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.

"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.

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:

The first 16 digits refer to the WWN number of then SAN
that the LUN resides. The last 16 digits refer to the unique
LUN ID for that particular LUN. This number can be used to
track the LUN back to the SAN. First track the WWN of the
SAN. (First 16 digits if the UUID number) Keep in mind
that all SANs have a unique WWN number and that the
number will begin with a 6000. For example, the UUID is
6000 1fe1 0008 2260 0009 0300 4924 0124. The WWN for
the SAN correlates to the first 16 digits of the UUID, or
6000 1fe1 0008 2260. However, you need to change the
6000 to a 5000 so the WWN that you are looking for is 5000
1fe1 0008 2260. The final step will isolate the LUN within
the SAN, making the search simpler.

SAN Connection Process
The process of configuring the StorageWorks NAS E7000 with
the correct software for a particular SAN configuration is
accomplished via a WEB interface and an automated installation
process. This automated process and interface do not yet account
for updates or changes to the SAN configuration after the initial
setup.
IMPORTANT: If it becomes necessary to make updates, corrections, or
changes of any type to the SAN configurations originally specified in the
SAN Connect process of the WEB interface, the existing SAN drivers and
support software must be manually uninstalled before running the SAN
Connect process again.

Hub and loop switch restrictions
Fibre channel hubs and loop switches are supported for use with
the StorageWorks NAS Executor E7000. However, there are two
restrictions that an administrator should be aware of.
1. LUNs that were created using the ACS 8.5 firmware are not
visible or manageable in SecurePath 3.1A. This means that
SecurePath cannot be used to administer these LUNs, and
that multiple data paths for a no single point of failure
(NSPOF) configuration will result in multiple instances of
the physical device.

To work around this, the administrator must delete all the
LUNs created with the ACS 8.5 firmware, then re-create
them using the ACS 8.6-1 firmware.
2. Using SecurePath 3.1A, fibre channel arbitrated loop
(FCAL), and ACS 8.6-1 firmware, LUNs cannot be
numbered higher than 63. LUNs D0 through D63 are
available for use, but LUNs D64 through D99 are not.
Support For Enterprise Virtual Array
To use Enterprise Virtual Array storage with the NAS Executor
E7000, you must download a softpaq and solutions paper from
www.compaq.com/products/storageworks/e7000/index.html
The softpaq includes updated support software for the Enterprise
Virtual Array;the solution paper describes how to install the
update, and details best practices for using the Enterprise Virtual
Array with the StorageWorks NAS Executor E7000.
After installing the SoftPaq, return to the SAN Connection
Wizard and finish the initialization.
Cluster Agent Activation
If the StorageWorks NAS Executor E7000 server is part of a
cluster, the Compaq Insight Manager Cluster Agent must be
activated. The Cluster Agent allows administrators to monitor
the state of the cluster and the cluster resources from Compaq
Insight Manager.
To activate the agent click Start->Settings->Control Panel-
>Compaq Management Agents and add the clustering agent to
the active agent list.

SANworks Virtual Replicator
Disk Defragmenter does not work on SWVR
volumes
A portion of the Windows 2000 operating system related to disk
access does not function with SWVR managed disks. This
includes the disk defragmenter program included with Windows
2000.
LVM Defaults to Dynamic Disk
Microsoft Logical Volume Manager (LVM)prompts you to
upgrade to Dynamic disk type. Do not upgrade any Virtual
Replicator created disks to Dynamic type. Press Cancel and
manage your volumes.
Network Disks
The current NAS Executor E7000 implementation of SWVR
does not support network disks. Do not attempt to install this
feature on top of the NAS Executor E7000 image.
Lifeguard and Snapshots
Lifeguard is a service that deletes snapshots automatically when
the amount of pool space in a pool has been exhausted. The
Lifeguard service is a safety mechanism that prevents pool space
depletion. If the pool's snapshot space is depleted because of a
heavy load, blue screens and data corruption could occur. A
snapshot should therefore be viewed as transitory because it can
be deleted at any time without user notification. Refer to the
StorageWorks NAS Executor E7000 by Compaq Administration
Guide for details about the Lifeguard service.
