You might need to identify the devices on the system to figure out what are the appropriate devices to boot from.
Before you can safely use the probe commands to find out what devices are attached to the system, you need to do the following:
Change the PROM auto-boot? parameter to false and
Issue the reset-all command to clear system registers
If you run the probe commands without clearing the system registers, the following message is displayed:
ok probe-scsi This command may hang the system if a Stop-A or halt command has been executed. Please type reset-all to reset the system before executing this command. Do you wish to continue? (y/n) n |
Change the PROM auto-boot? parameter to false.
ok setenv auto-boot? false |
Clear the system's registers.
ok reset-all |
Identify the devices on the system.
ok probe-device |
The following example shows how to identify the devices connected to an Ultra10 system.
