

     You can specify both the IP address and an FQDN, or you can specify only the IP address to assign to the management network of the nodes that you want to add.

     The serial number of the node is displayed so you can identify the node and assign a specific IP address to each of the management interfaces of the node.

     On the Automatic tab, specify a single IP range, multiple IP ranges separated by a comma, comma-separated individual IP addresses, a combination of individual IP addresses and IP ranges separated by a comma, or IP addresses in CIDR format to assign to the eth1 management network interface, and then click Add. You are not required to enter the FQDN or the short host name. The FQDN is calculated based on the specified IP addresses.

     Click the Custom tab to specify the IP address and either a fully qualified domain name or a short host name to assign to the eth1 management network interface. If you have already configured the IP address for eth1, the IP address is displayed.

   • IPMI Network: If an IPMI network is configured for the cluster, specify a public IP address to assign to the IPMI interface.

     On the Automatic tab, you can specify a single IP range, multiple IP ranges separated by a comma, comma-separated individual IP addresses, a combination of individual IP addresses and IP ranges separated by a comma, or IP addresses in CIDR format to assign to the IPMI network interface, and then click Add.

   Click the Custom tab to specify a public IP address to assign to the IPMI network interface of each of the selected nodes.

6. Click Add nodes to the cluster.

   The progress of the add node operation is displayed on the Infrastructure page.

7. To monitor the status of each of the tasks, click View details on the Infrastructure page. The ongoing and completed tasks for the add node operation are also displayed in Recent activity.

   Before adding the selected nodes to the cluster, the add node operation synchronizes the patches or add-ons that are installed on the cluster with the nodes. However if the version on the selected nodes is later than the cluster nodes, the add operation cannot proceed. If AutoSupport and Call Home settings are configured for the cluster, these settings are synchronized with the nodes.

   Note:

   If the add node operation fails during rebalancing of data, contact Veritas Support to resolve the issue. Do not reimage the node or perform a factory reset.

   After the node is added, you can view the new node and its details on the Nodes tab. The STIG status of cluster is synchronized with the newly added nodes. If the STIG option is enabled for the cluster, the STIG option is also enabled for the newly added nodes and vice versa. The FIPS option is enabled for the added nodes as this option is enabled with the default factory settings for the Veritas Operating System (VxOS) and for NetBackup MSDP when you create a NetBackup Flex Scale cluster.
