4.3.3 Shared Storage

SCSI can be used for up to four-node clusters; FibreChannel and iSCSI can be used for clusters of

up to 16 nodes.

4.3.3.1 FibreChannel

FibreChannel cards can be used to connect up to 16 nodes to a disk array containing storage.

After installation of the cards and the appropriate driver, the LUNs configured on the storage unit

are presented to the operating system as device files, which can be used to build LVM volume

groups.

NOTE: Multipath capabilities are supported by FibreChannel HBA device drivers and the Linux

Device Mapper. Check with the storage device documentation for details.
