Managing Nodes

In the S1 system, storage is provided through the use of storage node servers. Everything is connected to the system through these node servers. The Node section provides information about the status of the nodes. It allows you to connect to a specific node, edit the names of the nodes, and perform giveback and takeover actions. Additionally, you can utilize the support tunnel for encrypted communication with the system and use command line utilities to test connectivity with the node servers.
To access the Nodes section, select Inventory adminadmin > Nodes adminadmin. A table listing all of the available server nodes displays. To expand or filter the table by columns, select following controllers.

  • Sensors: To display system status from the server nodes' sensors.
  • Gateway: To display information about server nodes gateway.
  • Vols: To display information about the volumes in each of the nodes.
  • IP: To display the IP nodes of each of the nodes.
  • Sed: To display information about self encrypted drive.

Server node Id

To display a list of server node IDs, select Sessions from the top menu control. A table listing the names of the nodes and their related IDs displays. To filter the table for an ID of a particular server node select the node in the Node drop-down.

Connect to a node

To connect to a particular node, select Connect from the top menu control. Select the node in the Node drop-down and Submit. This changes the current management connection to the selected node.

Rename a node server

To rename a node, select Edit from the top control menu. Select the node in the Node drop-down list and enter a name in the Newname field. Select Submit.

Takeover

This operation changes the high availability state of the nodes. It allows one server node to take over all the volumes from the other server node. This changes the state of the server node that takes over the volumes to all and the other server node to none. To perform this operation, select Takeover from the top menu controllers. Select the node server in the Node drop-down and Submit. To force the take over operation check the Force checkbox before submitting.

Giveback

This operation changes the high availability state of the nodes. This operation may performed in the case where one server node took all volumes from the other server node. In such a case the server node may giveback the volumes to the other server node. To perform this operation, select Giveback from the top menu controller and Submit.

Encrypting communication through supportSupport tunnel

SupportThe support tunnel refers to a mechanism that allows remoteStorONE support to remotely access and support to a network device oryour system. It enables a secure connection to your StorONE system using secure protocolsa suchsecure as SSHshell (SecureSSH) Shell)that oris VPNonly (Virtualaccessible Privateby Network).
internal StorONE personnel.

To access the Tunnel section, select Inventory adminadmin > Nodes adminadmin = Support adminadmin > Tunnel adminadmin . A table listing the support status of the tunnel is displayed. If the support tunnel of a node is enabled, then the encryptiontunnel key appears in the Support Tunnel Status column, inside the parenthesis. You can provide this tunnel key to StorONE support to allow them to access and troubleshoot your system.

Disabling a support tunnel

To disable a support tunnel for a node, select Disable from the top menu control. Select a node in the Node drop-down list and Submit.

Enabling a support tunnel

To enable a support tunnel for a node, select Enable from the top menu control. Select a node in the Node drop-down list and Submit.

Using Utilities to test connectivity

To test and measure network connectivity with the server, select Utils adminadmin.

  • Node: Select the server node to test connectivity.
  • Utility: To run commands on the selected server node. Options for the commands are:
  • Args: Enter the IP address of the node. The IP may be preceded by command modifiers. For example, for a node in IP 192.168.60.20 and command ping, you may enter -c 3 192.168.60.20 to limit the results to three pings.
  • Timeout Seconds: To limit the operation of each of the commands. If not specified, then each command has a timeframe of ten seconds to run.
