You can use any SSH client such as OpenSSH or PuTTY to connect to an EMC Isilon cluster.
Before you begin
You must have valid OneFS credentials to log in to a cluster after the connection is open. Procedure
1. Open a secure shell (SSH) connection to any node in the cluster, using the IP address of the node and port number 22.
2. Log in with your OneFS credentials.
At the OneFS command line prompt, you can use isi commands to monitor and manage your cluster.
Licensing
Advanced cluster features are available when you activate licenses for OneFS software modules. Each optional OneFS software module requires you to activate a separate license.
For more information about the following optional software modules, contact your EMC Isilon sales representative.

l InsightIQ l Isilon for vCenter l SmartConnect Advanced l SmartDedupe l SmartLock l SmartPools l SmartQuotas l SnapshotIQ l SyncIQ
License status
The status of a OneFS module license indicates whether the functionality provided by a module is available on the cluster.
Licenses exist in one of the following states: Status Description
Inactive The license has not been activated on the cluster. You cannot access the features provided by the corresponding module.
Evaluation The license has been temporarily activated on the cluster. You can access the features provided by the corresponding module for a limited period of time. After the license expires, the features become unavailable unless the license is reactivated. Activated The license has been activated on the cluster. You can access the features provided
by the corresponding module.
Expired The evaluation license has expired on the cluster. You can no longer access the features provided by the corresponding module. The features will remain unavailable unless you reactivate the license.
The following table describes what functionality is available for each license depending on the license's status:

Activated Expired
HDFS Clients cannot access the cluster through HDFS.
You can configure HDFS settings and clients can access the cluster through HDFS.
You cannot configure HDFS settings. After the HDFS service restarts, clients can no longer access the cluster through HDFS.
InsightIQ You cannot monitor the cluster with InsightIQ.
You can monitor the cluster with InsightIQ.
InsightIQ stops monitoring the cluster. Data previously collected by InsightIQ is still available on the InsightIQ instance.

that are stored on an Isilon cluster.
SmartPools All files belong to the default file pool and are governed by the default file pool policy. Virtual hot spare allocation, which reserves space for data repair if a drive fails, is also available.
You can create multiple file pools and file pool policies. You can also manage spillover, which defines how write operations are handled when a storage pool is not writable.
You can no longer manage file pool policies, and the SmartPools job will no longer run. Newly added files will be governed by the default file pool policy, and the SetProtectPlus job will eventually apply the default file pool policy to all files in the cluster.
If the SmartPools job is running when the license expires, the job completes before becoming disabled. SmartConnect
Advanced
Client connections are balanced by using a round robin policy. IP address allocation is static. Each external network subnet can be assigned only one IP address pool.
You can access features such as CPU utilization,
connection counting, and client
connection policies in addition to the round robin policy. You can also configure address pools to support multiple DNS zones within a single subnet, and support IP failover.
You can no longer specify SmartConnect Advanced settings.
SmartDedupe You cannot deduplicate data with SmartDedupe.
You can deduplicate data with
SmartDedupe.
You can no longer
deduplicate data. Previously deduplicated data remains deduplicated.
SmartLock You cannot enforce file retention with SmartLock.
You can enforce file retention with SmartLock.
You cannot create new SmartLock directories or modify SmartLock directory configuration settings for existing directories. You can still commit files to a write once read many (WORM) state, even after the SmartLock license is unconfigured, but you cannot delete WORM- committed files from enterprise directories.

SnapshotIQ You can view and manage snapshots generated by OneFS applications. However, you cannot create snapshots or configure
SnapshotIQ settings.
You can create, view, and manage snapshots. You can also configure snapshot settings.
You will no longer be able to generate snapshots. Existing snapshot schedules are not deleted; however, the schedules will not generate snapshots. You can still delete snapshots and access snapshot data. SmartQuotas You cannot create
quotas with SmartQuotas.
You can create quotas with SmartQuotas.
OneFS disables all quotas. Exceeding advisory and soft thresholds does not trigger events. Hard and soft thresholds are not enforced. SyncIQ You cannot replicate
data with SyncIQ.
You can replicate data with SyncIQ
You will no longer be able to replicate data to remote clusters, and remote clusters will not be able to replicate data to the local cluster. Replication policies will still display a status of enabled; however, future replication jobs created by the policy will fail. If a replication job is in progress when the license expires, the job completes.
