During an HACMP migration,two nodes of a four-node cluster have been migrated. The existing hardware of the remaining two nodes do not meet the pre-requisites of the HACMP level that is being installed. Which of the following is the best method for resolving this issue?()
A two-node cluster is attached via SAN to shared disk. The customer has requested that one of the nodes be moved to another room 300 feet away. However, this distance exceeds the length specified by the RS232 specifications. What solution would resolve the RS232 specification issue with the fewest additional components?()
Company.com has installed HACMP and is configuring a three-node cluster. One of the Applications uses the AIX hostname as a key for authorization to execute on the specific computer. The application vendor was contacted and consented to having multiple copies of the application but required that only one application be active at any one point in time. How can the AIX host name dependency be managed in an HACMP environment.()
An existing cluster has an application node and database node. Changes in the application require both nodes to have access to the other’s data all of the time. Which facility managed by HACMP can be implemented with the least amount of impact?()
Company.com has a two-node HACMP cluster with a single cascading resource group. Node ’A’ is the normal production node, and Node ’B’ is the standby node. One of the first steps in the HACMP test plan is to start the cluster and to verify that al elements for the resource group have been acquired. The administrator who is conducting the HACMP test starts the HACMP daemons on Node ’B’ with the ’smitty clstart" command. The administrator notices that Node ’B’ acquires the elements of the resource group, including a service IP labels,a shared volume group, and an application server that has been started. The expectation was that Node ’B’ would enter the cluster in a standby status, rather than acquiring production resources. What should the administrator do to correct this problem?()
An administrator is planning a two node cluster containing Node1 and Node2 with a single resource groupnamed RG1. RG1 startup policy will be ’Online on Home Node only’. The home node is Node1. If RG1 fails over to Node2 itmust fall back to Node1. Fall back must take place outside of business hours. The agreed time for fall back is20:00. How will this be achieved with minimum action taken by administrator?()
What are three functions of a WebSphere Node Agent?()
During a planning session, it is determined that a three node cluster (Node ’A’, Node ’B’, and Node ’C’) will meet the customer’s application needs. Node ’B’ will be a hot-standby fallover node for both Node ’A’ and Node ’C’ resource groups. A serial network for this cluster will require which connections?()
