How to Boot the KVM/net in Single User Mode
The KVM/net has a single user mode that is used when:
1. The name or password of the user with root privileges is lost or forgotten.
2. When an upgrade or downgrade process does not work properly and the
system turns unstable.
3. When a configuration change leaves the KVM/net inoperative or unstable.
Note: You cannot perform this process using Telnet or other remote connection
protocols.
T To Boot the KVM/net in Single User Mode
1. Connect a terminal to the console port of your KVM/net, login as “root”,
and reboot the unit.
The initial output of the hardware boot process is shown below.
2. After the line
“Linux/PPC load: root=/dev/ram” is displayed, the
system waits approximately 3 seconds for user input.
3. Type “<sp>single” (spacebar, then the word “single”).
Hardware boot.
