Once the LAN IP, LAN Netmask, LAN Gateway, Backplane IP of this node, and Backplane IP of first node in system (which will be the same as Backplane IP of this node on the first node). See below for an example of the first node’s IP configuration. © ​Scale Computing 2019 Version 3.0: 02/2019 | 18

when it either returns to the command line or the output says Entering forwarding state. The configuration process generally takes 3-5 minutes. Common Configuration Troubleshooting Here are some common troubleshooting steps for node configuration issues. ● Verify the node IPs were typed correctly. ● Verify the chosen LAN and Backplane IP for the node configuration are not already in use elsewhere on the network. ● The LAN and Backplane IPs must be on separate networks. The Backplane IP cannot be a publicly routable IP and cannot be in the assigned LAN IP network. You can use the following commands to re-initialize and/or bypass some network verification if needed for a test environment. WARNING ScaleCare Support advises against bypassing the built-in network checks unless this is for a test or lab environment and/or ScaleCare Support has specifically advised bypassing the checks as part of a troubleshooting process. Use of the bypass command outside of these instances has the potential to lead to networking issues within the initialized HC3 nodes and system that may require ScaleCare Support intervention and/or a system wipe and reset. 1. If the node initialization failed for any reason use this command to re-configure the node: REINITIALIZE=yes sudo scnodeinit 2. If a LAN gateway is not accessible or not responding to ICMP requests, use this command: BYPASS_NETWORK_CHECK=yes sudo scnodeinit 3. As used here, the options to re-configure a node and bypass LAN network checks can be combined: BYPASS_NETWORK_CHECK=yes REINITIALIZE=yes sudo scnodeinit © ​Scale Computing 2019 Version 3.0: 02/2019 | 19

Initialize the System All installations should be scheduled at least 24 hours in advance. The ScaleCare engineer assisting you will provide the necessary credentials during the scheduled installation time. NOTE The commands provided below are applicable to a single node or multiple node installation. Choose the proper option for your configuration. All system initialization is done from the command line using a monitor and keyboard.​ Systems are configured in a top-to-bottom configuration, with the top node in the rack being the designated 'first' node. The 'first node' classification has no bearing on system operations outside of the installation configuration. 1. Hook the monitor and keyboard to the top node in the system. Log in to the node using the provided credentials. a. If you are utilizing the ​SNS configuration​ run the command to initialize the single node. sudo singleNodeCluster=1 scclusterinit b. If you are utilizing the ​cluster configuration​, this command will initialize a system comprised of all the previously configured nodes. sudo scclusterinit 2. You may be prompted for a password. Use the same password as the node login. 3. Configured nodes will be listed on the screen. Verify all nodes that were configured are displayed on the list for system initialization, as seen below. If utilizing the SNS configuration only the single node will be shown. 4. When all nodes are shown follow the prompt and press ​CTRL+c​ to proceed. 5. Enter ​yes​ to complete the system initialization as seen in the example below. 6. It will take approximately 15-20 minutes for the nodes to initialize in a cluster configuration. It will take approximately 10-15 minutes for a node to initialize in a SNS. Once complete the HC3 web interface will be accessible using the configured LAN IP of the node(s). 7. See the applicable User Guide for your software version for information on first-time system configuration if needed. © ​Scale Computing 2019 Version 3.0: 02/2019 | 20
