Serial Console not starting after reimage 10.1 on HW appliance

Products

• CA API Gateway

Issue/Introduction

After reimage physical appliance GW cluster from 9.4 to 10.1, we noticed that ILOM cannot start serial console (it remains hanging):

The  situation is the same on all upgraded appliance, maybe some upgrade has to be applied on ILOM software?

The connection to the appliance via ILOM browser interface works fine

but the one via serial port seems not starting, even if we try to connect plugged with personal workstation on serial port.

Already done "reset /SP", but nothing has changed.

 

Environment

Release : 10.x

Resolution

With gateway 10,x the serial console is not enabled by default on the Centos OS.

To enable it you can run the following steps in the ssh connection or ilom console .

How to Enable Serial Console Output in CentOS:

• open up our text editor: nano /etc/sysconfig/grub.
• Find the line labeled GRUB_CMDLINE_LINUX and add console=ttyS0 to the end (this assumes your serial port is ttyS0). ...
  Save the file and exit.
• Run stty -F /dev/ttyS0 speed 9600.
• Then grub2-mkconfig -o /boot/grub2/grub.cfg.
• Finally systemctl start getty@ttyS0.
