Releasing a disk drive cam handle
Important:
For hot-swappable FRUs:
Always consult http://now.netapp.com for
current field-replaceable unit (FRU)
replacement procedures.
Adding external storage or using FCP:
You must order and use SFP modules on
your system, if you are connecting external
Fibre Channel storage devices or using FCP
with the system.
Important:
For hot-swappable power supplies:
System shuts down two minutes after you
remove a power supply.

Opening the system
1.
Properly ground yourself.
2.
Loosen the thumbscrew on the controller module
cam handle.
3.
Unplug system cables from the controller module,
as needed.
4.
Pull the controller module cam handle downward and
slide the controller module out of the system. Make
sure that you support the bottom of the controller
module with your free hand.
5.
Remove the controller module cover by completing
the following substeps, using the illustration for reference:
a.
Loosen the thumbscrew on the back of the
controller module.
b.
Gently press the heel of your hand on the indentation
in the controller module cover closest to the cam
handle, then slide the cover toward the back of
the controller module.
c.
Lift the cover straight up off the controller module.
Closing the system
1.
Align the controller module cover with the notches on the
sides of the controller module, then slide the cover down
and forward to seat it.
2.
Align the end of the controller module with the opening in
the chassis.
3.
Gently push the controller module halfway into the
chassis and recable the controller module, then push the
controller module all the way into the chassis.
Result:
For systems in an active/active configuration, the
node reboots as soon as you seat the controller
completely into the chassis.
4.
Firmly push up the cam handle to finish seating the
controller module in the system, and then push the
cam handle to the closed position and tighten the
thumbscrew beneath the cam handle.
5.
Complete the boot process.
IF
your system has a single controller module, plug in
the power supply and turn on the power.
IF
your system is in an active/active configuration,
give back the node by completing the following substeps:
a.
Enter the following command from the partner
console:
cf giveback
b.
On the console of the newly installed controller
module, select Normal Boot (option 1) from the
displayed menu to boot Data ONTAP

Shutting down a controller module
Shut down the target controller module (called a “node” in an
active/active configuration) by completing the applicable
procedure:
If you have an active/active configuration
1.
Check the status of the target node by entering the following
command at the system console of either node:
cf status
2.
Take one of the following actions, depending on the result of
the
cf status
command:
IF
clustering is enabled and neither node is in takeover
mode, go to step 3.
IF
clustering is enabled and the partner node took over the
target node, go to “Opening the System.”
IF
clustering is enabled and the target node took over
the partner node, correct the problem, run the
cf giveback
command from the target node
console, and go to step 1.
3.
Take over the target node by entering the following
command from the partner node’s console:
partner> cf takeover
4.
Go to “Opening the system” when the takeover
is complete.
If you have a single-controller configuration
1.
Enter the following command from the system
console:
halt
2.
Turn off the power supplies and unplug both power
cords from the power source.
3.
Check the nonvolatile memory (NVMEM) LED.
IF
the LED is not flashing, go to “Opening the System.”
IF
the LED is flashing, there is content in the NVMEM that
has not been saved to disk. Reconnect the power supplies to
the power source, reboot the controller module, and repeat
Steps 1 through 3. If repeated attempts to cleanly shut down
the controller module fail, be aware that you might lose any
data that was not saved to disk. Go to “Opening the
System.”
Attention:
Disk drives are fragile. Do not handle them
except when replacing failed disk drives or moving them
to a new chassis.
