Verifying component failure

Use the following methods to verify component failure:
• Analyze any failure messages received. Fault monitoring software
from HP (WEBES) provides a recommended solution.
• Check status using HP Command View EVA:
1. In the navigation pane, select Storage system > Hardware >
Controller Enclosure > Controller.
2. The status is displayed in the Condition/State field. An opera-
tional state of (Failed) would indicate a fault that may require
a replacement.
3. The state of the embedded switch can be observed on the Host
Ports tab for the controller. The states are: not installed, good,
attention required, failed, and unknown.
4. 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.
• For failures or degraded performance with the embedded switch,
see the troubleshooting section of the HP StorageWorks Fabric OS
X.y administrator guide, where X.y is the version of the switch oper-
ating system. To obtain this guide, go to
port/manuals, click Disk Storage Systems in the storage section, and
click on your EVA disk array.
• Check the controller status LEDs as shown in

Removing a controller
CAUTION:
Verify the location of the controller being serviced. Removing
the wrong controller can result in data loss.
NOTE:
• Replacement controllers do not have DIMM modules, therefore
the DIMMs from the controller being removed must be trans-
ferred to the replacement controller.
• HP recommends that you replace the controller while the con-
troller enclosure is powered on to ensure the firmware on the
redundant controller is copied to the controller being installed.
1. Halt I/O to the controller with HP Command View EVA:
a. In the navigation pane, select Storage System > Hardware >
Controller Enclosure.
b. Select the appropriate controller (Controller 1 or Controller 2)
to halt.
c. Click the Shut down tab.
d.
In the Halt Controller section of the Shut Down Controller
window, click Halt. This halts controller processing while the
power remains on.
2.
Disconnect the Fibre Channel, Ethernet, and console cables from
the halted controller. Ensure they are marked to facilitate
reconnecting later.

Indication
Flashing amber indicates a controller crash,
or the system is inoperative and attention
is required. Solid amber indicates that the
controller cannot reboot or the switch is in-
operative, and that the controller should be
replaced. If both the solid amber and solid
blue LEDs are lit, the controller has com-
pleted a warm removal procedure, and can
be safely swapped.
Not used.
Green LED that indicates write-back cache
status. Slow flashing green LED indicates
standby power. Solid green LED indicates
cache is good with normal AC power ap-
plied.
Amber LED that indicates DIMM status. The
LED is off when DIMM status is good. Slow
flashing amber indicates cache/DIMMs are
being powered by battery (during AC
power loss). Solid amber indicates a DIMM
failure.
