4.1.3 Identify a Not Connected Device

There are a couple of methods to identify a not connected device:

1. The console error message displayed at boot time. (as previously shown).

2. This console error message displayed when a console disk exerciser attempts to exercise a not connected

device.

3. Using the WWIDMGR command, the console can also display the status of fibre channel devices controlled

by an HSG8x.

P00>>>wwidmgr -show wwid -udid 40 –full

4.2 How to Use a Not Connected Device

4.2.1 Using FFAUTO to Autoboot Not Connected Devices

FFAUTO determines console behavior when the system is trying to autoboot. An autoboot is any boot other than a

manual >>> boot command. FFAUTO can be set to ON or OFF. The default state is OFF where console behavior

is not affected. FFAUTO is stored in non-volatile memory therefore its state persists across system resets and

power cycles.

>>> set FFAUTO ON

In the ON state, console behavior is affected during an autoboot. When the console is trying to autoboot, the

console attempts to boot from each “connected” device listed in the bootdef_dev environment variable (>>> show

botdef_dev). If the console reaches the end of the bootdef_dev list without successfully booting, the console goes

to the beginning of the bootdef_dev list and attempts booting again. Disks that are found in the not connected state

are changed to the connected state, thereby enabling the console to access that device.
