Restoring Disk Configuration Information (114872)

SUMMARY

Typically, only the Windows NT installation that created a volume set, stripe set without parity, mirror set or stripe set with parity recognizes and is able to use that set. However, another installation of Windows NT or Windows NT Advanced Server can be enabled to recognize and use the set by using Disk Administrator to save the disk configuration information in the Windows NT installation that created the volume and then restoring the information under the other Windows NT installation.

MORE INFORMATION

See pages 528 and 529 of the Windows NT Advanced Server "System Guide" for the specific steps to saving and restoring disk configuration information.

Once the disk configuration information from another installation of Windows NT is restored, the current installation will recognize and be able to use the volume sets, stripe sets with and without parity, and mirror sets created by another installation of Windows NT. After disk configuration information is restored:

Installations of Windows NT Advanced Server can perform any function on a volume created by another installation of Windows NT that they could perform on volumes they created. This includes breaking mirrors and regenerating stripe sets with parity.

-AND-
Installations of Windows NT can perform any function on a volume set or stripe without parity created by another installation of Windows NT that they could perform on volumes sets or stripes without parity that they created. They can also recognize, read from and write to mirror sets and stripe sets with parity created by Windows NT Advanced Server. However, Windows NT cannot break a mirror set or regenerate a stripe set with parity. In the event a partition is lost in a mirror set or stripe set with parity, recovery of the lost partition must be performed by Windows NT Advanced Server.
