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.

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.
