This page documents the basic steps of upgrading the Isilon OneFS operating system. This specific upgrade was from 220.127.116.11 to 18.104.22.168 but the process and screenshots should be accurate for any 7.x upgrades.
- If possible, perform a cluster reboot or reboot each of the nodes individually roughly 2 weeks prior to the OS upgrade
- Skipping this step may cause the OneFS upgrade to fail on the last step.
- Download the new version of OneFS from support.emc.com (PowerLink account reqd)
- Click Downloads
- Under Find a Product, type Isilon OneFS and hit enter
- Browse to the desired version of OneFS on the left hand side
- Expand the Full Release section
- Download the package that ends in installation file
- Place this installation file somewhere on the Isilon cluster that will be upgrade
- If upgrading from 6.x -> 7.x or 7.1 -> 7.2 then a full cluster reboot will be required as opposed to a rolling upgrade.
- Login to the Web GUI for the Isilon cluster that will be updated
- Click Help -> About this Cluster in the top right
- Click Browse and locate the installation file that was download in the prep-steps
- Click Submit
- This will kickoff a series of steps. Some will be automated and some will prompt for input. The large steps are listed below
- Pre-Upgrade Check – Will only be shown if there are warnings/errors in the cluster log
- Connecting to remote and local upgrade processes
- Loading Image – This step might take a few minutes
- Upgrade Mode – Some updates, such as from 6.x -> 7.x and from 7.0 -> 7.1 will require a simultaneous upgrade. Others will roll the upgrade through the nodes without taking the cluster down.
- Loading Image
- Installing Image
- Restoring User Changes
- Upgrade Install Successfully
- Prompts for reboot of cluster
- Shutting down services – If a reboot of the nodes/cluster hasn’t been performed recently this step tends to hang.
- After all of the nodes have shutdown their services a cluster reboot is initiated
- Once the cluster reboots the upgrade is complete
- Verify cluster health by logging into the Web GUI or issuing the following command via SSH
