Compatibility

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.

2 Release Notes for the NSS2000 Series Firmware Version 1.16

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 Configuration to backup the file.

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.

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 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

These are the open caveats for this release.

•CSCsv34635

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.

•CSCsv34808

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.

The workaround is to manually check the time in the GUI. From the Manager

Menu, click Admin Time and correct the time if necessary.

•CSCsv34900

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

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

-Use the degraded mode management feature to limit the amount of time

that a RAID array will run in the degraded state.

-Implement a backup power strategy by using a UPS or RPSU backup

power system.

4 Release Notes for the NSS2000 Series Firmware Version 1.16

Release Notes

•CSCsv34917

When rebuilding a RAID1 spare device, the rebuilding does not resume

after the NSS reboots. After reboot, the array might be falsely marked as

clean and the drive falsely marked as synced. This does not affect the

initial rebuild of an array following a RAID creation.

The workaround is to not reboot the NSS during the RAID rebuild.

•CSCsv34936

If power is interrupted when rebuilding a RAID array (RAID1, RAID5 or

RAID10), the rebuild does not restart automatically after the system is

powered up again.

When this occurs, the array remains in the degraded state and the rebuilt

drive is ejected from the array.

The workaround is to manually restart the rebuild by adding the ejected

drive back to the array by using the Configuration GUI.

•CSCsv46267

When the RAID global spares option is enabled in the Configuration GUI,

the RAID spares are not shared during the RAID array rebuild.

For example: If RAIDA has a hot spare and RAIDB does not, if RAIDB is

degraded while RAIDA is rebuilding, the spare will not transfer to RAIDB

until after RAIDA completes the rebuild.

There is no workaround.

•CSCsv46961

When the Default Network Policy filter is set to Drop Traffic, no automatic

Allow Filter is created for the default gateway.

When this occurs, all traffic from the default gateway is dropped and all

traffic sent from other subnets through a router is not forwarded to the

NSS.

The workaround is to manually create an AllowAll Network Access Filter

for the default gateway IP address by using the Configuration GUI.

•CSCsv47134

When writing simultaneously to the same file by using NFS and FTP or by

using NFS and CIFS, the NSS file locking mechanism does not

work properly.

Release Notes for the NSS2000 Series Firmware Version 1.16 5

Release Notes

There is no workaround.

•CSCsv47151

When you create a share by using the Initial Setup wizard and enable NFS,

users are assigned root privilege access.

The workaround is to not enable NFS in the Initial Setup wizard. If NFS is

required, you can enable it at a later time by using the Configuration GUI.

•CSCsv47178

When the NSS sends out a broadcast message to discover an NIS server,

the broadcast is only sent to the physical interfaces, not over any VLANs

that are defined in the system.

The workaround is to not use the NSS in networks where NIS servers are

only accessible over VLANs.

•CSCta50061

If a user was granted write access to a share and the write access was

revoked, the user can still write to subfolders by using FTP and NFS.

This problem only occurs under these conditions:

-The user has write privileges to the subfolder (either because the user is

the owner, or was granted access by the owner).

-The user has read privileges to the share (by having explicit share read-

only access).

The workaround is to not enable FTP and NFS (which is disabled by

default), if these protocols not being used.

•CSCta87135

When using filenames with Chinese characters, characters are lost when

transferring the files to the NSS by using the FTP protocol.

The workaround is to use the CIFS protocol.

6 Release Notes for the NSS2000 Series Firmware Version 1.16

Release Notes

Closed Caveats

Resolved in Firmware Version 1.16

•CSCsv34671

When the Network Access Filter is set to Policy=Drop Traffic and

Filter=AllowAll or Policy=Drop and Filter=AllowCIFS, the CIFS mount

now works.

•CSCsv34675

When the Network Access Filter is set to Filter=AllowHTTPS and

Filter=DropFTPS, you can now add Network Access from the

Configuration GUI.

•CSCsv34906

When a RAID0 array failure occurs, an alert (SNMP trap, email or system

alert) is now triggered.

•CSCsv46326

When a Seagate 1 terabyte (TB) hard drive (model ST31000340AS) is

installed in the NSS, it is not detected by the system on bootup or when

hotplugging the drive.

There is no workaround. This drive is not compatible with the NSS2000.

For a current list of compatible disk drives, see the Cisco Approved Vendor

List for Network Storage Systems at: http://www.cisco.com/en/US/

products/ps9957/prod_technical_reference_list.html

•CSCsv46327

When Seagate hard drives are installed in the NSS, they are now

immediately detected on bootup.

•CSCsv46993

The maximum transmission unit (MTU) size of the NSS is now supported.

•CSCsv47120

If a user was granted write access to a share and the write access was

revoked, the user can no longer write to subfolders by using FTP.

Release Notes for the NSS2000 Series Firmware Version 1.16 7

Release Notes

•CSCsv47174

The Network Identification page in the Configuration GUI now accepts

domain controller hostnames that begin with a digit.

•CSCta87119

When running firmware V1.13.30 on the NSS, you cannot configure a share

folder to work with the Symantec BackupExec application.

This problem was fixed in firmware version 1.16.
