▼ Run POST With Maximum Testing
1. Access the Oracle ILOM prompt.
See “Access the SP (Oracle ILOM)” on page 15.
2. Set the virtual keyswitch to diag so that POST will run in service mode.
3. Reset the server module so that POST runs.
There are several ways to initiate a reset. The following example shows a reset
using commands that will power cycle the host.
Note – The server module takes about one minute to power off. Type the show
/HOST command to determine when the host has been powered off. The console will
display status=Powered Off.
4. Switch to the host console to view the POST output.
The following example shows abridged POST output.
-> set /SYS/keyswitch_state=diag
Set ‘keyswitch_state' to ‘Diag'
-> stop /SYS
Are you sure you want to stop /SYS (y/n)? y
Stopping /SYS
-> start /SYS
Are you sure you want to start /SYS (y/n)? y
Starting /SYS
-> start /HOST/console
Are you sure you want to start /HOST/console (y/n)? y
Serial console started. To stop, type #.
