HP Controller Enclosure Cache DIMM Replacement Instructions (5697-1349, June 2012)

When replacing a DIMM, it is important that you
upgrade the firmware before you install the DIMM.
Failure to do so results in failure of the array to boot.
• Alloy (gray)-colored latches on components like
the controller indicates that the component is
warm-swappable. Halt the I/O of a controller
being serviced with HP P6000 Command View
before removing this component.
• There are two controllers at the rear of the
controller enclosure. See Figure 1 (page 2) for
the locations.
• Your controller enclosure model may vary slightly
from what is illustrated in this document.

Verifying component failure
Use the following methods to verify component failure:
• Analyze any failure messages received. HP Insight
Remote Support Software provides a
recommended fault monitoring solution.
• Check status using HP P6000 Command View:
1. In the navigation pane, select Storage
system→Hardware→Controller enclosure
and then select a controller.
2. The status is displayed in the Memory section
and the Condition/State section.
When a DIMM fails, the status in the Memory
section could show a memory amount
inconsistent with the amount known to be
installed.
The Cache state in the Condition/State
section could show an operational state of
(Failed) to indicate an improperly seated
DIMM or a fault that requires a DIMM
replacement.
3. To help identify the correct controller, click
Locate→Locate On. This causes the blue UID
indicator to light on the controller module at
the rear of the controller enclosure.
4. View the controller event log to determine
which DIMM has failed.
• Observe the controller status LEDs as shown in
Figure 2 (page 2) and Table 1 (page 2).

IndicationLEDItem
Blue LED used to identify a specific
controller module within the enclosure
1
or the iSCSI or iSCSI/FCoE module
(P63x0/P65x0 EVA only) within the
controller.
Green LED indicates controller health.
LED flashes green during boot and
becomes solid green after boot.
2
Flashing amber indicates a controller
termination or the system is inoperative
3
and attention is required. Solid amber
indicates that the controller cannot
reboot and should be replaced. If both
the solid amber and solid blue LEDs
are lit, the controller has completed a
warm removal procedure, and can be
safely swapped.
Applicable to the P63x0/P65x0 EVA
only. Amber LED indicates the iSCSI
MEZZ4
or iSCSI/FCoE module status that is
communicated to the array controller.
Slow flashing amber LED indicates an
IP address conflict on the management
port.
Solid amber indicates an iSCSI or
iSCSI/FCoE module critical error or
shutdown.
Green LED indicates write-back cache
status. Slow flashing green LED
5
indicates standby power. Solid green
LED indicates cache is good with
normal AC power applied.
Amber LED indicates DIMM status. The
LED is off when DIMM status is good.
6
Slow flashing amber indicates DIMMs
are being powered by battery (during
AC power loss). Solid amber indicates
a DIMM failure.
