Verifying Cluster Hardware
and Software Configurations
This section provides setup information for hardware and software
cluster configurations.
Before setting up the cluster, verify the hardware installation, communication
interconnections, and node software configuration for the entire cluster.
• Each node must include the minimum hardware peripheral components as
described in "Minimum Hardware Requirements" on page 9.
• Each node must have the following software installed:
– Enterprise Linux
®
software (see Table 2-1, Table 2-2, or Table 2-3).
– The Fibre Channel host bus adapter (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™ PowerVault™ 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, iSCSI, or 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 4-1)
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 PowerVault MD3000/MD3000i storage system.
