•General Notes

•Services for UNIX® (SFU)

•NAS Web User Interface

•Microsoft® Server 2003

General Notes

Compaq IML Log Viewer Win32App does not recognize

.iml files

If the Compaq Integrated Management Log Viewer is run from

the system desktop via

Start >Programs > Compaq System Tools >

Compaq

and the save log file option is utilized, the IML will not reopen

the file created and an error is displayed. The error displays:

You have attempted to open a file that is not

recognized by the viewer. Please try a

different file.

This issue will be resolved in SmartStart and Support Software

7.0.

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.

Writer: Ron Reisdorf File Name: 352398-001

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.

Codename: AMX Part Number: 352398-001 Last Saved On: 10/27/03 4:39 PM

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.
