Compaq HSZ80 Array Controller ACS Version 8.3 Configuration and CLI Reference Guide
■ 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.
