Using Fibre Channel Storage

This chapter provides an overview of Fibre Channel, Fibre Channel configuration examples, and information on Fibre Channel hardware installation and configuration in a Tru64 UNIX or TruCluster Server Version 5.1 configuration.

The information includes an example storageset configuration, how to determine the /dev/disk/dskn value that corresponds to the Fibre Channel storagesets that have been set up as the Tru64 UNIX boot disk, cluster root (/), cluster /usr, cluster /var, cluster member boot, and quorum disks, and how to set up the bootdef_dev console environment variable to facilitate Tru64 UNIX Version 5.1 and TruCluster Server Version 5.1 installation.

______________________ Note _______________________

TruCluster Server Version 5.1 configurations require one or more disks to hold the Tru64 UNIX operating system. The disk(s) are either private disk(s) on the system that will become the first cluster member, or disk(s) on a shared bus that the system can access.

Whether or not you install the base operating system on a shared disk, always shut down the cluster before booting the Tru64 UNIX disk.

All configurations in this chapter are shown with the Memory Channel interconnect, required for TruCluster Server. The illustrations could represent multiple standalone systems by removing the Memory Channel.

This chapter discusses the following topics:

•A procedure for Tru64 UNIX Version 5.1 or TruCluster Server Version 5.1 installation using Fibre Channel disks (Section 6.1).

•Fibre Channel overview (Section 6.2).

•Example cluster configurations using Fibre Channel storage (Section 6.3).

•A brief discussion of zoning and cascaded switches (Section 6.4).
