• Port-colored (purple) handles on components like the battery module means the component is hot-swappable and can be replaced without having to power the system down. • There are two battery modules under the bezel on the front of the controller enclosure. See Figure 1 (page 2) for the locations. Each battery provides power to the controller directly across from it in the enclosure. Battery 1 (B1) provides power to controller 2 (C2) and battery 2 (B2) provides power to controller 1 (C1). • Your controller enclosure model may vary slightly from what is illustrated in this document. Figure 1 Battery module locations Controller Enclosure Properties window. This causes the blue Unit ID indicator to blink on the controller enclosure (not the individual controller in the enclosure). • Observe the battery module status LEDs. ◦ Solid green-Power turned on and functioning properly ◦ Blinking green-Maintenance activity in progress, such as testing or charging ◦ Solid amber-Fault condition that cannot support cache activity. LUNs have failed over to the other controller. ◦ Blinking amber-Degraded condition, and should be replaced soon. Depending on the charge state of the battery, LUNs may or may not have failed over to the other controller. ◦ Off-Module not fully connected or powered down Removing a battery module 1. Remove the enclosure front bezel by grasping both ends and pulling it off the enclosure. Figure 2 Enclosure bezel removal 1. Battery 1 2. Battery 2 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. • Verify the battery status using HP P6000 Command View: 1. In the navigation pane, select Storage system→Hardware→Controller enclosure. 2. In the contents pane, select the Power tab. The status is displayed in the Cache Battery fields. An operational state of (Failed) indicates a fault that can require a battery replacement. 3. To help identify the correct enclosure in the rack, select Locate→Locate On in the 2. Verify the correct battery module to replace. Battery 1 powers controller 2 and battery 2 powers controller 1. NOTE: If the battery amber LED is lit solid, the LUNs owned by the controller with the faulted battery have already failed over to the other controller. If the battery amber LED is blinking, the LUNs may or may not have failed over to the other controller, and if not, will fail over when the degraded battery is removed. 3. Grasp the handle on the battery module and pull it out a short distance. Page 2

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.
•
Verify the battery status using HP P6000
Command View:
1.
In the navigation pane, select
Storage
system
→
Hardware
→
Controller enclosure
.
2.
In the contents pane, select the
Power
tab.
The status is displayed in the Cache Battery
fields. An operational state of
(Failed)
indicates a fault that can require a battery
replacement.
3.
To help identify the correct enclosure in the
rack, select
Locate
→
Locate On
in the
Controller Enclosure Properties window. This
causes the blue Unit ID indicator to blink on
the controller enclosure (not the individual
controller in the enclosure).
•
Observe the battery module status LEDs.
Solid green—Power turned on and functioning
properly
◦
◦
Blinking green—Maintenance activity in
progress, such as testing or charging
◦
Solid amber—Fault condition that cannot
support cache activity. LUNs have failed over
to the other controller.
◦
Blinking amber—Degraded condition, and
should be replaced soon. Depending on the
charge state of the battery, LUNs may or may
not have failed over to the other controller.

Off—Module not fully connected or powered
down
Removing a battery module
1.
Remove the enclosure front bezel by grasping
both ends and pulling it off the enclosure.
Figure 2 Enclosure bezel removal
2.
Verify the correct battery module to replace.
Battery 1 powers controller 2 and battery 2
powers controller 1.
NOTE:
If the battery amber LED is lit solid,
the LUNs owned by the controller with the
faulted battery have already failed over to
the other controller. If the battery amber
LED is blinking, the LUNs may or may not
have failed over to the other controller, and
if not, will fail over when the degraded
battery is removed.
3.
Grasp the handle on the battery module and pull
it out a short distance.
