Following a successful cluster fallover, clstat returns no status, the snmpinfo command hangs. All cluster resources appear to be active. What should be done to resolve this problem?
2.
Which of the following must be running on a node for the clstat utility to work properly?
3.
The customer has implemented an SNMP based network monitoring tool and wishes to monitor changes in the cluster. The general status of the cluster is gathered via SNMP but the polling time to retrieve the status is too slow for immediate reaction to serious issues. There is a technical reason why the polling time cannot be changed. How can HACMP report changes in its status on a more timely basis?
4.
During the process of fallover testing, a client/server database needs to be tested. On the AIX Server, start/stop/cleanup scripts and server application functionality have been tested. Before moving onto the next step of fallover testing, what action must be completed?
5.
As part of fallover testing of a corporate database server, client application connectivity must be verified. Which of the following would best verify the application functionality?
6.
A two-node cluster provides NFS exports to a variety of UNIX clients. During fallover testing, it is determined that some clients are unable to mount the exported filesystems after fallover, and before node reintegration. It is verified that the filesystems belong to a resource group and are correct in /usr/es/sbin/cluster/etc/exports. Which of the following may provide a possible solution to this problem?
7.
Following an unsuccessful cluster fallover test, it is determined that the nfsrg1 resource group was the problem causing the cluster to run the config_too_long event. The nfsrg1 resource group contains 10 nfs filesystems that are cross-mounted to the other cluster node. Without modifying the time until warning parameters, what can be done to enhance NFS fallover performance?
8.
During cluster fallover testing, the administrator determines that additional work is required to stop existing test applications on the standby node, prior to starting the production applications on the surviving node. To manage this type of requirement, which step should be performed first?
9.
While executing a Cluster Test Plan, the administrators realize that they will need to email the operations and network on-call staff in the event of a network outage. What can be done to alert the on-call staff of network failures?
10.
A customer recently updated the programs used in an HACMP pre-event. The procedure involved coping the new code over the old code in the appropriate directory on one of the nodes as indicated by the HACMP event entry. The cluster was synchronized. During a fallover test, the backup system did not behave as expected. What is the most likely problem?
