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.

The self-encrypted drives erasure puzzle

Latest posts by Risa Galant (see all)

Self-Encrypted Drives (SEDs) provide hardware-level security for sensitive on-disk data. Data on SEDs is encrypted using a combination of an internal key and a drive access password. Using SEDs is simple. After performing initial drive set-up, you don’t have to do anything: SEDs handle data encryption and decryption automatically. If you want to access the data, you have to know the password. And without that password, the protected on-disk data is inaccessible.

But what if something goes wrong? Can you recover the encrypted data if the password or internal keys are lost or deleted? What if someone removes a SED from a powered-on node, or a SED becomes corrupt or is otherwise defective? What if business reasons require that you completely erase the drive? How do you safely go about doing that, and how do you verify the erasure?

To find answers to these questions, check out the Uptime Information Hub article Data erasure and SED drives: An overview and FAQ, available on the EMC Community Network’s Isilon community space. You’ll learn:

  • How SEDs work
  • What happens if a password is lost, a drive becomes defective, or someone tries to make off with the drive
  • How to erase a defective drive and how to erase all SEDs in a node or cluster
  • How to confirm that a SED has been erased
  • How long typical erasure operations take

There’s a new series in town: the Multiprotocol Concepts series on the EMC Community Network (ECN) Isilon community. If you’ve ever wondered how OneFS handles multiprotocol data access or even what it is, this series will be a great place to start learning all about it. The first blog post introduces basic multiprotocol concepts, setting the stage for subsequent posts that explore those concepts in more depth. We’ll post new series topics approximately every two weeks. Topics include:

  • Data access tokens, also known as unified access tokens
  • Directory services
  • User mapping
  • ID mapping
  • On-disk identity
  • OneFS storage of file and share permissions
  • POSIX permissions
  • Access control list (ACL) policies
  • Verifying your multiprotocol environment and some basic troubleshooting

I’ll list the series posts here as they become available. So take a look at the multiprotocol series. And please let us know what you think!

Introducing the Isilon API Info Hub

Would you like to automate routine Isilon cluster administration tasks? Maybe you need a custom tool to monitor your cluster, or your cluster administrators would like a nice, tidy script to allow them to consistently and securely perform operations on files and directories. If you’re looking for resources to help you do any or all of these things, we have just the place to get started: the Isilon API Info Hub.

The brand-new Isilon API Info Hub is your one-stop shop for information about getting and using the OneFS API. Use the OneFS Platform API (PAPI) to automate configuration, management, and monitoring of tasks, and to build scripts to allow your cluster administrators to securely perform operations on your Isilon cluster’s files and directories.

Isilon API Info Hub resources

The Isilon API Info Hub collects resources such as:

  • Code samples
  • Advice from Isilon API experts
  • Links to related ECN discussions
  • Links to the Isilon OneFS Platform API documentation

And much more.

How PAPI works

You can access PAPI through a Representational State Transfer (REST) interface, which is composed of URIs and standard HTTP methods. That means that you can manage cluster resources using HTTP methods such as GET, POST, PUT, and DELETE. OneFS and PAPI exchange the representations of objects and collections as JSON-formatted documents, so they’re platform- and programming language-independent. When PAPI sends a request to OneFS, the request is authenticated and then authorized through role-based access control (RBAC). When the request is approved, you got access, baby, and the requested operation proceeds.

Well, if you’ve enabled HTTP on your cluster, that is. PAPI relies on HTTP to function correctly. Be sure that HTTP is enabled on your cluster so that your scripts work.

Check out the Isilon API Info Hub and be sure to let us know what you think. And check out the Isilon Uptime Info Hub for technical information about Isilon products and related real-world problems and solutions, including best practices for scripting with PAPI. Happy scripting!

EMC Isilon OneFS 7.2.1 is available!

Latest posts by Risa Galant (see all)

EMC Isilon OneFS 7.2.1 release has some great new and updated features that provide benefits on both the hardware and software side, including:

  • Security Technical Implementation Guide (STIG) configuration support
  • FIPS OpenSSL support
  • CAC/PIV authentication
  • Enhanced IPv6 support
  • Enhanced Swift support
  • Global namespace acceleration and L3 cache interaction
  • New node and SSD class compatibility support

In addition, the upgrade requirements for OneFS 7.2.1 differ from previous releases. This post highlights some of the new capabilities and upgrade requirements.

