Problem Possible cause Solution
Real-Time Clock (RTC)
loses its time.
The rechargeable battery for
NVMEM also powers the
real-time clock. If this battery
is disconnected for more than
a few seconds or the battery
is discharged, the real-time
clock might be reset.
Plug the battery back in to the motherboard and reset
the clock to the correct time.
The N3700 storage system
does not recognize any of
the installed disk drives.
The 1 Gb/2 Gb switch is not
set to the 1 Gb position.
1. Power off the N3700 storage system.
2. Move the switch to the 1 Gb position. See Step 6
of “Connecting your N3700 storage system to a
network” on page 7.
3. Power on the N3700 storage system.
My IBM service
representative replaced a
CPU module and now the
new module can’t see the
disks
The disk ownership
mechanism ties disks to CPU
module system IDs. If your
IBM service representative
replaced a CPU module with
a new one in, the disks are
still stamped with the system
ID of the old module.
Perform a disk reassign command. Use the help
command to get the exact syntax.
I have unowned disks; why
didn’t Data ONTAP use them
to reconstruct a failed drive?
The disks need to be
“SPARES,” not “unowned.”
Assign the disks as spares.
The battery is discharged
and Data ONTAP won’t boot.
The battery voltage is too low
to hold data for 3 days during
a power-out condition.
If you turn on the machine
and let it sit at the firmware
(CFE) prompt, it does not turn
on the charger. You need to
boot Data ONTAP to get the
software to turn on the battery
charger.
You have two main options at this point:
1. Leave the N3700 storage system alone for a few
hours to let the battery charge.
2. Press Ctrl-C to override this check.
Executing a priv set advanced command and an nv
command shows you the current status of the battery
(if you pressed Ctrl-C to override the stall condition).
You can also try out the environ chassis Battery
command (note that “Battery” is case-sensitive).
In either case, the battery charger is turned on and
recharges the battery over the next few hours.
CFE failed, creating a POST
code.
CFE firmware runs a series of
Power-On-Self-Tests (POST)
before trying to load Data
ONTAP. If any of the POSTs
fail, a code is printed.
See “POST error messages” on page 44 for a
description of the error.
