The system fails to recognize all disk drives
4
If the system should fail to recognize all disk drives, do the following:
1. Reboot the system by entering the following command:
The system reboots and displays the 
ok
 prompt:
2. Turn off the system unit.
3. Turn off all external devices starting with the system monitor and 
working toward the device farthest from the system unit.
4. Check all disk drive connections to make sure they are secure.
5. Turn on the power to the system components in the opposite order 
in which you powered them off. Power on the SCSI devices first, 
beginning with the device at the end of the chain and working your 
way toward the system unit. Then power on other devices, again 
working your way toward the system unit. 
Finally, power on the system unit itself and the system monitor. 
When you power on the system unit, the system begins to boot. 
Interrupt the boot by pressing Stop-A.
 
The system displays the 
ok
 
prompt.
6. To verify that the system sees all the disk devices, including any new 
drives, enter one of the following commands:
If you receive a “
This command may hang the system
....” 
message, respond with the following steps:
a. Enter:
n
 (to prevent the probe from continuing).
b. Enter:
setenv
auto-boot?
false
(to prevent a reboot when you do the next command)
c. Enter:
reset-all
(it may take a minute to complete).
Now repeat the 
probe-scsi-all
 or 
probe-fcal-all
.
The program responds to the probe as shown below. The specific 
response, of course, differs depending on the platform.
