9. Repeat step 8 (on page 209) on both controllers (“this controller” and the
“other controller”) until no unwritten data remains in either cache module
memory.
10. Shut down both controllers by entering the following commands:
HSGA> SHUTDOWN OTHER_CONTROLLER
HSGA> SHUTDOWN THIS_CONTROLLER
Note: After the controllers shut down, the Reset buttons and the first three LEDs turn
on. This can take several minutes, depending on the amount of data that needs to be
flushed from the cache modules. Proceed only after the Reset buttons stop flashing and
remain solid.

substeps:
a. Remove the program card ESD cover from controller A.
b. Press and hold the Reset button while ejecting the old program card.
c. After the program card is ejected, release the Reset button.
d. Repeat substep a through substep c for controller B.
Note: In substep e and substep f, the simultaneous release of the Reset buttons is
critical to ensure that both controllers are restarted and upgraded simultaneously.
e. Simultaneously press and hold the Reset button on both controllers, and
insert a new program card into each controller.
f. Simultaneously release the Reset buttons.
Both controllers restart.
Note: A controller restart can take as long as 60 seconds, indicated by the temporary
cycling of the port LEDs and a flashing Reset button. Disregard messages pertaining to
misconfigured controllers or failover status.
g. Install a program card ESD cover on each controller.
