Compaq HSG80 Array Controller ACS Version 8.4 Configuration and CLI Reference Guide
7. Put “this controller” into transparent failover mode. Use the following syntax:
SET FAILOVER COPY = THIS_CONTROLLER
The “other controller” inherits “this controller’s” configuration, then restarts.Wait
for it to return to normal operation before continuing.
See details about failover modes in “Selecting a Failover Mode,” page 2–5.
8. If you want to enable mirrored write-back cache in a failover configuration, enter
this command:
SET THIS_CONTROLLER MIRRORED_CACHE
NOTE: Both controllers restart when you set mirror mode. This process can take
up to 5 minutes, depending on the amount of data that must be flushed from the
cache.
For details about caching techniques, see CACHING TECHNIQUES, chapter 2.
9. Set the time on the controller, which provides a baseline for replacing the
external battery, using the following command:
SET THIS_CONTROLLER TIME=DD-MMM-YYYY:HH:MM:SS
NOTE: All values are numbers, except for MMM, which uses the first three
letters of the month. When setting hours, minutes, and seconds—HH, MM,
and SS—you must use 24-hour time.
10. Set up the battery discharge timer:
a. Start Frutil using the following command:
RUN FRUTIL
Frutil displays the following:
Do you intend to replace this controller’s cache battery? Y/N
b. Enter Y(es).
Frutil displays a three-step procedure and prompts you to press return.
c. Press return.
