Cannot fully install Secure Path Manager
When attempting to install Secure Path Manager, the install fails.
The Client Tools displays a Java Runtime Engine
install. ‘Windows cannot find JREs\j2re-
1_3_1-win.exe message. To resolve this issue, after
installation of Secure Path Manager and BEFORE running Client
Tools to install the Java Runtime Engine, exit the installation
tool (Automenu.exe) and re-run it. During the second run of the
installation tool, the client tools \JRE install will function
correctly.
Shadow Copy for Shared folders is the wrong version
The code installed in the image under
C:\hpnas\Components\ShadowCopyClient\XP and
2000-SP3+ is an older version of the client code. This version
contains a bug for Windows 2000 clients where the previous
versions of deleted files and folders are not displayed at the share
point. Download the latest version of the client piece as
documented in the administration guide.
Services for NFS
NFS performance will increase when changing from the default
of synchronous writes to asynchronous writes.
To change from synchronous to asynchronous writes (and vise
versa), open the Web UI and click Shares, Sharing Protocols,
choose the NFS Protocol, and click Properties. Click the NFS
Async/Sync Setting button to toggle between asynchronous and
synchronous writes.
NOTE:After toggling between synchronous and asynchronous writes (and
vise versa), the NFS server service must be restarted. Inform all users before
restarting the service.

Keep the following in mind when toggling between synchronous
and asynchronous writes:
1. When the caching setting for Services for NFS is set to
asynchronous writes (caching on), NFS clients may
incorrectly assume that all the writes were safely committed
to stable storage; the writes were only in the Server for NFS
cache.
2. For asynchronous writes: although Server for NFS informs
the NFS client that the data has been safely written to disk,
the data is still stored in cache and is waiting to be written to
disk. This could cause file corruption issues if, for example,
you lose your power supply to the Server for NFS server
while data is still in the cache. At this point, the NFS client
assumes that data that was lost was actually safely written to
disk.
3. With synchronous writes on (caching off), all write requests
are immediately committed to disk before a response is sent.
Although synchronous writes “on” does frequently slow
NFS file writes, it does improve the stability and data
integrity.
WARNING: Turn asynchronous writes on only if you are willing
to risk file corruption if any issue with the Services for NFS server
causes the cache to be lost (for example, if the system shuts down,
stops responding, loses its power supply, or experiences other
serious issues).
Comments in Password and Group file not recognized
Comments preceded by a “#” in the Password and Group file
will not be recognized when specifying the Password and Group
file for setting up the User and Group mappings of the NFS
protocol. If a Password or Group file is used with a comment,
the following error will be displayed in the WebUI: The user
list cannot be retrieved. Make sure the
password file is not corrupted and then try
again.

Clearing the NFS log via the WebUI causes the log file to
become inaccessible
When clearing the NFS logs via the WebUI, the log file will
clear but the file permissions are set incorrectly. Access to the
log c:\msnfs\logs with Windows Explorer will be denied.
To resolve the issue, stop the Server for NFS service, then clear
the NFS log, then start the Server for NFS service. The log file
will then be accessible.
NFS administrative shares support
Services for NFS does not work with administrative shares in the
same fashion as CIFS. By default, a volume drive such as C: is
CIFS shared as C$. This is an example of an administrative share
and is hidden to CIFS clients. If an NFS share is created and
named drive S, as in the example, the share will not be hidden to
NFS clients. This NFS share will act as a normal NFS share.
Volume Mount Points support
Attempting to create an NFS share on a disk mounted on a
mount point will result in the error:
Cannot write IOCTL to NFS driver….
HP StorageWorks NAS 4000s/9000s supports many network
sharing protocols including the NFS protocol for UNIX and
Linux clients. Shares for which the NFS protocol will be enabled
must be created on logical disks that are mounted on a drive
letter. Microsoft Windows Storage Server 2003 supports
mounting virtual disks onto mount points or reparse points
created on another disk already mounted on a drive letter.
Mount points enable the administrator to mount many disk
devices under a single drive letter, creating the appearance and
behavior of a larger disk drive with a contiguous namespace.
However, the Microsoft Services for NFS Server does not yet
support the functionality of mount points.

All logical disks to be used for NFS sharing should be mounted
on a drive letter, not on a reparse or mount point. If no NFS
shares will be created on a particular logical disk, that virtual
disk may be mounted on a mount point instead of a drive letter.
Admin cannot list and map domain users and groups for
Services for NSF mapping unless the Services for NFS
admin is logged into the domain
The administrator must log into the domain before mapping
domain users and groups. If the admin is not logged into the
domain, the domain user or group is not displayed on the list of
Windows users or groups and thus cannot be mapped.
User name mapping Japanese characters
User name mapping for the network file system (NFS) server
does not support Windows or UNIX user names containing
Japanese characters.
The names of NFS client groups that are used by the NFS server
cannot contain Japanese characters.
Mapping service fails to start
All network ports must be attached to an active link or contain a
port terminator, or the user mapping service will fail to start on
boot. In conjunction with this failure, an error event ID 7034 is
logged in system log with details as followed:
Source: Service Control Manager
Category: none
eventID : 7034
file name: netevent.dll
Description: the user name mapping service terminated
unexpectedly.

The mapping service can be re-started once all network ports
become active through a link or port terminator.
Help instructions for creating NFS share cluster resource is
incorrect
The help instructions for the WSS2003 Services for NFS share
cluster resource creation lists an incorrect parameter. The
GlobalPerm parameter should be documented as GlobalPermV2
instead.
NAS Web User Interface
Rapid Startup Wizard automatically advances
If no changes are made to the Date and Time Settings page of the
Rapid Startup Wizard, the page will automatically advance to the
next page of the Rapid Startup Wizard after one minute. This
occurs to retain the appropriate time on the system.
List boxes do not scroll properly
Some versions of Internet Explorer will fail to scroll through list
boxes that are scrolled out of view from the browser window and
then scrolled back into view. If this occurs, simply maximize the
browser window so that the entire list box is displayed.
Cluster Resource Shares appear in share pages of Web UI
On the share pages of the Web UI, cluster share resources will
appear and actions may be taken against them. The actions will
appear to complete but in actuality will fail. The cluster
administrator is the proper tool for managing cluster resource
shares.

Advanced Cluster Management button yields error on non-
configured clusters
On a system where clustering is not established, clicking on the
Advanced Cluster Management button will yield an error from
cluster administrator that Cluster service on node
xxxx cannot be started. The Service is
either not installed or not configured. This
message is displayed when attempting to setup the cluster for the
first time and is considered normal. Closing the message and
selecting File > New > Cluster will resolve the issue.
Rapid Startup will not alter the Administrative Password
The Rapid Startup Wizard will fail to alter the Administrative
password if the NAS device does not have an active network
connection. To resolve the issue establish a network connection
and restart the wizard.
Cluster Create Resource Wizard does not save state
When utilizing the Web UI to create cluster resources, some of
the wizard pages do not save the current data held in the fields if
the page is revisited by pressing the back button. Upon revisiting
the page the data will require reentry of the information.

Improper Closure of Remote Desktop
Certain operations can leave the utilities running if the browser is closed
versus exiting from the program via the application menu or logging off
the terminal server session. Some applications may become orphaned in
this manner when the Terminal Server Session is exited improperly. Note
that a maximum of two Terminal Server sessions may be used at any
given time. Improper exit from a session can result in both sessions
becoming consumed, possibly resulting in a temporary inability to launch
a Terminal Server or Remote Desktop session Eventually, the orphaned
sessions will be terminated automatically, or these Sessions and
processes may be terminated via the Terminal Services Manager
viaStart > Programs > Administrator Tools.
Configuring NIC Teaming through Remote Desktop results
in failure of NIC Teaming
When configuring NIC Teaming through Remote Desktop, if the
port being used for access is a part of the NIC Team, NIC
Teaming may not install correctly and access to the port may be
terminated. HP recommends using either Insight Lights-Out port
or local console access when setting up the 4000s/9000s for NIC
Teaming.
Disabled network cards not visible in Web UI
If a network card is disabled, the network card will not appear in
the Web UI. Remote Desktop must be used to re-enable the
network card before it will be visible again in the Web UI.

Rapid Startup becomes unresponsive if a NIC team is
established
Rapid Startup becomes unresponsive, if a NIC Team is
established and then Rapid Startup is run with the team in place,
the network settings pages will become unresponsive, and the
wizard page cannot be exited. To exit Rapid Startup, click some
other menu item in the Web UI.
NOTE: NIC Teams will need to be dissolved when utilizing Rapid Startup.
Renaming host does not change address bar of browser
When renaming the host from the Web UI, the server will restart
but the address bar identification is not altered. The Web UI may
continue to function but may result in a message:
The page cannot be displayed.
or a Remote Desktop script error. To correct the issue, type the
new name of the server into the address bar.
Renaming host forces a restart where the restart page does
not refresh
When renaming the host in Rapid Startup, the restart page does
not refresh to the Welcome page. To resolve the issue, retype the
new host name in the address bar on port 3202.

Altering the Network interface from DHCP to static causes
the page not to return
If the Web UI is used to alter the IP settings of the port from
which you are managing, the host will be unreachable from the
current address. When this happens, the network interface page
buttons become grayed out and the page does not return,
although the settings take affect. To access the Web UI again,
close and open the browser and navigate to the newly identified
management port.
Managing NTFS Mount points
There is currently no facility for managing NTFS mount points
in the Web UI. To create or manage NTFS mount points, you
must use Remote Desktop. To start Remote Desktop, select
Maintenance, then Remote Desktop on the navigation menu.
Default Username and Passwords
The default username and password for administration of the
server either through the Web UI or the console is:
Username: Administrator
Password: hpinvent
The default username and password for the systems management
and ACU pages of the device are:
Username: administrator
Password: administrator
Web UI continues to display orphaned shares
In Windows Storage Server 2003, deleting a disk that contains a
share leaves an orphaned share on the file system. Orphaned
shares will continue to be displayed in the Web UI until removed
or until the system or service is restarted.

DFS root does not update on file share page
If a DFS root is created and enabled by default on shares, then
later recreated under a new name, the File Share page does not
update the DFS local root information and attempts to create
DFS entries under the old name. To correct this issue, access the
Distributed File System Properties page, update the default DFS
information, and click OK. The file share page will now contain
the proper DFS information.
FAT & FAT32 volumes are not displayed on the volumes
main page
Since the Disks >Volumes main page of the Web UI can only
manage NTFS volumes, the page only displays NTFS volumes.
HTTP Access is denied even though protocol is listed as
running
In the Shares> Sharing Protocols page of the Web UI, the
HTTP protocol may be listed as Running and Automatic, even
though the security settings disable access. To resolve the issue,
select Shares > Sharing Protocols > Select HTTP > Properties
> Security from the Web UI. Set the appropriate level of
security to enable access.

Cannot add a new node into existing cluster from new
node
In a cluster already up and running, if an attempt is made to add
a new node from the server which is not a existing member, the
action will fail and a message will be displayed The cluster
service on new node can not be started. The
only way to add new node in a cluster is to add it from a node
that is already a member of the cluster.
Cluster reference fails when using the cluster name to
access cluster administrator on the local node
When using cluster administrator to administer the local cluster,
the use of the cluster name will fail to access the cluster. Use of
the “.” is an acceptable workaround in the connect field of
cluster administrator. Alternatively, one may use any node
member’s host name to connect to the cluster through cluster
administrator.
Cluster node eviction occasionally fails
When attempting the eviction of a cluster node, intermittent
failures can occur in the eviction process and the cluster will
report the node evicted. However, the node being evicted will
retain its cluster information and reformation of the node into the
cluster is blocked. This is especially true when the node being
evicted was turned off when the eviction process occurred. In
these circumstances, a forced cleanup of the node is required via
the following command line procedure prior to the reforming of
the cluster:
cluster node nodename /forcecleanup
On occasion this command will fail also and a registry entry is
required for the cluster cleanup. To create a place holder, type
the following line at the command line:
sc create clussvc

Incorrect error when file screening is implemented under
Storage Manager
If file screening is enabled on a volume or directory for a
particular file type and a file transfer of the restricted type is
attempted to that volume, an inappropriate error message is
returned to the user. The user receives a Not enough free
disk space error message when disk space is indeed
available, the file is simply blocked.
Cannot connect to AppleShare from a MacIntosh machine
Using a Mac OS X machine when accessing a NAS share returns
an error indicating:
No file services are available at the URL
afp://IPaddress. Try again later or try a
different URL (server returned error-5002).
If the client authentication method is set to MS + Appletalk,
clear text on the client the operation will succeed.
DFS Local Root Cluster support
DFS Local Root support in a cluster is fully supported. The
presence of the root as a clustered resource provides fault
tolerance for the name space. To establish a clustered DFS root,
a physical disk resource, IP address, network name and file
share which is DFS Root enabled is required. Once the root is
created, it can be managed in the Distributed File System Tool
available in the Windows 2003 Desktop GUI via the remote
desktop tool.
DFS link components can exist in the local cluster or across
NAS devices. In the case of links referring to clustered file share
resources, each share must have an associated network name, ip
address and underlying physical disk resource.
