Make a copy of the license details.

Create USB imaging media

This process should be used to create the image media for any system listed as Generation 8 appliances, as well as Generation 5, 6 or 7 appliances compatible with 10.2 or newer imaging media.  For legacy Generation 5, 6 or 7 appliances, Create a bootable USB Flash Drive (Alternate Method) may be used as an alternative to using Rufus. Need help determining the generation of your appliance or which ISO to use? See Which Image Media Does My Unitrends Appliance Use?

  1. Download RUFUS (https://rufus.akeo.ie/)
  2. Obtain the most recent ISO factory image your appliance supports image ISO from here.  Reference Which Image Media Does My Unitrends Appliance Use? for the correct media release.  IMPORTANT!   Imaging media is specific to the appliances listed in this kb. If the incorrect media image is used, you will not be able to complete the reimage process. Make sure you have the correct image before proceeding!
  3. Burn that image to USB using Rufus:  Imaging should be done to a UBS 2.0 device of 4GB, 8GB, or 16GB (See note below).
     IMPORTANT!   This will ERASE your USB device!

Reimage Process for Generation 5, 6, 7 or 8 systems using current version USB media

  1. Once the USB is prepared, and safely removed from your Windows system.
  2. Disconnect any tape hardware and remove archive disks from any bays before proceeding. NEVER image a system while archive devices are attached. 
  3. Shut down and completely power off the Unitrends appliance.  Running appliances will not re-POST to detect the USB boot device, they must be powered off and have the device connected in that state and boot cold.  
  4. When you insert the USB thumb drive, please make sure use the correct USB port for your USB device.  The black port supports USB 2.0 and is the only port that should be used.  The blue port supports USB 3.0 but may not function correctly during the imaging process.
Hint:   If you are experiencing issues during the imaging process, please be sure the image is burned properly and the USB drive is add only after the system was fully shut down (see step 3).
  1. Once it is in the the USB slot inserted full, please power on the Unitrends system
  2. On many models, you may be prompted to press F-10 to select a boot device.  Doing so "may" present the USB device as a boot option.  If so, select the USB device to boot and proceed to step 12 below.  If F-10 does not allow booting to USB, restart the appliance and proceed with the steps below to set your BIOS boot order manually. 
  3. At the bios splash screen on boot, press the DELETE key to enter the BIOS when prompted. If you are asked for a password enter: backup
  4. Use the arrow keys and select the BOOT option, then select Hard Disk Drives. Document what is listed for disks as their order.

AFTER REIMAGE...

  • You will need to set the IP Address and DNS settings using the Unitrends Backup Initial System Setup Menu:
    1. To configure the IP Settings, select:  1.  Network Setup (then) 1.  Configure IP, Netmask and Gateway
    2. You should still be in  Network Setup. To set the DNS, select:  2.  Configure DNS
    3. You can now use Google Chrome to connect to the Unitrends Web Administrative Interface and complete the Setup Wizard.
  • After completing the Setup Wizard, you will need to set Instant Recovery to 1% following using the KB titiled Newly imaged Recovery-Series system (or Reimage) - no backups complete, 1%, or out of space .
    NOTE: If you do not do this steps, you will get Out of Space messages.
  • You can now license your Unitrends System.
  • If you have been making cold backup copies of your appliance you may now follow the Appliance Disaster Recovery steps from the administrator's guide to import your appliance's prior configuration, backup jobs, and protected asset associations.  If you have only been making backup copies to another privately-owned Unitrends appliance (Hot backup copies other than to Unitrends Cloud) your appliance does not have the Cloud Self-Service feature required to import the system metadata backup to perform disaster recovery from the backup copy connection.  To perform disaster recovery in this scenario you may follow the steps from KB 6390.

 

Reimage Process for legacy systems using DVD media

This process is only used today when imaging with Generation 4 or older systems using the 7.4 or 6.1 image media.  please download this media and burn it to a physical DVD disk before proceeding.  Ensure you use a proper ISO imaging application and utilize a verify burn option. 

Step 1

  • Remove any archive devices and/or drives.
  • Please remove any tape drives.                                            

*****Verify if there is a 10G NIC installed in your appliance**** 
If present, the NIC will need to be temporarily removed during the reimage process. 
Once the reimage has completed the NIC can be reinstalled.

  • Insert the imaging disk in the appliance's DVD drive and boot the device to the disk.  

Step 2

Select Image Appliance Appliance (Old-Models) from the Image menu and press Enter
Note:  Next-Generation appliances are denoted by a "S" following the first three digits in their asset number and are not shipped with a DVD drive.  For USB imaging, see Reimage a Next Generation or S-series appliance using USB.

NOTES
Additional relevant information such as links to third-party references, specific exceptions, warnings, etc.

Backup Versions:

ROS8003_usb.el6.x86_64-[timestamp].bin and above

Required Software/Hardware:

 

For generation 4 and older systems that require imaging with 7.4.0-3 image media, additional steps are required.  These steps do not apply if you have successfully imaged your system with 10.0 or higher media. 

  1. Ensure your appliance can reach the internet with your appliance.  
  2. Update your appliance to release 9.1.1-3 using the legacy web UI
  3. Check this article for Cent OS 6 Migration Prerequisites for Physical Appliances
    • If your system passes pre-check and is compatible with Cent OS 6, contact Unitrends Support and they will provide information on how to migrate to CentOS 6.  This must be completed prior to performing a System recovery from archive or before adding and configuring clients if supported by your system.  Note, Support for this process is limited or potentially refused after Aug 31 2017 as migration services under Unitrends Support were communicated as no longer covered or available after this date.    
    • If your system is not compatible with CentOS 6 or if an offer to assist in migration is rejected, then your system is at the latest supported release as of 9.1.1-3, and you will need to contact a Unitrends Partner or Sales Rep in order to replace your appliance and utilize newer software.

NOTES

USB Devices greater than 16GB:  We recommend using USB devices between 4GB and 16GB as it eliminates the problems in formatting and is what our Quality Assurance team has tested it successfully on. The USB device must be be formatted using the MBR.
