ILO3 Notes

The ILO 3 card on the HP Prolient DL380 allows us complete remote control of the server for this reason the same security precautions which are used on the idrac6 need to be implemented.

Securing the ILO3

The ilo3 is not directly accessible accept through the admin lan firewall. Eventually this will require vpn access however in the mean time it is accessed through port redirection. The ilo3s main access is through https. The port number for this is configurable along with the other ports used. (ssh + 2 ports for console redirection)

[[Image(ILO3Notes:ilo3NetworkPorts.png)]] Unless you are working in a MAAS environment the ipv6 should be disabled and the ipv4 address should be made static. This will require resetting the ILO3 itself. [[Image(ILO3Notes:ILO3ResetILO.png)]]

Manage Admin Accounts

Create user and management accounts as soon as possible and demote or remove any existing accounts. [[Image(ILO3Notes:ilo3UserAdmin.png)]] While there you should add your ssh keys for ssh connections. Note that only dsa keys are supported so you my need to create a separate public key.

steve:~ don$ ssh-keygen -t dsa
Generating public/private dsa key pair.

Java Console

The ILO 3 provides a java console similar to the one provided by the Dell idrac. It requires the remote console port (17990) as well as the Virtual Medea Port (17988) to function properly. [[Image(ILO3Notes:HPBootSplash.png)]]

Remote Media

Attaching an iso is straight forward. [[Image( ILO3Notes:ilo3RemovableMedia.png )]] Using the Ubuntu 18.04 Live Server over a DSL connection is pokey and complains a lot but it does not fail. [[Image(ILO3Notes:ilo3NetworkMountsAndLag.png)]]

Enabling bios and console accèss via ssh.

Once you have administrative access to the ILO3 and you have an os install you can do everything vial ssh. Much like the idrac you need access to the f9 key. [[Image(wiki:Idrac6:fnkeys.png)]] * Enter bios * Select Serial settings. * set console redirection to com2 _ you will have to do this in the advanced settings as well _ [[Image(ILO3Notes:ILO Bios Virtual Serial Port.jpg)]]

Connecting to the console

Once the bios is set up you can ssh to the console using your iso credentials and ssh key.

fixing grub (identical to the process for idrac 6)

You need set the console to ttyS1 by adding a console=ttyS1,115200n8 to the end of the kernel line

root@bs2020:~# nano /boot/grub/menu.list
kernel          /boot/vmlinuz-4.4.0-96-generic root=UUID=8cafbdf6-441e-4f76-b89c-017fc22253f9 ro console=hvc0 console=ttyS1,115200n8

Add the changes to /etc/default/grub so that it will survive updates to the kernel.

root@bs2020:~# nano /etc/default/grub
GRUB_TERMINAL='serial console'
GRUB_CMDLINE_LINUX="console=hvc0 console=ttyS1,115200n8"
GRUB_SERIAL_COMMAND="serial --speed=115200 --unit=1 --word=8 --parity=no --stop=1"
root@bs2020:~# update-grub

Reboot the server and attach to the console. [[Image(ILO3Notes:ILo3SerialBootScreen.png)]] [[Image(ILO3Notes:ILO3SerialConsoleBootFinish.png)]]

virtual serial port in action

In order to make the dl380 expose the disks we added required jumping into the raid controllers bios during boot and configuring it. This is documented [[wiki:CaptiveRaidController|here]]
