Confirming the fi rmware version
After replacing a controller, verify that the latest firmware for your
controller is installed. Go to the HP support website for your device,
and if newer firmware is available, download the firmware from the
Web and install it on the controller(s).
IMPORTANT:
Because this device is part of the ExDS9100 solution, see the
ExDS9100 administration guide for additional instructions. The
ExDS management software may automatically update the
firmware to a required version.
IMPORTANT:
In dual-controller configurations, both controllers must execute
thesameversionoffirmware. If the controllers have different
firmware versions, the storage system responds as follows:
• Cold boot method
If a second controller is installed while the device is powered
off, the system compares the firmware versions of both
controllers at power on and clones the most recent version
from one controller to the other controller.
• Hot plug method
If a second controller is installed while the device is powered
on, the system clones the firmware version of the active
controller to the second controller.
CAUTIO
N:
In hot-plug cloning, it is possible for firmware on a
newly installed controller to be downgraded to an earlier
version. If this occurs, schedule a maintenance window
and update the firmware of both controllers to the latest
version.
Verifying component status
• Verify that the SAS controller LED on the rear of the chassis is green.
• Verify that no error messages are displayed on the seven-segment
display.
Ret
urning the failed component