For more technical information about all of the new OneFS 7.2.1 features and enhancements, refer to the following documents:

New features

The following new features are included in OneFS 7.2.1.

Hardened profiles: Security Technical Implementation Guide (STIG)

If your site requires compliance with the Defense Information Systems Agency (DISA) STIG configuration standards, you’re in luck! OneFS 7.2.1 introduces a license-based security hardening feature through which you can apply and revert a hardening policy on the EMC Isilon cluster to meet DISA STIG configuration standards.

Networking:  enhanced IPv6 support

You can configure your cluster to accept client connections through both IPv4 and IPv6. OneFS adds dual-stack support to enable your cluster to support IPv4 and IPv6 client connections concurrently. And, OneFS 7.2.1 also supports IPv6-only environments.

Note that HDFS, InsightIQ 3.1 and earlier, MMC, NIS, and Swift are not supported over IPv6.

OneFS API: enhanced Swift support

Isilon Swift is now supported with the HTTP and secure HTTP (HTTPS) protocols over IPv4.

Isilon Swift supports the HTTP protocol with IPv6, but does not support HTTPS with IPv6. Isilon Swift also supports the HTTP protocol with IPv4 if STIG hardening is disabled.

File system: Global namespace acceleration (GNA) and L3 cache interaction

OneFS 7.2.1 includes some changes to how storage space calculations work when GNA and L3 cache are both enabled in the same cluster.

In OneFS, you can use solid-state drives (SSDs) for strategies such as GNA mirroring or for L3 cache. GNA mirroring enables data on node pools that do not have SSDs to have additional metadata mirrors on SSDs elsewhere in the cluster. The additional SSD metadata mirroring can improve file system performance by accelerating metadata read operations.

In OneFS 7.2.1, GNA requires that at least 20 percent of the nodes in the cluster contain at least one SSD, and that at least 1.5 percent of the total cluster storage is SSD-based. Any SSDs that are used for L3 cache are not counted against the GNA requirements: with GNA enabled and with L3 cache configured for a pool, the nodes in the pool with L3 cache configured become invisible to the GNA calculations. This change helps to ensure equitable and fair calculations when L3 cache and GNA are enabled in the same cluster.  For more information, see the OneFS 7.2.1 Release Notes and the OneFS 7.2.1 CLI Administration Guide.

Hardware: Node class compatibility

You can deploy a newer-generation node to a cluster that contains nodes from an earlier generation of the same class. For example, if your cluster already has a node pool that consists of Isilon X200 nodes, you can define a compatibility that enables you to add an X210 node to the same node pool. OneFS 7.2.1 supports compatibilities for S200/S210, X200/X210, X400/X410, and NL400/NL410 nodes. Compatible node generations must have identical HDD and SSD layouts and must have a compatible memory configuration. See the OneFS 7.2.1 Release Notes for details.

SSD compatibility

SSD compatibility enables you to add nodes with different capacity SSDs to the same node pool. For example, if your cluster has a node pool that consists of Isilon S200 nodes with 100 GB SSDs and you purchase new S200 nodes with 200 GB SSDs, you can create an SSD compatibility so that the new S200 nodes can be provisioned into the existing S200 node pool. For nodes of different generations—for example, S200 and S210 nodes – you might have to create a node class compatibility and an SSD compatibility to enable the S210 nodes to be provisioned into an S200 node pool.

Support for new platforms

OneFS 7.2.1 provides support for two new platforms: the X210 and the NL410. These nodes support node class compatibility. X210 nodes can be added to existing X200 node pools, and NL410 nodes can be added to existing NL400 node pools.

How to upgrade to OneFS 7.2.1

You can upgrade directly to OneFS 7.2.1 only from OneFS or later, or from OneFS or later. For more information, see Upgrade Paths to OneFS

If you want to upgrade to this new release, explore your upgrade options by reviewing the Isilon Supportability and Compatibility GuideThen, prepare for the upgrade process by reviewing the following documents:
