Release Notes Information
These Release Notes cover the following major topics:
•Japanese Support for the 1200s
•Services for NFS
•NAS Web User Interface
•Microsoft Storage Server 2003
•Quick Restore Process
Japanese Support for the 1200s
The NAS 1200s supports Japanese, but a conversion process
must be competed before running Rapid Startup. To convert the
1200s into Japanese:
1. Connect a keyboard, monitor, and mouse.
2. Login to the local console using the Administrator account.
The password is ”hpinvent”.
3. Select Run from the Start menu.
4. Enter the following:
c:\hpnas\Conv.vbs
5. Select Yes to convert the system to Japanese and restart the
server.

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 are only in the Services 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 might 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 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).
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, 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 driveS, 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 1200s 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 NFS
mapping unless the NFS admin is logged into the domain
The admin 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 on the list of Windows users or
groups and cannot be mapped.
User name mapping Japanese characters
User name mapping for the network file system (NFS) server
does not support UNIX user names containing Japanese
characters.
The names of NFS client groups that are used by the NFS server
cannot contain Japanese characters.

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”.
Mapping Service Fails to Start
If all network ports are not attached to an active link or contain a
port terminator, the 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.

NAS Web User Interface
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 Remote Desktop session. Some applications
may become orphaned in this manner when the Remote Desktop
Session is exited improperly. Note a maximum of two Remote
Desktop sessions may be used at any given time. Improper exit
from a session can result in the sessions becoming consumed.
Sessions and processes may be terminated via the Terminal
Services Manager via Start > Programs > Administrative
Tools.
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 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.
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 Terminal Services script error. To correct the issue, type the
new name of the server into the address bar.
