Activation ou désactivation de la redirection HTTPS
Si vous souhaitez désactiver la redirection automatique de HTTP à HTTPs, soit en raison de problèmes d’avertissement liés au certificat
iDRAC par défaut, soit pour en faire un paramètre temporaire à des fins de débogage, vous pouvez configurer l’iDRAC de telle sorte que
la redirection du port http (80 par défaut) vers le port https (443 par défaut) soit désactivée. Par défaut, il est activé. Vous devez vous
déconnecter et vous reconnecter à l’iDRAC pour que ce paramètre soit appliqué. Si vous désactivez cette fonctionnalité, un message
d’avertissement s’affiche.
Vous devez disposer du privilège de configuration d’iDRAC pour activer ou désactiver la redirection HTTPS.
Un événement est enregistré dans le fichier journal du Lifecycle Controller lorsque cette fonction est activée ou désactivée.
Pour désactiver la redirection du protocole HTTP vers HTTPS :
racadm set iDRAC.Webserver.HttpsRedirection Disabled
Pour activer la redirection du protocole HTTP vers HTTPS :
racadm set iDRAC.Webserver.HttpsRedirection Enabled
Pour afficher l’état de la redirection de HTTP vers HTTPS :
racadm get iDRAC.Webserver.HttpsRedirection
Using VNC client to manage remote server
You can use a standard open VNC client to manage the remote server using both desktop and mobile devices such as Dell Wyse
PocketCloud. When servers in data centers stop functioning, the iDRAC or the operating system sends an alert to the console on
the management station. The console sends an email or SMS to a mobile device with required information and launches VNC viewer
application on the management station. This VNC viewer can connect to OS/Hypervisor on the server and provide access to keyboard,
video, and mouse of the host server to perform the necessary remediation. Before launching the VNC client, you must enable the VNC
server and configure the VNC server settings in iDRAC such as password, VNC port number, SSL encryption, and the time-out value. You
can configure these settings using iDRAC Web interface or RACADM.
NOTE: VNC feature is licensed and is available in the iDRAC Enterprise or Datacenter license.
NOTE: You may see VNC login error if you are using Chrome browser.
You can choose from many VNC applications or Desktop clients such as the ones from RealVNC or Dell Wyse PocketCloud.
Two VNC client sessions can be activated simultaneously. Second session is in Read-Only mode.
If a VNC session is active, you can only launch the Virtual Media using Launch Virtual Console and not the Virtual Console Viewer.
If video encryption is disabled, the VNC client starts RFB handshake directly, and an SSL handshake is not required. During VNC client
handshake (RFB or SSL), if another VNC session is active or if a Virtual Console session is open, the new VNC client session is rejected.
After completion of the initial handshake, VNC server disables Virtual Console and allows only Virtual Media. After termination of the VNC
session, VNC server restores the original state of Virtual Console (enabled or disabled).
NOTE:
● While launching a VNC session, if you get an RFB protocol error, change the VNC client settings to High quality and then relaunch
the session.
● When iDRAC NIC is in shared mode and the host system is power cycled, the network connection is lost for a few seconds.
During this time, if you perform any action in the active VNC client, the VNC session may close. You must wait for timeout (value
configured for the VNC Server settings in the Services page in iDRAC Web interface) and then re-establish the VNC connection.
● If the VNC client window is minimized for more than 60 seconds, the client window closes. You must open a new VNC session. If
you maximize the VNC client window within 60 seconds, you can continue to use it.
