Registering Virtuozzo or Plesk Nodes
When a Virtuozzo or Plesk node is registered in Parallels Business Automation - Standard, this means that a connection is established with this node and a certain data exchange is possible between a node and the Parallels Business Automation - Standard database. To make a node registration possible, a node must be up and running and available over a network.
A registered node may become unavailable because of outages on a node itself or network connection loss. When a registered node becomes available, the connection is re-established automatically.
It is possible to break the connection to a node (i.e., unregister it) by one click. It this case the connection to a node will remain established, but events on a node will stop synchronizing with Parallels Business Automation - Standard database and thus, creation of new Containers or Plesk Clients/Domains from Parallels Business Automation - Standard web-based interface will become impossible.
Registered Virtuozzo nodes allow a wider range of operations: manage applications installed, operate Containers (create new, start, stop, delete, etc.), manage Containers backups, manage trial Containers creation settings, adjust traffic shaping and allow name-based Containers creation. Registered Plesk nodes allow viewing and adding new Plesk Clients or Domains and setting permissions for trial Plesk Domains creation.
To view the list of Virtuozzo or Plesk nodes connected to Parallels Business Automation - Standard, click Nodes either on Virtuozzo Manager or Plesk Manager submenu under the Service Director.
The list of nodes displays the following:
- ID - Numerical identifier, assigned to the Hardware Node.
- Shortname - Hardware node friendly name.
- IP Address - Current IP address assigned to a node.
- The number of subscriptions on a Hardware Node:
- For Virtuozzo Nodes - the Accts column shows the number of Containers on a node. If the number of Containers is limited, then the current number and the maximal allowed number of Containers will be shown, e.g., "40 of 100" means that a node runs 40 Containers of the 100 allowed.
- For Plesk Nodes - Domains and Clients columns show the number of Plesk domains existing on a Node.
- New Accts - Whether it is allowed to create more subscriptions on a Node. Green tick indicates that yes, red cross - that not.
- Platform - the software installed on a node.
- Version:
- For Virtuozzo nodes the full version of the VzAgent running on a node.
- For Plesk nodes - the OS installed and the full version of Plesk Server Administrator installed on a node.
- Reg. Status - The current Hardware Node status in respect to its manageability via your Control Center web-based interface:
- Registered - the connection with a Hardware Node was established successfully, a Hardware Node is fully manageable;
- Conflicts - the data found on a node does not correspond to the data existing in Parallels Business Automation - Standard database or some other problems occurred during registration. To resolve the data conflicts, you can use the special tool provided in Parallels Business Automation - Standard - Conflicts Resolver.
- Unregistered - the connection with a Hardware Node is not established but a Hardware Node configuration is stored in the Parallels Business Automation - Standard database. Such a Hardware Node cannot be managed from Parallels Business Automation - Standard web-based interface.
- Availability - Current status of a node in respect to establishing connection to it. Unavailable node usually means some kind of hardware or network problems on a node.
- Owner - An Account which owns a Hardware Node, if any.
To register a new node:
- Click the New Hardware Node button on a nodes list screen.
- Set the option button to one of the following to select the Hardware Node platform:
- Hardware Node with Parallels Virtuozzo Containers installed if you are registering a Hardware Node with Parallels Virtuozzo Containers installed. Since the connection to a Virtuozzo Hardware Node is established using the special Virtuozzo management interface (called vzagent) running inside the special Container (called the service Container) on a Hardware Node, please enter the IP address of this service Container into the Service Virtuozzo Container IP address field and the password of the service Container administrator (the special vzagent0 user) into the Service Virtuozzo ;Container Administrator password field.
Important: Before registering a Virtuozzo node, please make sure that both Ping and SSH connection is allowed from your Management node to service Container on a Virtuozzo node you want to register.
- Hardware Node with Plesk7 installed if you are registering the Hardware Node that runs Plesk. Type the Plesk Hardware Node IP address into the IP Address field. And into the Plesk administrator password field, please enter the Plesk node administrative user password.
Note: If you are registering the Plesk Hardware Node with Plesk domains or Plesk Clients running, then Parallels Business Automation - Standard will automatically drag these data into Parallels Business Automation - Standard and you will be able to assign a client or a domain to one of the Parallels Business Automation - Standard accounts and create a full-featured Parallels Business Automation - Standard subscription with ability of upgrades, subscription renewals, online payments, etc.
- Click the Next button. Fill the form (or check the contents of pre-filled fields):
Note: For Plesk and Virtuozzo Hardware Nodes, the form fields will be pre-filled with the Hardware Node parameters (OS installed, CPU parameters, memory, etc.) detected. For non-Virtuozzo Hardware Node, you will need to specify all the parameters manually (mandatory fields are marked with asterisks):
- Hardware node name - Hardware Node alphanumeric identifier, any combination of letters and (or) digits you consider convenient to refer to a Hardware Node within your Parallels Business Automation - Standard system. A Hardware Node short name will be used both in the lists of Parallels Business Automation - Standard objects (Hardware Nodes and Containers) and other Hardware Nodes related operations (for example, assigning IP Pool to a Hardware Node). This field should already contain the Hardware Node default name.
- Hostname - Hardware Node hostname. This field should already contain default hostname like hardware_node_name.default_domain; Default value is output of the hostname command. In case of problems, please contact the person who performed your Parallels Business Automation - Standard installation;
- IP Address - The current IP address of a Hardware Node.
Important: The IP address that you are registering the Plesk Hardware Node in Parallels Business Automation - Standard MUST BE SHARED IP. This is necessary for successful resolving of data conflicts between the Plesk node and HSPcomplete database.
- Owner - Dedicated account. A Hardware Node can be either not assigned to any account (set the option button to Not assigned) or it can be assigned to Reseller (set the option button to Assigned to account selected below, click the Select button and select the account from the popup window). This may be done both during registration or later;
- Subscription. You can assign a Hardware Node to one of existing subscriptions or create a new subscription. Set the option button to one of the variants and click the Select button;
- OS - Operating System installed on the Hardware Node.
- OS Release - Corresponds to the installed distribution release number
- Form factor - Hardware Node size in Units (U). May be entered for better manageability if you are going to associate Hardware Nodes logical groping with actual arrangement of hardware boxes (by material racks).
- Architecture - System architecture, CPU Family and type.
- Number of CPUs - Number of CPUs. For licensing purposes.
- CPU speed - For the purpose of licensing speed is measured in MHz of CPU clock.
- Installed Memory - Amount of memory available for Parallels Business Automation - Standard.
- Disk space. The disk space available at a Hardware Node;
- Comment. Any relevant comments can be typed here.
- Click the Save button.
Repeat the steps described above to register more Nodes.
