Verify Controller Component Status; Replace A Controller Dimm - Oracle FS1-2 Customer Service Manual

Verify Controller Component Status

1 From Guided Maintenance, verify that the status is Normal.
You can also verify the status by navigating to System > Hardware and
then selecting a chassis. The Overview page for the selected chassis lists the
status of each component.
Note: The Controller status will be visible several minutes after being
powered on. The Oracle FS1 Flash Storage System must load the operating
system software on the Controller, then validate the status of the Controller
and the hardware before it will allow the Controller to rejoin the system
and return to Normal status.
2 Review the status of the LEDs to confirm a status of Normal.

Replace a Controller DIMM

Dual in-line memory modules (DIMMs) provide random access memory (RAM)
for the central processing units (CPUs) configured in the Controller. DIMMs are
connected to the DIMM slots located on both sides of the central processing unit
(CPUs) and heat sinks on the Controller motherboard. A failed DIMM might
cause the Controller to be brought offline and must be replaced as soon as
possible.
Prerequisites:
•

•
•
A basic Oracle FS1 Flash Storage System has two standard DIMMs and a
performance Oracle FS1 Flash Storage System has 12 standard DIMMs. Each
DIMM in the Oracle FS1 Flash Storage System have 16 GB memory.
DIMMs are customer replaceable units (CRUs). Replacing a DIMM requires you
to bring the Controller offline. The following figure depicts a DIMM memory
module.
Ensure that you have a Phillips Number 2 screwdriver with at least a 4-inch
shaft.
Before handling a component, touch a grounded surface to discharge any
static electricity.
Attach an electrostatic discharge (ESD) wrist strap to your wrist, and stand
on an ESD mat while replacing components.
Fail over the Controller before replacing the component using Guided
Maintenance.
Note: The Controller must be failed over to prevent data loss or data
corruption during the component replacement process.
Ensure that all DIMM slots are filled with either filler panels or DIMMs to
ensure proper airflow.
