Compaq HSZ80 manual 121, SET Nofailover, SET Failover SET Multibusfailover SET Nomultibusfailover

5–121

Specify NODESTROY_UNFLUSHABLE_DATA to leave the unwritten data intact in the failed controller’s write-back cache. When the failed controller is replaced and placed into service, the write-back cache data is flushed to the appropriate devices.

Specify DESTROY_UNFLUSHABLE_DATA to reconfigure the operational controller before replacing the failed controller. The unwritten data of the failed controller may reference devices not present in the new configuration. If you do not destroy the old configuration data, it may conflict with the new configuration and cause the subsystem to behave unpredictably.

CAUTION: Unflushed data cannot be recovered after it is destroyed.

Example
