OS : CentOS 6.7

iLO 4

• BIOS settings ( default settings )

Set ‘BIOS Serial Console Port’ to COM2
Set ‘BIOS Serial Console Baud Rate’ to 115200

• OS

When ttyS1(ttyS1 is for COM2) is not configured on your OS, you will see nothing when connecting to VSP as below.

Access to an iLO over SSH and enter VSP.

$ ssh 192.168.10.10 -l user </>hpiLO-> VSP Virtual Serial Port Active: COM2 Starting virtual serial port. Press 'ESC (' to return to the CLI Session. *** blank *** </>hpiLO->

Configure ttyS1.

Create a file named “ttyS1.conf” under /etc/init directory.

$ sudo vi /etc/init/ttyS1.conf $ sudo cat /etc/init/ttyS1.conf stop on runlevel [S016] start on runlevel [235] respawn instance /dev/ttyS1 exec /sbin/agetty 115200 ttyS1 vt100

Add ttyS1 in securetty file.

$ sudo tail -1 /etc/securetty ttyS1

enable ttyS1.

$ sudo initctl start ttyS1 ttyS1 (/dev/ttyS1) start/running, process 8406

Access to the VSP over SSH.

In CentOS6, init daemon uses upstart, not Sys V init, so ‘telinit q’ does not work.

You need to create a file under /etc/init directory instead of editing /etc/inittab file.

edit /etc/grub.conf so that you can see boot messages.
