Oracle PCA is delivered as an appliance: a complete and controlled system composed of selected hardware and software components.
The PCA software ships with the default baud rate set to 9600 on both the compute and management nodes. A serviceability issue may exist when the default baud rate is changed incorrectly. Unreadable text may be seen on the SP console. The SP console may be non-responsive. You, or an Oracle field engineer, may be unable to troubleshoot and/or interact with the node when needed.
Unreadable text on the SP console is commonly a result of baud rate mismatch and is not normally caused by a fault on the motherboard or service processor.
The default baud rate for the server node components is at three locations:
#1 - ILOM
From the /SP/console, you should see text during the entire boot up sequence, from power on, up to and including the login prompt.
It is especially important at these key stages:
- If directed by Oracle Support, you should be able to enter BIOS Setup via F2 or Ctrl-E
Mgmt and Compute server nodes look similar to this
- If directed by Oracle Support, you should be able to enter LSI BIOS via Ctrl-H or Ctrl-Y
- If directed by Oracle Support, you should be able to stop and/or edit grub
(Shown here to verify OS starts and that you can see any errors if any are logged)
- If directed by Oracle Support, you should be able to login
Mgmt and Compute nodes both will have login prompts similar to this
Examples of serviceability issues
You may not see POST errors, node faults, or any other error conditions.
You may not be able to interact with the node via the keyboard when needed.
Complete unreadable text or unknown characters shown
You never see any readable text. System and LSI BIOS are never shown.
The grub screen is never shown. The SP console is non-responsive to any keystrokes.
Partial unreadable text
Some text is readable whereas other text is not. You may or may not see the system BIOS, LSI BIOS, or grub.
The SP console will start and may respond to ESC (
You may be able to run other SP CLI command, but when SP console starts it will only show unreadable text.
The SP console may be responsive to keystrokes but unreadable text will be shown.
Only one line of readable text is seen followed by blank and/or non-responsive console screen.
The SP console is non-responsive to any keystrokes.
