Use either s1 or s2 port configured as a TTY interface with a NULL Modem cable.
Use the s2 serial port on each system configured as a TTY interface with a NULL modem cable.
Use the s1 port on each system configured as a TTY interface with a standard serial modemcable.
Verify with IBM support which native serial ports for the server model can be used for HACM pheartbeats.

During normal cluster processing in a five-node cluster,one of the nodes unexpectedly crashes. A review of the system dump indicates that a DMS timeout has occurred. The cluster is configured to use disk heartbeats as a Point-to-Point network. What should be done to address the problem with this configuration?()
第2题:
A customer has an existing rack environment with 18 x365 and 2 x255 servers. How can the customer monitor and manage the hardware even if the systems are shut down?()
第3题:

第4题:
During a planning session, Company.com expresses concern about the behavior of the nodes When HACMP is installed. Once department is reliant on an older piece of equipment that is critical to operations and must communicate to the database server. Previous network changes indicated that this piece of equipment does not support gratuitous ARP. How can HACMP best incorporate this restriction into the cluster design?()
第5题:
During Company.com planning session,Company.com presents the details of the current Network design. The network design serves four separate company facilities, each on as separate subnet. As part of a disaster recovery plan, the customer is evaluating the use of HACMP. Specifically, the have reviewed IPAT via IP aliasing and are questioning the number of IP subnets required. Given the customer’s current configuration,what is the recommended minimum number of IP subnets that would be required?()
第6题:
Company.com with a newly installed cluster has been checking the logfiles to determine if the cluster has had any recent activity. The non-IP RS232 heartbeat connection seems to be having a difficulty. The serial network goes down,and then a couple of minutes later comes back up again. This pattern is repeated many times in the log. If this system was installed without regard to best practices, what is the most likely problem with the serial network?()
第7题:
An HACMP cluster is planned for two logical partitions on IBM p690 servers. Both partitions have three network interface adapters: two service adapters on a production network connected to an IP switch, and an administration adapter on a stand-alone hub that is connected to the p690 server’s HMC. Non-IP hearbeat paths cannot be configured due to the available hardware in the p690 servers. Given the resources available,what is the best configuration for this cluster?()
第8题:
Company.com wishes to use HACMP on two IBM eServer pSeries servers. During the planning session, it was decided to use the native serial ports s1 or s2 for a non-IP heartbeat network. What should be done to ensure the serial network will function with HACMP heartbeats?()
第9题:
A customer needs both a database and application server to communicate over a network. The new systems will be connected to the same network as the current IBM equipment with known IBM serial numbers. How could a pSeries technical specialist best determine which type of network card is appropriate, without making an additional call to the customer?()
第10题:
During Company.com planning session, the network administrator discusses the requirements of having a persistent MAC address associated with the IP Service address. How can this be accomplished using HACMP?()
