Introduction

This document describes important product information and restrictions for the Dell PowerVault NX3600/NX3610 NAS

appliances, Dell Fluid File System (FluidFS) version 2.0, and the NAS Initial Deployment Utility (IDU).

What's New In the System

Introduction Of The Dell PowerVault NX3600 And NX3610 Appliances

FluidFS version 2.0 introduces the next generation of hardware platforms for NAS:

• The NX3600 appliance containing two 1 Gb NAS controllers

• The NX3610 appliance containing two 10 Gb NAS controllers

The NX3600/NX3610 appliances contain two highly available active/active NAS controllers in a single 2U chassis. The

NX3600/NX3610 appliances are also easy to deploy as they have integrated Backup Power Supplies (BPS) and require

fewer network connections than the NX3500. An NX3610 cluster can contain up to two NAS appliances or four active

NAS controllers in a single namespace. With built-in client load balancing, all controllers actively serve data, thus

maximizing resource utilization and hence performance. With redundant hardware components and a clustered file

system architecture, the NAS appliances are built for high availability. In a NAS cluster, any single controller can fail

without affecting data availability or causing data loss. A controller failure causes the peer controller in the same

appliance to take over the failed controller.

Introduction Of The NAS Initial Deployment Utility

The NAS IDU is a Windows-based application that performs initial configuration for the NX3600/NX3610 appliances.

When installed on a Windows-based computer that is connected to the same network as a NX3600/NX3610 appliance,

the NAS IDU uses non-routable IPv6 unicast traffic to discover the appliance. After discovery is complete, the NAS IDU

allows you to assign IP addresses to the appliance and create a cluster from the available controllers.

Known Issues And Limitations

Fluid FS Version 2.0

LDAP Requires Anonymous Access

Description FluidFS currently does not support non-anonymous LDAP. If you try to connect to your cluster

with a non-anonymous LDAP account, the following message related to client connection

rebalance is erroneously displayed:

Client connection rebalance across available NAS nodes

succeeded. Not all NAS nodes are available at this time.

Workaround/

Solution

Use anonymous LDAP user credentials to connect to your cluster.

The Console Displays An Inaccurate (Failed) Message When The Controller Is In Standby Mode

Description When the controller is in standby mode, the following message is displayed on the console:

Press: 'i' - re-Install standby controller[FAILED]

This messages indicates that the controller is in standby mode.

Workaround/

Solution

Ignore this status message, this message is not displayed after clusterization is complete.

Cannot Rename NAS Volume That Is Part Of A Replication

Description The system does not allow renaming of NAS volumes that are a part of a replication

partnership.

Workaround/

Solution

Do not rename a NAS volume that is a part of a replication partnership.

Add Pair Via NAS Manager Can Not Be Restarted If The Add Pair Operation Fails To Attach Members Due

To IP Address Conflict

Description You cannot restart the add pair operation using the NAS Manager , if the add pair operation

fails due to an IP address conflict.

Workaround/

Solution

Contact Dell support.

Replication Status Fails After Detach Operation Is Run From The Source Cluster.

Description Detaching a node from the source cluster during active replication operation may cause

replication to fail.

Workaround/

Solution

Retry the replication after the node is detached successfully.

No Message Is Displayed When Deleting A Replication Partnership From The Destination Cluster

Description When deleting a replication partnership from the destination cluster, FluidFS does not prompt

you to apply the volume configuration.

Workaround/

Solution

You must manually apply the volume configuration on the destination cluster.

Interrupted System Call Warning Message Repeatedly Logged In Syslog

Description The warning message Error in payload recv_n errno 4 Interrupted

system call is repeatedly logged in the Syslog.

Workaround/

Solution

This warning message can be safely ignored.

Progress Bar In Microsoft Internet Explorer Version 8 Remains at 99% Completion When Applying Service

Pack Upgrade

Description When you apply a service pack upgrade using Microsoft Internet Explorer version 8, the

progress bar remains at 99% completion after the service pack is applied successfully.

Workaround/

Solution

Follow any of the workarounds to resolve the issue:

• Before upgrading the service pack, update the Microsoft Internet Explorer to version 9.

• Use any web browser other than Microsoft Internet Explorer version 8 to apply the

service pack upgrade.

• Use the Command Line Interface to apply the service pack upgrade.

NAS Initial Deployment Utility

Host Discovery Fails For Hosts With More Than One IP/Subnet

Description Running the NAS IDU on hosts with more than one IP/subnet causes host discovery failures.

Workaround/

Solution

Ensure that the system running the NAS IDU is connected to only one subnet.

Clusterization Fails If Broadcast And Network IP Addresses Are Entered In Host Address Fields

Description NAS IDU incorrectly accepts broadcast and network IP addresses in host address fields.

Clusterization fails if broadcast or network IP addresses are entered in the host address fields.

Workaround/

Solution

Ensure that you do not enter broadcast or network IP addresses in the host address fields.

Clusterization Fails If There Are IP Address Conflicts

Description NAS IDU does not check for IP address conflicts on the network. Clusterization fails if IP

address conflicts exist.

Workaround/

Solution

After entering all the IP addresses, on the Summary screen, check the list of IP addresses to

ensure that there are no IP address conflicts with your network environment.

NAS IDU Does Not Automatically Or Manually Discover The NAS Appliance(s)

Description NAS IDU fails to discover the NAS appliance(s) both automatically and manually.

Workaround/

Solution

Connect the system running the NAS IDU to the same switch as the FluidFS NAS appliance(s).

IP Addresses For Two MD Arrays Required Even When Only When MD Array Is Connected

NOTE: This issue is applicable only to the NX3610 NAS appliance.

Description The NAS IDU requires IP addresses for two MD arrays even if only one MD array is connected.

Workaround/

Solution

You must enter the IP address of the single MD array in both fields.
