Release Notes for the Cisco NSS4000 and
NSS6000 Series, Version 1.16

November, 2009

These release notes contain important information about the Version 1.16 release
of the NSS4000/NSS4100 and NSS6000/NSS6100 Network Storage Systems
and any limitations, restrictions, and caveats that apply to these products.

Compatibility

This information is in the release notes:

• Compatibility

• Downloading and Upgrading the Firmware

• Open Caveats

• Closed Caveats

When the NSS is joined to the Windows Server 2008 domain and multiple users
are sharing the same file, these are the compatibility issues that can occur:

• When accessing a database file (such as a Microsoft Access file), files

opened by the user automatically obtain an exclusive lock, blocking other
users from opening the files, even in read-only mode.

• In other applications, when multiple users access the same file, each user

has read-write access privileges. This can cause the file to be overwritten
and can lead to data loss. If this occurs, no user warning message appears.

Release Notes

Although this feature is working, Cisco does not fully support joining the NSS to
the Windows Active Directory Server (ADS) in a Windows Server 2008
environment. This workaround only applies to a single user. (CSCsw93385)

Downloading and Upgrading the Firmware

This procedure describes how to upgrade the firmware on the NSS by using the
NSS Configuration graphical user interface (GUI).

NOTE Back up the system configuration file to a USB flash device and/or a RAID volume

by using the Configuration GUI before you upgrade the firmware. From the
Manager Menu, click Admin

To download and upgrade the NSS firmware:

STEP 1 Download the latest image from the Cisco support website to your local computer.

See http://www.cisco.com/support/index.shtml for further details. After
downloading, do not unzip the file.

Configuration to backup the file.

Base Model Firmware

NSS4000 NSS4000_fwupgrade_0116.tar.gz
NSS6000 NSS6000_fwupgrade_0116.tar.gz

STEP 2 Log into the Configuration GUI.

STEP 3 From the Manager Menu, click Admin Maintenance.

STEP 4 Click the Browse button and navigate to the

NSSxxxx_fwupgrade_0116.tar.gz

firmware upgrade image.

STEP 5 Click the Upgrade Firmware button.

STEP 6 Run this procedure again by repeating Steps 2 though 5.

Performing the upgrade twice allows the system to continue to operate properly
(when running the latest firmware), if a system failure occurs.

NOTE If you are moving drives between two NSS systems, make sure that both of the

systems are using the latest firmware and that the system configurations are saved
on USB memory sticks and/or a RAID volume.

• When upgrading the firmware from v1.12 to v1.14 or v1.12 to v1.16, the

Configuration GUI displays a "Programming images.." message for more
than 12 minutes (the time it takes to upgrade the firmware is usually 5 to 10
minutes).

Release Notes

The workaround is to wait at least 15 minutes to complete the upgrade and
then power cycle the NSS by removing the power cord. Do not try and
access the Configuration GUI during this time. (CSCsx17923)

• When the NSS is joined to an ADS domain and you upgrade the firmware,

the ADS is unable to access a share.

The workaround is to rejoin the NSS to the ADS domain. (CSCsw94409)

Open Caveats

For more information about upgrading the firmware, see the

Administration Guide

These are the open caveats for this release. These caveats apply to both the
NSS4000 and NSS6000 unless otherwise specified.

• CSCsw86058

When the NSS is running over a network that is on a different subnet, a user
cannot mount a CIFS connection by using a hostname.

The workaround is to mount the CIFS connection by using an IP address.

• CSCsw86138

When an unexpected power cycle occurs on the NSS, the time might be
corrupted on the NSS. This only applies if the time is set manually, not by
using NTP.

When this occurs, a pop-up alert window appears when you access
Configuration GUI after the unexpected shutdown.

available on Cisco.com.

NSS4000/NSS6000

The workaround is to manually check the time in the GUI. From the Manager
Menu, click Admin

• CSCsw86187

If a data write operation is in progress, and the system power is interrupted,
data stored in a degraded RAID1 or RAID5 array might become
inaccessible. This is common to all NSS systems using software RAID
implementations.

These are the workarounds:

- Replace the failed drives in the degraded arrays as soon as possible, as

Time and correct the time if necessary.

failed RAID arrays can result in complete loss of all user data.
