ssh console access

iLO

  • To access a text console through the ssh iLO interface, use the remcons command.

iLO 2

  • With iLO 2, remcons is not available; you may use the Virtual Serial Port (VSP) to access a text console.
  • To access the VSP, login to iLO 2 via ssh and type vsp.
  • The default Virtual Serial Port is COM 2; IRQ3; IO: 2F8H-2FFh (at least on an HP ProLiant DL360 G5).

You will have to start an agetty process on the COM2 port in order to use the VSP. RHEL 5 example:

  • Add the following to /etc/inittab:
S1:2345:respawn:/sbin/agetty 115200 ttyS1 vt100
  • Run telinit q to have init reread /etc/inittab.

In order to see the startup/shutdown messages on the VSP, add the following to the appropriate kernel line in /boot/grub/menu.lst:

...
kernel /vmlinuz-2.6.18-8.el5 ro root=LABEL=/ console=tty0 console=ttyS1,115200

"Remote Console - in use"

iLO

There does not appear to be an option within the ssh and Web interfaces of the iLO to reset the iLO and clear an "in use" remote console connection.

  • Select Administration, and then Network Settings. Click Apply, and iLO will reset, freeing the remote console.

iLO 2

Two ways:

  • Select Diagnostics, and then click Reset under Reset Integrated Lights-Out 2.
  • Select Administration, and then Network. Click Apply, and iLO 2 will reset, freeing the remote console.

OpenSSH problems with iLO ssh server

The OpenSSH client on my Ubuntu 7.10 system is incompatible with the ssh server on an iLO system with 1.91 firmware. There may be problems with other OpenSSH/iLO versions.

$ ssh -V
OpenSSH_4.6p1 Debian-5build1, OpenSSL 0.9.8e 23 Feb 2007

$ echo "QUIT" | nc iLO 22
SSH-2.0-mpSSH_0.0.1

$ ssh admin@iLO
admin@iLO's password: 
dispatch_protocol_error: type 100 seq 9
dispatch_protocol_error: type 100 seq 10
buffer_get_ret: trying to get more bytes 4 than in buffer 0
buffer_get_int: buffer error

As a workaround, use PuTTY.

Upgrading Firmware

To upgrade iLO/iLO 2 firmware through the iLO HTTPS interface, download the Online ROM Flash Component for Windows, Extract the files, and Send firmware image of the appropriate firmware file (e.g., ilo191.bin). Note that wine for UNIX systems works with the self-extracting .exe file.

Using Virtual Media with the Command-Line Interface

The iLO 2 Virtual Media Java applet does not work well over a low-speed WAN[1]. My Linux ISOs would routinely not boot when using this Java applet.

As an alternative, ISOs may be loaded from an HTTP server using Virtual Media with the iLO command-line interface.

Example:

hutch@hutch:~$ ssh admin@iLO
admin@iLO's password:
User:admin logged-in to iLO(10.215.14.5)
iLO Advanced 1.42 at 08:37:01 Oct 03 2007
Server Name: CZC7124NST00
Server Power: On

</>hpiLO-> vm cdrom insert http://10.215.0.35/kickstart/boot_isos/5Server-i386_boot.iso

(Note: use IPs when specifying an HTTP server)

</>hpiLO-> vm cdrom get
VM Applet = Disconnected
Boot Option = NO_BOOT
Write Protect = Yes
Image Inserted = Connected
Image URL = http://10.215.0.35/kickstart/boot_isos/5Server-i386_boot.iso

(Note: the "NO_BOOT" means that the system will not boot off the "connected" image)

</>hpiLO-> vm cdrom set boot_once

(Note: The next boot will be from the connected image) 

</>hpiLO-> power reset

You will likely want to start a Remote Console via the iLO 2's HTTPS interface.

Rebooting iLO

To reboot iLO without unplugging the power to the system, run the following command on the SMASH interface.

cd /map1
reset

any way to reset ilo without disconnecting power?

Virtual Power Options

From HP Integrated Lights-Out 2 User Guide for Firmware 1.35:

  • Momentary Press button provides behavior identical to pressing the physical power button.
  • Press and Hold is identical to pressing the physical power button for five seconds and then releasing it. This option provides the ACPI-compatible functionality that is implemented by some operating systems. These operating systems behave differently depending upon a short press or long press. The behavior of this option might circumvent any graceful shutdown features of the operating system.
  • Cold Boot of the system immediately removes power from the system. The system will restart after approximately six seconds. This option is not available when the server is powered down. This option circumvents graceful operating system shutdown features.
  • Reset System initiates a system reset. This option is not available when the server is powered down. The behavior of this option might circumvent any graceful shutdown features of the operating system.
