Figure 2 shows screen for adding application controller scripts.

So there will be an application controller start,stop script, and also monitor script to monitor application in a cluster. Run the smit hacmp command at the command prompt. Monitor script is not yet added so it wont display. This section demonstrates hqcmp to add application controller and monitor scripts are added to PowerHA cluster.

If there is wrong path in script only on one node, resource group will try to come ONLINE on that particular node but after completing 3 restart count it will fall over to next node as per restart count set in Figure 3if next node has everything correct in application then cluster will be stable and resource group will come online on that node.

View image at full size. So manual intervention is required as per hacmp.

Second field is to add start script and third field is to add stop script. Proposed the implementation of optimisations to limit the cost of Infras while guaranteeing the level of service requested by different business networks.

There are chances, that due to wrong input in resource or applications, cluster might not bacmp to stable state and resource group might go to error state. An application will nacmp added to resource group under a volume group and a file system will be created on it.

This article can help users hacml get recovery from cluster failure due to failure in a resource or application caused by the wrong input. An application controller name is user defined. This will allow cluster to get stable on that nodes and if script is correct resource group will come online on that node.

Cluster is created from SiteANode1 and changes are propagate on all nodes in cluster through verify and sync feature. This article describes how to recover from application failure in a cluster using four nodes stretched cluster.

This will ask for which resource group to be selected to add applications and file system to it. Subscribe me to comment notifications. The first field is mandatory as it ask about the controller name. Comments Sign in or register to add and subscribe to comments. Application under that Resource group is also not started. This application is a resource under resource group RG1.

PowerHA provides feature that allows a cluster to come into stable state and resource active as per the policy after correcting wrong input without stopping the cluster services. Similarly more than two nodes cluster can be created along with Site separation based on repository disk.

Implemented, prepared and hosted technical capacity committees with the SCS cluster aiming to cover the perimeter of shared technical infrastructures offered by CAPS. If a script is failed because of the wrong input to PowerHA, the Cluster Manager will report failure in hacmp. To understand this with application failure, we will change the path for application in start scripts on all the nodes.

If resource group on all the nodes go to ERROR state that means wrong input is there on all the nodes. Established a monthly capacity plan. Figure 1 shows a four-node stretched cluster setup. An application will not be able to stabilize with that wrong path in above mentioned script.

This article explains about configuring base PowerHA cluster with two nodes.

The following section describes how to enter the parameters shown in Figure 3, while creating an application monitor. Therefore, in this case application app1 is failed because of the wrong path mentioned for an application in the start script.

So, in that case resource group has to be brought ONLINE manually after rectifying the wrong input on all nodes, where as if resource group is in ERROR state on one node, recovering from cluster script failure can get it to proper state after correcting wrong input.

Customer can get a cluster to a stable state and a resource group to an accessible state after rectifying the wrong input to their resources.
