Offline upgrading using ISO

Overview

It's not always possible to upgrade QuantaStor using online repositories. There may be security risks associated with allowing an appliance to access the internet.

Detail

In a closed environment, it is possible to upgrade QuantaStor using an ISO, which can be sourced from our website. It is important to ensure that you have the latest ISO, and for the correct distribution. Before continuing, please speak with OSNEXUS Support (support@osnexus.com) if you are unsure what distribution you are using.

2. Copy ISO to system to /home/qadmin
3. SSH to system and elevate to root (sudo -i)
4. Make directory for ISO (mkdir /mnt/iso)
