The system fails to recognize all disk drives

If the system should fail to recognize all disk drives, do the following:

1. Reboot the system by entering the following command:

#/usr/sbin/shutdown -y -g0 -i0

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:

ok

probe-scsi-all

 

 

 

Enterprise 3000

 

 

ok

probe-fcal-all

 

 

 

Enterprise 3500

 

 

 

 

 

 

 

 

 

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-allor probe-fcal-all.

The program responds to the probe as shown below. The specific response, of course, differs depending on the platform.
