Note – this process will completely destroy all configuration and data on the ZFS Appliance. I only need to do this when a system is returned to me with an unknown IP and password, but I can get onto the ILOM. Please contact Oracle Support before doing this and truly understand what you are doing.
Normally, if you can login to a system you can issue the command ‘maintenance system factoryreset’ to get this result. DO NOT DO THIS IF YOU HAVE ANY DATA YOU NEED ON THE APPLIANCE.
First – ensure that you are on the current version of Firmware/BIOS on the ZFS Appliance. This can be checked using MOS document 1174698.1 Oracle ZFS Storage Appliance: How to check the SP BIOS revision level as you could encounter problems editing the grub menu.
Login to the SP/ILOM -> start /SYS -> start /SP/console
Wait for the GRUB menu which will be editable for 10 seconds.
Within the 10 seconds, Press ‘e’ on the keyboard
Select the line kernel … To navigate, use ‘v’ to go down and ‘^’ to go up.
Press “e” on keyboard to edit this line
Append ” -c” to this line (spell as “space minus c”)
change this :
kernel$ /platform/i86pc/kernel/$ISADIR/unix -B zfs-bootfs=system/368,console=ttya,ttya-mode="9600,8,n,1,-"
to this :
kernel$ /platform/i86pc/kernel/$ISADIR/unix -B zfs-bootfs=system/368,console=ttya,ttya-mode="9600,8,n,1,-" -c
Finally press “b” on keyboard to reboot.
This will print the following lines :
SunOS Release 5.11 Version firstname.lastname@example.org,1-1.1 64-bit Copyright (c) 1983, 2013, Oracle and/or its affiliates. All rights reserved. Use is subject to license terms. > Clearing appliance configuration ...... done. Configuring network devices ... done.
The system will then wipe all of the previous configuration, reboot, and allow you to reconfigure the networking and root password.
Note: The change you made to the grub boot menu is temporary, and so you should not need to go back in and edit it again.
