Verifying Cluster Hardware and Software
Configurations
Before you begin cluster setup, verify the hardware installation, communication
interconnections, and node software configuration for the entire cluster. This
section provides setup information for hardware and software cluster
configurations.
• Each node must include the minimum hardware peripheral components as
described in "Minimum Hardware Requirements" on page 4.
• Each node must have the following software installed:
– Enterprise Linux software (see Table 1)
– The Fibre Channel HBA driver (for a fibre channel cluster)
– Correct version of the
Multi-Path driver (for direct-attached SAS and
iSCSI). For more information, see the documentation that came with
your Dell MD3000/MD3000i storage system.
– Correct version of the Open-iSCSI initiator driver, and the Device
Mapper Mutipath driver, for the Dell EqualLogic iSCSI storage systems.
• The Fibre Channel, or iSCSI Direct-attached SAS, storage system must be
configured with the following:
– A minimum of three LUNs/virtual disks created and assigned to the
cluster storage group (see Table 10)
NOTE: For additional information regarding requirements for assigning virtual disks to
a node in a direct-attached SAS configuration, see the documentation that came with
your Dell MD3000/MD3000i storage system.
