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 8.
• Each node must have the following software installed:
– Enterprise Linux software (see Table 2-1).
– 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 storage system.
– Correct version of the Open-iSCSI initiator driver, and the
Device Mapper Multipath driver, for the Dell EqualLogic iSCSI
storage systems.
• The Fibre Channel, iSCSI, or direct-attached SAS storage system must be
configured with 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 storage system.
