• 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 Operational State field. An
(Failed) would indicate a fault that may
operational state of
require a replacement.
3. To help identify the correct controller, click Locate > Locate On.
This causes the blue UID indicator to light at the front and rear
of the controller enclosure.
• Check the controller enclosure status LEDs as shown in Figure 1
and Table 1.

4. Remove the operator control panel (OCP).
a. Squeeze the OCP latch tabs (1, Figure 3) and swing the panel
out until fully open (2).
CAUTION:
Handle the OCP by its metal frame only. This ensures
that the electronic components are not damaged by static
discharge.
b. Grasp the OCP by its metal frame and pull it out of the
