Overview

These release notes are for the StorageWorksTM NAS Executor

E7000 by Compaq running version 2.0 of the NAS software

image. This document provides important information that is not

covered in other documentation.

IMPORTANT: Read this entire document before installing and

configuring the StorageWorks NAS Executor E7000.

Software Updates

The software that ships with the StorageWorks NAS Executor

E7000 includes a special build of Microsoft Windows-Powered

Operating System. Any software updates must be qualified

against the Windows-Powered Operating System.

IMPORTANT: Install only Compaq-approved patches or service packs.

To view the list of approved patches please see the

StorageWorks NAS Website at:

http://www.compaq.com/storage/nas_index.html.

NFS Logging

The maintenance of the NFS log through the web interface to the

E7000 does not allow the deletion of the log. The NFS log

delete option is located in the WebUI under Maintenance, Logs,

NFS Log, and then clicking the Clear button. After clicking the

Clear button, a confirmation screen appears. After clicking OK

to confirm the deletion, the following error message will appear:

"Error: There has been a sharing violation.

The source or destination file may be in use."

The administrator can delete the log after the Server for NFS

service is stopped.

Be aware that this will cause a service interruption to all users

trying to access NFS shares on the E7000.

1. Open the web user interface to the E7000.

2. Click Maintenance->Terminal Services and log in.

3. Right mouse click the My Computer icon and choose

Manage.

4. Open the Services portion of the management tree.

5. Select and stop the Server for NFS service.

You can now delete the log using the web interface as

instructed.

6. Start the Server for NFS service.

NFS administrative shares support

SFU 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 from CIFS clients. If an NFS share is created and

named drive$, as in the example, the share will not be hidden

from 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 message:

“Cannot write IOCTL to NFS driver…”.

StorageWorks NAS Executor E7000 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 Virtual Disks that are mounted on a

drive letter. Microsoft Windows-Powered OS 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 UNIX (SFU) NFS Server

does not yet support the functionality of mount points.

All virtual 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 virtual disk, that virtual

disk can be mounted on a mount point instead of a drive letter.

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 name of NFS client groups that are used by the NFS

server cannot contain Japanese characters.

NFS Share parameters cannot be changed after

taking a group offline

NFS Share parameters cannot be changed after taking its group

offline. An error will appear when attempting to edit the NFS

parameters in this manner.

"Error: The Path entered does not exist."

Workaround:

NFS Share parameters can be modified if the NFS resource is

taken offline individually, rather than as a group.

Take only the NFS share that you want to edit offline and then

change parameters.

1. Select Cluster Management from the WebUI.

2. Click Resources.

3. Click the radio button for the NFS resource being edited.

4. Click Take Offline.

5. Return to the Resources page and click the radio button for

the NFS resource being edited.

6. Click Parameters from the NFS resource properties page.

7. Edit the parameters and click OK.

8. Using Cluster Management in the WebUI, turn the NFS

resource to online.

Admin cannot list and map domain users and

groups for SFU mapping unless the SFU admin

is logged into the domain

The administator 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.

Password Synchronization will not work

correctly on a Domain Controller without an

Admin UI

The sfucustom.msi file located on the StorageWorks NAS E7000

at c:\SFU does not install an Admin UI for password

synchronization on a DC.

The Admin UI is used to set up:

•=Direction of password synchronization

NOTE: NFS Authentication Tools and Password Synchronization can

be installed separately or together. The instructions follow.

To install Password Synchronization on the DC by itself (no

NFS Authentication Tools):

1. Allow the c:\WINNT\bin\SFU directory of the E7000 to be

shared.

net share SFU=C:\WINNT\bin\SFU

2. On the DC, connect to the share.

net use Z: \\NAS_machine_name\SFU

3. Change directories from the DC to the root of the connected

E7000 share.

cd /d Z:\

4. Run the install program on the DC.

OemSetup.msi ADDLOCAL=PasswdSync

SFUDIR=C:\SFU OEMINSTALL=TRUE SOURCELIST=Z:\

/l*v %temp%\sfusetup.log /q

5. Reboot the DC.

The DC must be rebooted manually after installing the password

synchronization piece to run correctly.

6. Run the Admin UI on the DC and setup password

To install NFS Authentication Tools on the DC by itself (no Password

Synchronization),Use the instructions outlined in the E7000

Administration Guide.

To install NFS Authentication Tools and Password

Synchronization on the DC:

1. Allow the c:\WINNT\bin\SFU directory of the E7000 to be

shared.

net share SFU=C:\WINNT\bin\SFU

2. On the DC, connect to the share.

net use Z: \\NAS_machine_name\SFU

3. Change directories from the DC to the root of the connected

E7000 share.

cd /d Z:\

4. Run the install programs on the DC in the following order.

a. OemSetup.msi ADDLOCAL=NFSServerAuth

SFUDIR=c:\SFU OEMINSTALL=TRUE

SOURCELIST=Z:\ /l*v %temp%\sfusetup.log /q

b. OemSetup.msi ADDLOCAL=PasswdSync

SFUDIR=c:\SFU OEMINSTALL=TRUE

SOURCELIST=Z:\ /l*v %temp%\sfusetup.log /q

5. Reboot the DC. The DC must be rebooted manually after

installing the password synchronization piece to run

correctly.

Disconnected Client Telnet Session can cause

the SFU GUI to hang

If a client Telnet session is forcibly disconnected from the E7000

while the SFU GUI is open, the SFU GUI can hang and become

unusable. To get around this, stop the SFU GUI on the E7000

using Task Manager and reopen the SFU GUI.
