Rescue

The rescue system is a live system. Data is not stored permanently in it.

Common tools for diagnosis, troubleshooting and server configuration and are pre-installed in the rescue system.

You can start the rescue system at any given time in CloudHub and provide your SSH public key. The server will be restarted and booted in the rescue system.

Once started, you can login as user rescue via SSH and your SSH public key - the same IP addresses and firewall rules apply as usual:

ssh rescue@bmcXXXXXX.bmc.psmanaged.com

The server can be restarted as often as desired, you have to explicitly stop the rescue system in CloudHub.

Examples

mount "$(fdisk -l | grep EFI | awk '{print $1}')" /mnt/root/boot/efi/
