If you’ve started using Isilon’s Self-Service Platform, you know how useful its health checks and troubleshooting assistance can be. If you aren’t familiar with the Self-Service Platform, see our previous blog post.

EMC Isilon’s Serviceability team is continually working to improve the tool by adding new capabilities. For example, one new feature in version 1.5.6 checks for outdated patches installed on the cluster. Another new feature tells you whether any EMC Technical Advisories (ETAs) might affect your cluster.

To make sure that you have the most up-to-date version of the tool, visit the Self-Service Platform Info Hub. On the Info Hub, you can download the tool, read the latest documentation, and start a discussion with the development team.

As always, we look forward to hearing from you about your experience.

We’re on a roll!  EMC Isilon InsightIQ 4.0 is available now. If your mission includes monitoring and analyzing the performance and file systems of Isilon clusters, InsightIQ is your hero.  It provides powerful performance monitoring and reporting tools to help you maximize the performance of your EMC Isilon scale-out storage system. InsightIQ includes innovative, advanced analytics to optimize applications, correlate workflow and network events, and accurately forecast future storage needs.

InsightIQ 4.0 Cool New Features

You can use InsightIQ to check that your cluster is operating at peak performance, compare changes in performance across metrics such as network traffic, client activity, and CPU usage, correlate critical cluster events with performance changes, determine how workflows, software, and systems affect cluster performance over time, create reports to help identify performance bottlenecks or to validate a theory, and more.  And of course, InsightIQ 4.0 is fully compatible with OneFS 8.0.0.0 and IsilonSD Edge, right down to InsightIQ cleverly leveraging the benefits of the redesigned OneFS 8.0.0 File System Analytics job. And InsightIQ 4.0 is now available as a $0 licensed product, which means that you can get community support through the EMC Community Network (ECN) Isilon Community.

But wait, there’s more:

  • You can monitor and predict usage of Isilon storage clusters. Prediction is based on the rate of growth of capacity usage over time and extrapolated to identify when the capacity reaches 90%.
  • You can take advantage of the enhanced dashboard, including at-a-glance infographics that provide current health, status, and operations information for your monitored cluster:
IIQ4 dashboard

InsightIQ 4.0’s enhanced dashboard infographics display current health, status, and operations information. (Click for larger image.)

  • You can easily monitor IPv6 data breakouts. InsightIQ 4.0 reports IPv6 breakouts as separate clients instead of presenting them as one big generic IPv6 client group.
  • You can optionally communicate telemetry data to EMC through EMC Secure Remote Support.

More information

To learn more, check out the InsightIQ Info Hub. There you’ll find a fascinating collection of InsightIQ-related information, including release notes, user and installation guides, videos, and links to EMC Community Network (ECN) blog posts and discussions.

If you’ve been tuning in to the Cluster Talk audio podcast, you’ll know that there’s a segment each episode called “Cool Commands” where they talk about a OneFS command and its application. As an extension of this, we’ve created a video-based version of Cool Commands that focuses on how to find out general or specific information or complete certain tasks.

The first episode describes how to find basic cluster health and job information using commands like isi status and isi job status. In the video, you’ll see the command syntax and we’ll highlight important parts of the output. You’ll also learn how to interpret the output to identify potential issues that might affect your cluster’s performance. The second and third episodes describe how to troubleshoot file access issues on Windows and UNIX clients, respectively. These episodes include a great analogy for how permissions work and step by step troubleshooting to resolve a file access issue.

In future episodes, we’ll describe how to change permissions on UNIX files and folders using chmod and changing the ownership of UNIX files and folders using chown. All the Cool Commands episodes are published on the Isilon Support playlist on EMC’s YouTube Channel. If you have any questions about the videos or suggestions for future episodes, we’d love to hear from you.

OneFS authentication is implemented for many different storage environments and authentication requirements can differ from setup to setup. Background authentication processes (daemons) add complexity to configuring authentication. Issues can and do arise. But help and guidance are readily available!

Check out Fragile Cogs: Starting and Stopping OneFS Authentication Processes  on the Uptime Information Hub for information and advice about starting and stopping authentication daemons. (Hint: Follow the instructions or call EMC Isilon Technical Support first.)

Latest posts by Risa Galant (see all)

Heads up – EMC Isilon OneFS 7.0.x reaches the end of its service life (EOSL) on November 30, 2015. If you are running any version of the OneFS 7.0.x family, we encourage you to upgrade to the latest Target Code release in the OneFS 7.2.0 family before November 30, 2015. See the Target Code table on the Uptime Information Hub landing page for a list of recommended OneFS Target Code versions and release notes.

Note: if you call Support to open a case after the November 30 EOSL date, you will be directed to upgrade to a supported OneFS family. Support might still triage your issue, but only on a limited basis, and no patches will be offered or available.

Upgrading to OneFS Target Code

OneFS Target Code is a version of OneFS that has proven, through extensive use in the field, to surpass the high bar set for all OneFS releases. If you need help at any point in the upgrade, contact EMC Isilon Technical Support or your account team. See Upgrading to OneFS Target Code for more information.

More information about OneFS 7.0.x EOSL

For more information about OneFS 7.0.x End of Service Life, Target Code, upgrade path options, and more, see the Uptime Info Hub article OneFS 7.0.x will reach its End of Service Life (EOSL) on November 30, 2015.

The big deal about ETAs

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.

Information Experience “Ask the Expert” follow-up

Thank you! The Ask the Expert session featuring the EMC Isilon Information Experience team was a lively exchange. It was great to share experiences and ideas about Isilon content with you. In this follow-up post, we’ll update you about what actions we’re taking based on your suggestions.

Finding just what you need, quickly

One item that came through loud and clear is that we produce a lot of dense information about Isilon products. Those of you who manage several EMC platforms can get inundated, and sorting out what’s important from what can wait can be quite a task. We should make it a lot easier and faster for you to find just what’s relevant to you. We’ve created a proposal for doing that which is now in review.

Cool Commands videos

Thanks for the great ideas for the new Cool Commands video series.  The first batch of videos will cover broad commands, and you’ll see more specific commands like isi statistics covered in subsequent videos.

When in doubt, script with the OneFS API

Command line interface (CLI) commands can change from release to release and that can be a source of concern. We have the answer for you: the OneFS Platform API (PAPI). Even if the underlying CLI commands change for a particular release, PAPI scripting will be consistent from release to release. Check out the OneFS API Info Hub and OneFS Uptime Hub for information about getting started.

New! Updated! Lookie!

Oh yes, those New! and Updated! tags on our Info Hubs can be distracting. Special notices can really clutter up the content, too. You let us know that if tags and notices are left up for too long, they can be confusing. So we’ll remove New! and Updated! tags after 2 weeks and remove notices as soon as they’re no longer relevant.

Your feedback is invaluable – don’t be shy about letting us know about your experience accessing and using EMC Isilon technical content. Email us at isicontent@emc.com with your feedback. And thank you!
