Hey,
Many thanks for the support. i have tried root/default on the console but no luck. Doc listed in SOL3350, is great. Just want to see if this is for VE or for physical appliance. As i have tried but it does not allow me to select different boot image. In Fact this has only one image. Even if i try to press "e" to edit the boot image or edit the line, nothing happens.
So thought to check if the instructions are for VE or physical appliance.
To boot the BIG-IP system into single-user mode, perform the following procedure:
Note: To perform the following steps, you must be local to the BIG-IP system with a console connection or using a console server.
Connect a terminal to the BIG-IP serial console port.
Reboot the BIG-IP system.
While booting, the BIG-IP system displays the GRUB menu and counts down before continuing the boot process.
Before the countdown expires, use the up and down arrow keys to select the appropriate boot image.
Note: Alternately, press SHIFT+6 (^) to arrow up, and press the v key to arrow down.
Press the e key to edit the boot options.
A new GRUB menu screen displays.
Use the up and down arrow keys to select the line that begins with kernel /boot/vmlinuz.
Note: Alternately, press SHIFT+6 (^) to arrow up and press the v key to arrow down.
Press the e key to edit the line.
Add the word single to the end of the kernel /boot/vmlinuz line, and then press the Enter key.
For example:
kernel /boot/vmlinuz single
