Generally speaking, most boot problems are the result of one of two 
problems: either you are trying to boot from the wrong device or the 
primary boot device is not available. This section suggests remedies for 
those situations.

If you are trying to boot from the wrong device, you must change the boot 
device. Here is a quick way to do that:

1. Reboot:

# /usr/sbin/shutdown -y -g0 -i0

2. From the 

ok

 prompt enter:

ok> printenv

boot-device

The system responds:

boot-device

<disk>

where 

<device> is either the word 

disk, 

indicating the primary 

boot device, or the word 

bootdevice2, 

indicating the alternate 

boot device. (This may be followed by additional device names.) 

To change the boot device, enter the following command:

You should have set up 

bootdevice2 as the alternate boot device 

when you installed disk mirroring.

If the primary boot device is not available, you must change to the 
secondary boot device. 

Changing to the secondary boot device is a matter of entering, from the 

ok

 prompt, the following command:

ok> setenv

boot-device

bootdevice2

You should have set up 

bootdevice2 as the alternate boot device when 

you installed mirroring. 

ok

setenv

boot-device

bootdevice2

ok

setenv
