To reset your password, you must have access to the serial console or monitor and be able to see the entire boot process to perform these steps:
1. Start, or reboot the appliance.
2. Once you see the "Press any key to continue" message, press a key.
3. Immediately press E.
You should see a GNU GRUB menu.
For a Steelhead upgraded to 4.0 from 2.0 or 3.0, the menu prompts you to select the Riverbed Steelhead, diagnostics, or a restore/recovery image. Select Riverbed Steelhead and skip to Step 5.
For a Steelhead manufactured with 4.0 (that has not had previous versions), the menu prompts you to select the disk image to use. Continue with Step 4.
For software versions prior to 4.0, the menu displays root and kernel parameters. Skip to Step 6.
4. Press V or ^ to select the disk image to boot.
5. Press E.
Another GRUB menu appears, with options similar to these:
0: root (hd0,1)
1: kernel /vmlinuz ro root=/dev/sda5 console=tty0 console=ttyS0,9600n8
6. Press V or ^ to select the kernel boot parameters entry.
7. Press E to edit the kernel boot parameters.
You should be given a partially filled in line of text.
8. Append " single fastboot" at the end of this line. Note the space before 'single', it is very important. (And do not enter the quotes.)
9. The line of text will contain TWO "console=" entries. Delete the one containing "tty0" (unless you are using a keyboard/monitor on the Steelhead, in which case delete the one containing "ttyS0").
TIP: Use the arrow keys to access the entire command line.
10. Press Enter.
11. Press the B key to continue booting.
The system starts.
12. Once at the command prompt, type "/sbin/resetpw.sh" and press Enter.
The password will be blank.
13. Type "reboot" and press Enter to reboot the appliance.
