In this eLearning module, we will discuss how to monitor cluster status for the IBM® TS7700 to help to detect problems and verify that tasks have been completed.
If you want to monitor the status for all clusters on your grid, view the TS7700 Grid Summary panel. Moving your cursor over each cluster will provide information about throttling status, raw host throughput, and copy queue.
The image in the bottom right indicates the number of system events. Move your cursor over the image to view a list of the most severe events. Click an event to navigate to the events panel. The image in the bottom left indicates the number of system tasks. Move your cursor over the image to view a list of the most recent tasks. Click a task to navigate to the Tasks panel.
Use the actions menu to modify the grid summary view. Select Cluster Families to modify family names, add families, or assign clusters to families. Select Modify Grid Identification to change the grid nickname or description.
To monitor the status of an individual cluster, click the cluster image to view the cluster summary panel. Displayed in the top right corner of the panel is any attached storage; either tape, or cache expansions. Hover over any part of the image to view detailed information. From the Actions menu, you can change the cluster state, or modify cluster information such as the cluster nickname.
Move your cursor over the larger image of the cluster to view information about capacity and the various cluster components. Use the selector at the bottom to switch between the different clusters. Click the circular arrow to view information about the ports. Hover over an item in the ports view for detailed information about that item.
You can use the status pods at the bottom of the panel to monitor the status of cluster capacity, copy queue and health. If a problem is indicated, mouse over the status pod or event indicator to view additional information.
The library request command, sometimes called the Host Console Request function, is usually initiated from a z/OS host to a composite or distributed library within a TS7700 Grid. You can use this function to request information about the TS7700 or perform operations at an attached library, such as adding management features.
The LI REQ Command window is minimized and docked at the bottom of the management interface frame by default. Click the restore window icon at the bottom right of the browser window to open the LI REQ Command window.
Use LI REQ Command to invoke host library request commands from within the TS7700 Management Interface.
The LI REQ Command window is persistent while your session is active. However, the command output is stored in browser memory and is lost if you log out, close the browser, or refresh the server. To retain command output during long-running commands, save command output frequently.
In this e-Learning module, you learned how to monitor the status of the IBM TS7700. For additional information, see the other topics in IBM Knowledge Center.
