Figure 90 shows only a portion of the resulting display—an arrow points to
the pertinent status indication.
Figure 90: Screen display indicating whether flushed data remains in cache
Note: Repeat step 6 (on page 183) 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.
11. Upgrade the software on both controllers by performing the following
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 (starting on page 207), the simultaneous release of
the Reset buttons is critical to ensure that both controllers are restarted and upgraded
simultaneously.
Cache:
256 megabyte write cache, version 0022
