Flashing Riverbed Ex-560 to R210 ii BIOS & Password & IDRAC6 resets

  1. Use Rufus to make a bootable freedos USB
  2. Download the latest r210ii bios – https://dl.dell.com/FOLDER04826304M/1/PER210II_020900.exe and put it on the USB you just made
  3. Boot the server up and boot to the USB
  4. Execute the following 
per210ii_020900 -wipeclean -forcetype

Your server should now be flashing and it will reboot shortly

If you need to have the password for the BIOS and the IDRAC password reset , then you will need to open up the case. Locate the CMOS battery and then change the following jumper (at 7 oclock position of the battery and right of the four colour plug).

Power on the server and all the password should be gone.

Revert the jumper back to original position once done.

Installing Omada Controller 4 on linux

Since Omada 4 doesn’t contain java and mongodb with the installer package, you will need to install it manually first.

This is the guide for CentOS7

Java

 yum install java-1.8.0-openjdk -y

MongoDB

touch /etc/yum.repos.d/mongodb-org.repo

Paste the following into /etc/yum.repos.d/mongodb-org.repo

[mongodb-org-3.4]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/3.4/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-3.4.asc

yum install mongodb-org
systemctl enable mongod
systemctl start mongod

Recovering ESXi root Login

  1. Boot the server up with a linux disc, such as CentOS 7 in recovery mode
  2. Once booted, mount 250MB partition. Usually /dev/sda5. mount /dev/sda5 /mnt
  3. cd to /mnt
  4. Copy state.tgz to /tmp cp state.tgz /tmp
  5. cd to /tmp, then extract state.tgz. cd /tmp; tar -zxvf state.tgz
  6. Extract local.tgz. tar -zxvf local.tgz
  7. Open the /tmp/etc/shadow file using your favorite text editor. nano /tmp/etc/shadow
  8. Under your root (or account with root), remove the shadow password. The resulting row may look like this. root::13358:0:99999:7:::
  9. Now repack all the files back in. cd /tmp; tar -zcvf local.tgz etc; tar -zcvf state.tgz local.tgz
  10. Copy the state.tgz back into /mnt. cp /tmp/state.tgz /mnt;
  11. Now reboot the server. Once ESXi is booted back online, you will be able to log into your root with a blank password.
