Note: After the controllers shut down, the Reset buttons and the first three LEDs on both
controllers turn on (see Figure 38 on page 226). This could take several minutes, depending on
the amount of data that needs to be flushed from the cache modules. Proceed only after both
Reset buttons stop flashing and remain on.
I 9. Upgrade the software on both controllers:
Note: After step 9 is performed, the previous ACS version cannot be restored to this subsystem
without performing the downgrade process, which should be performed only by HP authorized
service personnel.

b. While pressing and holding the controller Reset button, eject the old program card.
c. After ejecting the program card, release the Reset button.
d. Repeat step a through step c for Controller B.
Note: In step e and step f, the simultaneous release of the Reset buttons is essential 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.

misconfigured controllers or failover status.
g. Install a program card ESD cover on each controller.
Caution: Stop upgrading the initiator site controllers at this point and proceed to upgrade
the target site controllers. Failure to upgrade the target site controllers at this point could
cause the initiator and target site controllers to crash and prevent the host from accessing
data stored in these subsystems.
The initiator site shutdown upgrade procedure continues on page 236 after the target site
shutdown upgrade procedure.
Continue the shutdown upgrade procedure by executing the following steps on the target site
controllers.
