Rollup servers

Rollup reporting combines capacity and status information from multiple instances of IBM Spectrum Control for monitoring and reporting. In rollup mode, secondary rollup servers collect information from managed resources and roll that data up to primary rollup servers.

Rollup capability requires two types of servers: a primary rollup server running IBM Spectrum Control, which collects capacity and status information from one or more secondary rollup servers. Secondary rollup servers communicate with the primary rollup server during server probes.

The primary rollup server collects capacity and status information about storage resources that are managed by the secondary rollup servers. This primary/secondary rollup server configuration is called rollup mode. When you enable rollup mode on the primary rollup server, you can see capacity and status information in the rollup resource pages for the storage systems, servers, hypervisors, switches, and fabrics that are monitored by your rollup servers.

You can also configure a primary rollup server as a secondary rollup server to other primary servers. This allows you to create a comprehensive rollup reporting structure across your enterprise.

Note: If you configure a primary rollup server as a secondary rollup server to another primary server, the data collected by that primary server is not rolled up to the higher primary server. Primary rollup servers only collect and display data from their immediate secondary rollup servers. For example, if you configure primary rollup server 2 as a secondary to primary rollup server 1, the data that is rolled up to primary rollup server 2 from its secondary servers is not collected by primary rollup server 1. Primary rollup server 1 only collects capacity and status information about primary rollup server 2, not the secondary servers monitored by primary rollup server 2.

Note: After you upgrade a primary rollup server you must run probes of the secondary rollup servers that were added to the primary server prior to the upgrade. Use the Start Probe action to run probes of the secondary rollup servers. Wait for the first probe (manual or scheduled) to complete, before you work with a new function.

Managing secondary rollup servers

After you add a secondary rollup server on the Settings > Rollup Server Connections page, you can view information about the server and perform actions on it. You must have IBM Spectrum Control Administrator role authorization to add, remove, and manage secondary rollup servers on this page.

Information about secondary rollup servers

IBM Spectrum Control provides the following information about the secondary rollup servers on the Rollup Server Connections page:

Managed resources: The number of block storage systems, servers, switches, fabrics, and hypervisors that the secondary rollup server is managing. You can view information about these resources on the rollup resource list pages for the resources, such as the Switches (Rollup) page. NPV switches are not included in this number on either the primary rollup or secondary rollup Switches (Rollup) resource list pages.
Data collection: The status of the last probe of the secondary rollup server, and the time of the next probe of the server. Hourly probes are automatically scheduled when a secondary rollup server is added to a primary rollup server.

Actions

You can perform the following actions on the secondary rollup server. Unless otherwise noted, you must have Administrator role authority to perform these actions.

Open logs: Opens the probe logs window for the secondary rollup server in a separate browser window. Any IBM Spectrum Control user role can perform this action.
Start probe: Starts a probe of the secondary rollup server. If a probe is already running for the server, you must wait until the current probe completes before starting a new probe.
Remove server: Removes the secondary rollup server from the Rollup Server Connections page and the Servers (Rollup) list. Also removes any associated resources that are managed by the secondary rollup server. For example, if a secondary rollup server is the managing instance for a switch and the secondary server is removed from the primary rollup server, the switch will no longer display on the Switches (Rollup) resource list page.
Note: Removing a secondary rollup server on the Rollup Server Connections page does not remove that server from the non-rollup Servers page. If the server has been added by using the Add Server dialog on the non-rollup Servers page, IBM Spectrum Control will continue to manage that server unless you remove it from the Servers page.
Modify connection: Allows you to change the host name, user name, password, and port of the secondary rollup server.

Rollup mode

Rollup mode is a special view of your enterprise and is enabled by configuring your IBM Spectrum Control servers to communicate and gather data through server probes. Rollup mode requires a primary rollup server configured to collect capacity and status information from one or more secondary rollup servers. Once you have configured a primary rollup server with at least one secondary rollup server, you can go to the rollup icon Rollup mode icon disabled in the menu bar to enter rollup mode. The rollup icon does not display until you have configured at least one secondary rollup server for the primary rollup (local) server. You might have to refresh your browser window to see the rollup icon after you add the first secondary rollup server for the primary rollup server you are configuring.

Entering rollup mode

To view rollup capacity and status information from your IBM Spectrum Control servers, you must enter rollup mode.

On the Rollup Server Connections page, add at least one secondary rollup server. Secondary rollup servers must have IBM Spectrum Control installed and running.
Move the mouse pointer over the rollup icon in the menu bar and select Enter rollup mode.

You will see the following changes in the menu bar:

The color of the rollup icon changes: .
The lower edge of the menu bar changes to orange.
The menu bar options change to Storage, Servers, Network, Rollup Server Connections.

Using rollup mode

Rollup mode provides lists of resources that are managed by secondary rollup servers. For example, you can see a list of all the network switches that are managed by a primary rollup server and its associated secondary rollup servers. These resource list pages are similar to the pages you work with when not in rollup mode. However, in some cases rollup mode provides different data columns and different actions that you can take on the rollup storage devices.

View rollup information

In the rollup menu bar, select the type of storage device you want to view information about. For example, Servers.
Select one of the available menu options. The Servers menu bar item has two options: Servers and Hypervisors.
On the resource list page, you can see the data about that resource type that has been collected from the primary and secondary rollup servers.
Rollup resource lists function similar to non-rollup pages: you can add and reorder data columns, right-click items in the resource list to perform actions on them, and other familiar functions. You can also use Ctrl-click to select multiple list items.

Actions

You can perform actions on items in the resource lists by right-clicking them or by selecting one or more list items and clicking Actions.

View properties: View the properties of the selected item in the resource list. This action is not available for multiple selections at the same time.
Export: Export the data for one or more list items. You can specify PDF, CSV, or HTML output.
