When you configure a failover package, you specify which active node will be the primary node where the package will start, and one or more other nodes, called adoptive nodesthat can also run the package. Serviceguard hides the details of which server an application is actually running on at any given time, which means it can move applications between servers on the fly. The amount of required shared storage will depend on the application requirement.

Verification completed with no errors found. It usually is configured to run on several nodes in the cluster, and runs on one at a time.

Check the syslog files on all nodes in the cluster to verify that no warnings occurred during startup. Most Serviceguard packages are failover packages. I will try to make this cluste.

A package groups application services individual HP-UX processes together.

In the event that one component fails, the redundant component takes over. We will use three of them. Similarly, node 2 is shown with exclusive access to the bottom two disks solid lineand node 1 is shown as connected without access to the bottom disks dotted line. For a significant portion of installations, a higher setting is more appropriate.

However, there were nsswitch. You can halt a package using Serviceguard Manager or on the Serviceguard command line. In order to remove all single points lcuster failure from the cluster, you should provide as many separate power circuits as needed to prevent a single point of failure of your nodes, disks and disk mirrors.

This tutorial is only applicable for those who already know the basic concept and just want to learn the basic configuration steps. Complete book in PDF.

Note that the network hardware is cabled to provide redundant LAN interfaces on each node. In addition, a total of four data buses are shown for the disks that are servicegjard to node 1 and node 2.

Check the output carefully. Once the cluster is up and running, we can create a package to run in it. Sorry, your blog cannot share posts by email. Email required Address never made public. Failed to gather configuration information.

Most Serviceguard packages are failover packages. You can do this either in Serviceguard Manager or on the Serviceguard command line.

For this example, connect two NICs on each server to the public Ethernet network, connect the heartbeat cable through a point to point cable. I am not going to discuss any servicegard concept like why someone will use a cluster or what actually a single point of failure is etc etc.

Once the cluster configuration file is edited, you need to use the cmcheckconf command to check the file for errors:. Start the cluster from any node in the cluster: Any host system running in a Serviceguard cluster is called an active node.

Use the cmapplyconf command to apply the configuration. This VG will be used as lock VG: You can get personalized Cluser training by Donald Burleson, right at your shop! Create the group file for the volume group: Serviceguaed the file has been verified as containing no errors, the cmapplyconf command is used to create and distribute the cluster binary file:. If it fails on one active node, that node halts. For example, change the ClusterName and adjust the heartbeat interval and node timeout to prevent unexpected failovers due to GCM traffic.

You are commenting using your WordPress. Deactivate the VG on node01, export the VG information to a map file and transfer the file to the 2nd node node02 here using the following comands:.
