Resetting a lost password
To reset your password, you must have access to the serial console or monitor and must be able to see
the entire boot process to perform these steps:
1. Start or reboot the appliance.
2. When prompted, press any key to continue.
3. Immediately press E . A GNU GRUB menu appears.
– 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. Select the disk image to boot.
5. Press E .
A GRUB menu appears, with options similar to the following:
-----------------
0: root (hd0,1)
1: kernel /vmabcxyz ro root=/abc/sda5 console=txxx console=txxxx,9xxxxx
-----------------
6. Select the kernel boot parameters entry.
7. Press E to edit the kernel boot parameters. The CLI displays a partially completed line of text similar
to the following:
The SteelHead fails to boot. Ensure that the power strip or the uninterruptable power supply (UPS)
the SteelHead is plugged into is turned on and is functioning properly.
Your SteelHead does not boot and is
beeping, which can be due to a RAID
error or a failed power supply. First, determine whether the cause of the beeping and failure to boot is a
RAID error.
To determine if there is a boot failure
1. Use a keyboard and monitor to connect to the SteelHead.
2. Run the megamgr utility to check for a hard disk failure.
3. If there is a single hard disk failure on a SteelHead, you can use the
extra hard disk in slot 12 to replace the failed disk. For assistance, or
if there is a hard disk failure on more than one disk in a SteelHead or
on any other SteelHead model, contact Riverbed Support at https://
support.riverbed.com.
If the beeping and failure to boot are not caused by a RAID error, they
could be due to a defective power supply. For assistance, contact
Riverbed Support.
