This article can help users to get recovery from cluster failure due to failure in a resource or application caused hhacmp the wrong input. This section demonstrates how to add application controller and monitor scripts are added to PowerHA cluster. The first field is mandatory as it ask about the controller name.

An application will not be able to stabilize with that wrong path in above mentioned script. Monitor script can be added after creating application controller or before application controller also. In this cluster, one network and three resource groups are created. Therefore, in this case application app1 is failed because of the wrong path mentioned for an application in the start script. Comments Sign in or register to add and subscribe to comments. If a script is failed because of the wrong input to PowerHA, the Cluster Manager will report failure in hacmp.

Subscribe haacmp to comment notifications. Deliverables for each business are described in the table below. 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.

Monitor script is not yet added so it wont display. Sign in or register to add and subscribe to comments. X and Toad o Approved technical solutions proposed by suppliers. Application under that Resource group is also not started.


An application will be added to resource group under a volume group and a file system will be created on it. So there will be an application controller start,stop script, and also monitor script to monitor hacnp in a cluster.

AU54 – HACMP System Administration I – Planning and Implementation – 资料 – twt企业IT交流平台

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. If resource group on all the nodes go to ERROR state that means wrong input is there on all the nodes. To understand this with application failure, we will change the path for application in start scripts on all the nodes. The following cltopinfo utility output shows a basic cluster information.

Therefore, a cluster recovery from script failure will get cluster to proper state and EVENT will be completed in hacmp.

HACMP System Administration III: Problem Determination and Recovery

View image at full size. The following section describes how to enter the qu shown in Figure 3, while creating an application monitor. RG1 is nonconcurrent resource group and other 2 resource groups are concurrent groups. Proposed the implementation of optimisations to limit the cost of Infras while guaranteeing the level of service requested by different business networks. Run the smit hacmp command at the command prompt. If there is wrong path in script only on one node, resource group will try to come ONLINE on nacmp particular hacmmp 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.


Recovering from a resource failure in IBM PowerHA cluster

This article explains about configuring base PowerHA cluster with two nodes. This will ask for which resource group to be selected to add applications and file system to it. Nacmp, applications and file system will be added to resource group RG1. This article describes how to recover from application failure in a cluster using four nodes stretched cluster.

Figure 2 shows screen for adding application controller scripts. This will allow cluster to get stable on that nodes and if script hcamp correct resource group will come online on that node. An application controller name is user defined. Site based cluster can be stretched cluster or linked cluster, stretched cluster is at same location where as linked cluster is configured where data centers are at different geographical locations.
