Compaq HSZ80 manual Destroy/Nodestroy

3–57

■When replacing both controllers, you can replace the first and restart it alone by holding in port button 6 and pressing the reset button on the controller’s operator control panel. This controller picks up any previously saved configuration data on disk and uses it to set up the subsystem configuration. Replace the second controller using the SET FAILOVER COPY command to copy the configuration information from the operating controller.

■Both controllers update the saved data; each writes to only those devices currently preferred to it. This process prevents conflicting data transfer.

Destroy/Nodestroy

Specify whether to destroy or retain (nodestroy) the user data and metadata when you initialize a disk drive that has been previously used in a mirrorset or as a single-disk unit:

NOTE: The DESTROY and NODESTROY switches are only valid for striped mirrorsets and mirrorsets.

■DESTROY (default) overwrites the user data and forced-error metadata on a disk drive when it is initialized.

■NODESTROY preserves the user data and forced-error metadata when a disk drive is initialized. Use NODESTROY to create a single-disk unit from any disk drive that has been used as a member of a mirrorset. See the REDUCE command in Chapter 5, “CLI Commands,” for information on removing disk drives from a mirrorset.

The NODESTROY switch is not valid for RAIDsets and single-disk configura- tions.
