Accessing the Blade
To access the IPMI interface, we redirect port 443. The console display also requires port 5900.
It is not possible to bind 443 with SSH as non-root ; to avoid connecting as root we use
socat to redirect the privileged port.
ssh -L 5900:172.24.31.24:5900 -L 8443:172.24.31.24:443 email@example.com sudo socat tcp-listen:443,reuseaddr,fork tcp-connect:127.0.0.1:8443
Before connecting, be sure to install the Java JRE (
apt get install default-jre on Debian).
Then you can connect to the interface using
After authentication, you get this question:
You need the latest Java(TM) Runtime Environment. Would you like to update now?
to which you can simply reply
From here you control the Blade’s power.
Click on the console screenshot (sometimes broken) and access the Java application. After trusting the application you can now use the remote console.
When you reboot the screen size changes many times, which is very annoying, so I would suggest using a fixed-size window by disabling the
Auto-resize window setting in the
Note you can also control power from the console interface.
You may have to reboot and select the right menu to choose PXE. One of the interfaces of the blade should be in the
OSAS-Provisioning VLAN and should catch DHCP and propose an installation menu. You should have access to manual and basic automated installation for classic OSes, and maybe tenant/topic-specific automated installations if there are.
If no DHCP is caught, then most probably the switches needs to be reconfigured to change the network assignation. Also beware not all blade interfaces are able to boot on PXE.
Finding Provisioning IP
You can find the provisioning IP using a special playbook:
ansible-playbook --diff -l <bladename> playbooks/find_prov_ip.yml
Red Hat Systems
On Red Hat OSes the graphical installation is accessible via VNC.
After installing a VNC client, you need to redirect port
5001 to the provisioning IP of the blade:
ssh -L 5901:<blade-prov-ip>:5901 firstname.lastname@example.org
And finally access the graphical installation:
The VNC password is available on the OSAS Vault.
On Debian systems you can continue on the console redirection, activate another TTY and use
screen to control the text mode installation.
