The remaining steps apply only to fabric configurations. In

this release, you cannot boot from storage that is connected

via a Fibre Channel arbitrated loop.

a. Use the wwid manager to show the Fibre Channel environment

variables and determine which units are reachable by the system.

This is the information the console uses, when not in wwidmgr

mode, to find Fibre Channel devices:

P00>>> wwidmgr -show ev

wwid0 133 1 WWID:01000010:6000-1fe1-0000-0d60-0009-8080-0434-002e

wwid1 131 1 WWID:01000010:6000-1fe1-0000-0d60-0009-8080-0434-002f

wwid2 132 1 WWID:01000010:6000-1fe1-0000-0d60-0009-8080-0434-0030

You must set the console to diagnostic mode to use

the wwidmgr command for the following AlphaServer

systems: AS1200, AS4x00, AS8x00, GS60, GS60E, and

GS140. Set the console to diagnostic mode as follows:

P00>>> set mode diag

P00>>>

b. For each wwidn line, record the unit number (131, 132, and 133)

and worldwide name for the storage unit. The unit number is the

first field in the display (after wwidn). The Nn value is the HSG80

port being used to access the storage units (controller B, port 2).

c. Clear the wwidn and Nn environment variables:

P00>>> wwidmgr -clear all

d. Initialize the console:

P00>>> init

e. Use the wwid manager with the -quickset option to set up the

device and port path information for the storage units from where

each system will need to boot. Each system may need to boot from

the base operating system disk. Each system will need to boot

from its member system boot disk. Using the storage units from
