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
5.0A configuration.
The information includes 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 5.0A and
TruCluster Server Version 5.0A installation.
______________________ Note _______________________
TruCluster Server Version 5.0A 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.
This chapter discusses the following topics:
• The procedure for Tru64 UNIX Version 5.0A or TruCluster Server
Version 5.0A 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).
• The steps necessary to install the Fibre Channel hardware, base
operating system, and cluster software using disks accessible over the
Fibre Channel hardware (Section 6.5 through Section 6.10).
• Changing the HSG80 from transparent to multiple-bus failover mode.
