Verifying Cluster Network Communications
To ensure proper cluster operations, the cluster nodes must be able to communicate with each other through the private network (cluster
interconnect). This communication involves the exchange of heartbeat messages, whereby the two cluster nodes inquire about each other's
status, or "health," and acknowledge each inquiry.
To verify network communications between the cluster nodes:
1. Open a command prompt on each cluster node.
2. At the prompt, type:
ipconfig /all
3. Press .
All known IP addresses for each local server appear on the screen.
4. Issue the ping command from each remote system.
Ensure that each local server responds to the ping command.
Installing the Fibre Channel HBAs
For dual HBA configurations, Dell recommends installing Fibre Channel HBAs on separate PCI buses. Placing the adapters on separate buses
improves availability and performance.
See the Platform Guide for more information about your system's PCI bus configuration and supported HBAs.
Installing the Fibre Channel HBA Drivers
See the EMC documentation that is included with your HBA kit for more information.
See the Emulex support website located at www.emulex.com or the Dell Support website at support.dell.com for information about
installing and configuring Emulex HBAs and EMC approved drivers.
See the QLogic support website at www.qlogic.com for information about installing and configuring QLogic HBAs and EMC approved drivers.
See the Platform Guide for information about supported HBA controllers and drivers.
Installing and Configuring the Shared Storage System
See " Storage System " for a list of supported Dell | EMC storage systems.
To install and configure the Dell | EMC storage system in your cluster:
1. Update the core software on your storage system with the EMC Access Logix™ software (optional) and install any additional software
options, including EMC SnapView™, EMC MirrorView™, and SAN Copy™. See your Navisphere® documentation for more information.
2. Install the EMC Navisphere Agent and EMC PowerPath® software on each cluster nodes.
