Managing HP Serviceguard Extension for SAP for Linux, December 2013

3 SAP cluster administration
In SGeSAP environments, SAP application instances are no longer considered to run on dedicated
(physical) servers. They are wrapped up inside one or more Serviceguard packages and packages
can be moved to any of the hosts that are inside of the Serviceguard cluster. The Serviceguard
packages provide a server virtualization layer. The virtualization is transparent in most aspects,
but in some areas special considerations apply. This affects the way a system gets administered.
This chapter discusses the following topics:
• Performing cluster administration in the System Management Homepage (SMH)
• Performing SAP administration with SAP's startup framework
• Change management activities
3.1 Performing cluster administration on the System Management
Homepage (SMH)
SGeSAP packages can be administered using HP SMH. After login to SMH, click the Serviceguard
icon to access the Serviceguard Manager pages. Choose a cluster that has SGeSAP installed. In
the Map and Large Scale Grid views, from the View window on the right side of a page, move
cursor over a package icon to display the package information pop-up window. Each SGeSAP
package is identified as such in the package pop-up information under the Toolkits heading. In
the Table view, the toolkit is listed in the Type column of the Package Status table.
Figure 9 Pop-up information for SGeSAP toolkit package
To run, halt, move or enable maintenance for an SGeSAP toolkit package:
• From the View window on the right side of the Serviceguard Manager Main page, right click
on a package icon to bring up the Operations menu, then click Run Package, Halt Package,
or Enable Package Maintenance to bring up the screen(s) that will allow you to perform each
of these operations.
• You can also perform administrative tasks by clicking the Packages tab on the Serviceguard
Manager Main page to bring up the Packages screen. Select the package you want to perform
administrative tasks, and then click Administration in the menu bar to display a drop down
menu of administrative tasks. Click the task you want to perform to bring up the screen(s)
associated with performing that task.
