Multi-Grid Manager provides different ways to view and monitor your Grids. You can view the overall status of your managed Grids or view individual Grid status through the widgets on your Dashboard. You can also navigate to the Grids tab -> Visualization tab, which provides graphical views of the Grids, and the List tab, which lists the managed Grids.

Visualization Tab

When you navigate to Grids -> Visualization, Multi-Grid Manager displays each Grid, including the Master Grid, as a rectangular tile. The first tile represents the Master Grid, and the remaining tiles represent each Grid, arranged in alphanumeric order. Each tile provides pertinent data points at-a-glance and provides options for editing Grid properties, viewing the node tree, and logging in to an individual Grid. 19282613 shows the typical layout of the Visualization tab.

The Master Grid tile provides the following information:

  • Master Grid name
  • Type of Multi-Grid Master (standalone or HA)
  • The number of Grids managed by the Master Grid
  • The Status icon represents the status of the most critical members in the Master Grid. When all members are running properly, the overall Master Grid status is green. When one of the members has operational problems, the overall Master Grid status is red.
  • The External Storage icon represents the connection availability of the external storage server. When the connection is available, the External Storage icon is in green. When it is disabled or not connected, the status icon is in gray. When there is any operational issues, the External Storage icon is in red.

Each Grid tile provides the following information:

  • Grid name
  • Type of Grid Master (standalone or HA)
  • Number of members, networks and network containers managed by the Grid
  • The status of each protocol running on the Grid
  • The Status icon represents the status of the most critical members in the Grid. When all the members are running properly, the overall Grid status is green. When one of the member has operational problems, the overall Grid status is red. When the Grid has not joined the Master Grid, the status icon is grey.
  • The Sync Status icon indicates the synchronization status between the Grid and Master Grid. It can be one of the following:

Green: The Grid is connected to the Master Grid and the synchronization process is running properly. Yellow: The Grid is connected to the Master Grid, but it has been 300 seconds since the last synchronization.
Red: The Grid is connected to the Master Grid, but 600 seconds have passed since the last synchronization, the connection failed, or the join operation failed between the Master Grid and Grid. You can view the syslog to obtain details.
Black: The Grid has not synchronized with the Master Grid.

  • The connection status of the Grid with the Master Grid. This can be Attached or Detached.
  • Last Sync Time: The date and time the Grid last synchronized with the Master Grid. In addition, you can do the following from each tile:
  • Click the Single Sign On icon to sign in to the Grid. Note that you can automatically sign in to the Grid, only if you have validated your admin account for that Grid. For information about validating your account, see /wiki/spaces/mgmadminguide/pages/911180119 /wiki/spaces/mgmadminguide/pages/911180119.
  • Click the Edit icon to set Grid properties. For more information, see /wiki/spaces/mgmadminguide/pages/911183171
  • Click the Node Tree icon to display the Node Tree for that particular Grid. For more information, see 19282613 19282613

Above the tiles, you can do the following:

  • Click Turn Auto Refresh On to periodically refresh the node tree. This feature is turned off by default. You can click the Refresh icon to update the contents of the node tree.
  • Click the Visualization icon to open a new browser window for the Visualization tab. This allows you to keep a separate browser window open so you can always check the status of your Grids as you perform other tasks. You can click the Refresh icon to refresh the status of the Grids or turn on Auto Refresh.

Viewing the Node Tree

When you click the Node Tree ic on of the Master Grid or a managed Grid, Multi-Grid Manager displays a node tree. In the Master Grid tree, the Multi-Grid Master is the root node at the center and it is connected to the Grid Masters of its managed Grids. Each Grid, in turn, is a subtree with its Grid Master at the center, connected to its members. You can then click a Grid Master to re-center the tree on that node.
The left panel displays the tile of the Grid Master that is at the center of the node tree. For information about the tile, see 19282613. You can click Back to display the Grid tiles. 19282613 displays the typical layout of the node tree, with the Multi-Grid Master at the center of the tree.

Figure 6.3 Node Tree



In the node tree, the shape of the icons indicate the role of the member in the Master Grid or Grid:

  • Square: Grid Master
  • Ellipse: Grid Members
  • Circles: Master Grid Members

The colors of the icons indicate the status of the member:

  • Green: The member is online and functioning properly.
  • Grey: the member has not joined the Grid.
  • Red: The member has operational problems.

