HP EVA Updating Product Software Guide (xcs10001000) (5697-2423, December 2012)

Figure 22 Initiating firmware code load page
CAUTION: If you are performing an upgrade on an EVA6400/8400 during heavy I/O
load, processing of the System Data Collector file component could time out and one of the
following error messages may appear:
If either error message appears, click OK. Another message appears, indicating that the array
is unresponsive; wait for communication to be re-established between HP P6000 Command
View and the array. When the array is available, the array appears as available in the
navigation pane. Continue with Step 16 to verify that the upgrade completed successfully.
After Figure 22 (page 50) appears, the controllers resynchronize and begin running the new
controller software. Once resynchronization is complete, the controllers are ready for host
commands. I/O processing does not begin until the hosts complete recovery from the disruption
of resynchronization. Other code in the array, such as I/O module firmware, is updated,
which can take up to 10 minutes to complete. During this interval, the Storage System Updating
Firmware page opens (Figure 23 (page 50)).
