1.1 World Wide Web Site

For the latest information on DIGITAL OpenVMS Disk Services for Windows NT, including late-breaking release notes, product updates, and documentation, visit our World Wide Web site at:

1.2 If You Installed the Field Test Kit

If you installed the field test kit for DIGITAL OpenVMS Disk Services for Windows NT:

Uninstall the field test kit on your Windows NT computers before you install the client component of Version 1.0 of DIGITAL OpenVMS Disk Services for Windows NT.
This removes the field test Program group that you no longer need. It also ensures that you cannot accidentally delete files needed by Version 1.0 by uninstalling the field test kit when Version 1.0 is installed.
When you have installed the client component of Version 1.0 of DIGITAL OpenVMS Disk Services for Windows NT, use NTDS Administrator to reconfigure the Windows NT computers.
Your existing configuration information is lost in Step 1 above.

1.3 Shutting Down the Windows NT Computer

When you shut down a Windows NT computer, it automatically flushes to disk all the unwritten data in its local cache; this includes data for its virtual disks as well as for its physically attached local disks. The computer does not shut down until all of the data is safely on disk.

When you shut down the computer, if it has lost a connection to a disk service and is currently trying to reconnect to the service, the writes are stalled and the shutdown pauses until the computer manages to reconnect to the service and write the data to disk.

If you turn the computer off before it manages to reconnect to the disk service and write the data to disk, you lose data associated with the disk service's virtual disk. You may also lose data associated with the computer's physically attached local disks if writes to those disks have not yet been flushed from the Windows NT cache.

Before you shut down a Windows NT computer:

Check that the computer has not lost the connection to any disk services (follow the instructions in the Troubleshooting chapter of the Guide to DIGITAL OpenVMS Disk Services for Windows NT), or
Disconnect the computer from all of its disk services, using NTDS Administrator.

1.4 Connecting a Restored Disk Service to the Same Computer

If you back up a disk service from OpenVMS, the virtual disks associated with the restored and the original disk services have the same disk signature.

This means that if you connect the same Windows NT computer to both the original and the restored disk service, and you then run the Windows NT Disk Administrator you will get a popup window asking if you would like to change the disk signature of the restored disk service. Click Yes to let Disk Administrator make this change.