The connectors indicate the connection status between the Grid Master and the member.

  • Blue Line: Connects the Multi-Grid Master with online Grid Masters, and Grid Masters with online Grid members
  • Thick White Line: Connects Grid Masters with Grid Master Candidates
  • Dashed Line Connector: Connects Grid Masters with offline Grid members or Grid Master candidates Above the node tree, you can do the following:
  • Click Turn Auto Refresh On to periodically refresh the node tree. This feature is turned off by default. You can click the Refresh icon to update the contents of the node tree.
  • Click the Visualization icon to open a new browser window for the Visualization tab. This allows you to keep a separate browser window open so you can always check the status of your Grids as you perform other tasks. You can click the Refresh icon to refresh the status of the Grids or turn on Auto Refresh.

The node tree includes zooming and panning capabilities to enable quick navigation and selection among multiple nodes. You can also hover your mouse over a node to view node information. It displays the following information for each type of node.
For the Multi-Grid Master:

  • The name of the Multi-Grid Master
  • Indicates if the Multi-Grid Master is a standalone or an HA pair. If it's an HA pair, indicates the status.
  • The number of Grids managed by the Master Grid. For the Multi-Grid Master Candidate:
  • The name of the Multi-Grid Master
  • Indicates if the Multi-Grid Master is a standalone or an HA pair. If it's an HA pair, indicates the status.
  • The number of Grids managed by the Master Grid. For the Grid Master of each Grid:
  • Grid Name
  • Numbers of Members in Grid
  • Status of each protocol running on the Grid
  • Grid Status
  • Synchronization status between the Grid and Master Grid, which can be:

Green: The Grid is connected to the Master Grid and the synchronization process is running properly. Yellow: The Grid is connected to the Master Grid, but it has been 300 seconds since the last synchronization.
Red: The Grid is connected to the Master Grid, but 600 seconds have passed since the last synchronization, the connection failed, or the join operation failed between the Master Grid and Grid. You can view the syslog to obtain details.
Black: The Grid has not synchronized with the Master Grid.

  • Displays the connection status between the Grid and Master Grid. This can be Attaching, Detaching, Attached, Detached, Attach Failed, and Detach Failed.
  • The upgrade status of the Grid.
  • The number of networks and network containers in the Grid
  • The last date and time the Grid synchronized with the Master Grid For a Member:
  • Member name
  • Standalone or HA
  • HA Status if HA pair
  • Status of each protocol running on that member

Listing Grid s

Navigate to Grids -> List tab to view a list of the Grids managed by the Master Grid. This panel displays the following information about each Grid:

  • Grid Name: The name of the Grid.
  • Grid Master Name: The hostname of the Grid Master.
  • Grid Master Address: The VIP or LAN IP address of the Grid Master
  • Status: The status of the Grid.
  • Connection Status: The connection status of the Grid with the Master Grid. This can be Attaching, Attached, Attach Failed, Detaching, Detached, Detach Failed, and Snapshot Failed. For more information, see /wiki/spaces/mgmadminguide/pages/911183089 /wiki/spaces/mgmadminguide/pages/911183089.
  • Service Status: Overall status of the services on the Grid.
  • Last Sync Date/Time: The last date and time the Grid synchronized with the Master Grid.
  • Members: The number of members in the Grid.

  • Comment: Comments that were entered for the Grid.
  • Site: Values that were entered for this pre-defined extensible attribute.
  • Disabled: Indicates if the Grid is disabled.
    Note: When you upgrade, the Grid data (number of members, networks and containers) displays 0 for the first time until the data is synchronized. Grid data displays the actual values after the database synchronization.
    You can click the Add icon to add a Grid to the Master Grid, and you can also select a Grid and do the following:

Removing a Grid

Removing a Grid from a Master Grid has no effect on the Grid's data. It just disables the ability to view and manage the Grid from the Master Grid. In addition, if the Grid was managed in strict delegation mode, this restriction is removed as well.
To remove a Grid from the Master Grid:

  1. From the Grids -> List tab, select the Grid checkbox and click the Delete icon.
  2. Click Yes, when the confirmation dialog appears.
