If you administer a data center, service disruptions and data integrity issues are probably your worst nightmare.  EMC Technical Advisories (ETAs) alert you to potential hardware or software issues that could have serious negative impacts on your production environment, such as data loss, data unavailability, or significant loss of system functionality.

EMC Isilon ETAs provide time-critical information about technical issues that affect EMC Isilon products. The advisories include specific details about an issue and instructions to help prevent or alleviate the problem. There are a few different ways to track ETAs. Whichever method or combination of methods you use, pay special attention to ETAs with the impact severity rating of critical.

Keep up with the latest ETAs by:

To learn how to set up ETA email alerts, you can watch this video: How to Set Up an Email Event Notification in OneFS.

During our July “Ask the Expert” session, you shared experiences and ideas about Isilon technical content. The new EMC Isilon Current Patches Info Hub is a direct response to your requests for help in quickly determining whether or not content is relevant to you – in this case, content about Isilon OneFS patches.

Concise information about OneFS patches is now available on the new EMC Isilon Current Patches Info Hub. This is the place to find summaries of recently-released patches from EMC Isilon Engineering. Patches are grouped by OneFS release, starting with the most recent releases and patches. The summaries are designed to help you quickly determine what the patch addresses, how important it is, and whether or not you need it.

The Current Patches Info Hub supplements the Current Isilon Patches document.  Use the Current Patches Info Hub to determine whether or not you need a patch. If you do, go to the Current Isilon Patches document for more information about the patch, including the complete description and instructions for downloading and extracting the patch files.

You must be an EMC customer to download Isilon patches. You’ll need to log in to EMC Online Support with appropriate credentials to access the detailed patch READMEs and to download patches.

Check out the EMC Isilon Current Patches Info Hub and let us know what you think. If you have feedback for us about this or any other Isilon technical content, email us at And thank you!
