CAUTION
ꢀ Do not install the additional disk enclosure and disk array unit on an unstable place.
If so, some substances may be dropped to cause you to be injured.
ꢀ Do not install the additional disk enclosure and the power cords in an area with
direct sunshine or near an apparatus generating heat such as a heater. If so, a fault
may occur. Further, the coating of the power cord may be melted to cause fire or
electric shock to occur.
ꢀ Insert the plug of a power cord to an AC outlet securely. Any power cord shall be
routed with sufficient margin to avoid excess force from being given to the plugs of
the power cord or the power cord itself. If a power cord is removed from the AC
outlet during operation, data may be lost and/or a fault may occur.
ꢀ To prevent electric shocks, connect a power cord to an AC outlet with earth
terminal. Connection of the earth line to a gas tube is extremely dangerous. Never
do it.
ꢀ Connect or remove a peripheral from the additional disk enclosure after turning off
all the powers of the additional disk enclosure and peripherals and pulling out the
power cords from the AC outlets. If not, some units may be broken and/or you may
be electrically shocked.

To install the unit in a rack, observe the following guidelines.
1. TMRA – If installed in a rack, consideration should be given to installing the
equipment in an environment compatible with the TMRA.
2. Reduced Air Flow – Installation in a rack should be such that the amount of air flow
required for safe operation of the equipment is not compromised.
3. Mechanical loading – Mounting of the equipment in the rack should be such that a
hazardous condition is not achieved due to uneven mechanical loading.
4. Circuit Overloading – Consideration should be given to the connection of the
equipment to the supply circuit and the effect that overloading the circuits might
have on overcurrent protection and supply wiring. Appropriate consideration of
equipment nameplate ratings should be used when addressing this concern.
5. Reliable Earthing – Reliable earthing of rack-mounted equipment should be
maintained. Particular attention should be given to supply connections other than
direct connections to the branch circuit (e.g., use of power strips).

2. FEATURES OF ADDITIONAL DISK ENCLOSURE
The additional disk enclosure has the following features.
NF2300-SE41E is a high-performance additional disk enclosure developed for the
NF2300-SR4xxE disk array unit connected to the NEC Express5800 basic processing
unit, NX7000 basic processing unit, or CX5000 basic processing unit.
The additional disk enclosure NF2300-SE41E is not equipped with disk drives at the
shipment. To use the additional disk enclosure, add disk drives sold separately.
Up to 15 disk drives can be installed in NF2300-SE41E.
The disk drives for disk array unit NF2300-SR4xxE can be added by connecting the
additional disk enclosure NF2300-SE41E (up to 13 disk enclosures, 210 disk drives).
The combination of the additional disk enclosure and disk array unit NF2300-SR4xxE
enables a defected disk drive to be replaced with a new one without system shutdown.
Further, the additional disk enclosure has the auto rebuild feature which automatically
starts data recovery after the replacement of the defected disk drive.
If a single disk drive is specified as the spare disk, the data in the defected disk drive can
be immediately recovered in the spare disk. The use of this hot spare feature as well as the
auto rebuild feature allows the data in the defected drive to be automatically recovered in
the spare disk as soon as a disk drive is defected. This improves the system reliability.
Refer to "NF2300-SR4xxE Disk Array Unit User's Guide" for details of hot spare feature.
Further, owing to the redundant configuration of the adapter and power supply, the entire
system is not shut down if any part of the system is defected during operation.
See Section 9.2 "Optional Components" for the product names and part numbers of
options.

When you change a failing disk to a spare disk, confirm the following to get
the spare disk to function normally:
ꢀ The capacity of the spare disk is equal to or greater than that of the failing
disk.
ꢀ The rotational speed of the spare disk is equal to or faster than that of the
failing disk.
Therefore, if a large-capacity disk is defined as a spare disk, it can cover all
the disks of a high-speed drive. However, if your disk array unit contains disks
of different capacities or different rotational speeds, you should define a spare
disk matching the capacity and rotational speed of each disk in order to clarify
disk management.
Up to 2 spare disks can be installed for each disk enclosure. Up to 16 spare
disks can be installed for the entire disk array unit.
<Installation procedure>
Disk drives may be installed in the additional disk enclosure with the powers of the
additional disk enclosure, disk array unit, and host unit being ON.
For the replacement of one or more dummy trays and disk drives, replace them one by
one. Do not remove two or more dummy trays at a time.
(1) Putting of location label
Before installing the disk drive, select the location label appropriate to the location
where the disk enclosure is to be installed, and put it on the additional disk drive.

7. HANDLING OF ADDITIONAL DISK ENCLOSURE
This chapter describes how to handle the additional disk enclosure.
7.1 Notes on Handling of Additional Disk Enclosure
Note the following in use of the additional disk enclosure. Invalid handling of the
additional disk enclosure may cause it to be defected and/or some data to be broken.
ꢀ If the HDD READY LED (green) blinks, the disk access operation is
indicated on the host system, or the initialization is being operated, do not
turn on/off the powers of the additional disk enclosure. Do not reset the
host system.
ꢀ If the HDD READY LED (green) is lit or blinks and the disk access
operation is indicated on the host system, do not give vibrations and
shocks to the additional disk enclosure.
ꢀ Because the additional disk enclosure is a precision device, it shall not be
subject to hard vibration or shock.
The features of the additional disk enclosure are effective only for the
hardware failure (e.g., the hard disk is physically damaged or inoperative).
The software failure (e.g., the data is lost or rewritten due to program
excursion) is not covered by these features. When the software failure would
occur, the system could seriously be damaged. To minimize the damage, be
sure to back up the data periodically.

7.2 Power On/Off of Additional Disk Enclosure
This section describes how to turn on or off the power of the additional disk enclosure.
Turning on or off the power carelessly may cause some data to be broken, some software
to operate incorrectly, and/or the device to be defected.
(1) AC power-on
a) Before turning on the AC power, check for loose disk drives by pushing each
disk drive.
b) Turn on all the disk enclosures connected with the array controller, and then
turn on the array controller. Alternatively, turn on the array controller and all
the disk enclosures connected with the array controller at the same time.
The additional disk enclosure has the redundant power configuration to prevent
the entire unit from shutting down due to a single failure. Therefore, when
turning on the disk enclosure, turn on all the power switches (of the array
controller and disk enclosures) at the rear of the unit.
When turning on the power switches, confirm that the POWER GOOD LED
(green) of the power supply and the POWER LED (green) on the front panel of
the unit go on. Power supply starts, and the POWER LED (green) is on while
the power switches are on.
The additional disk enclosure performs the self-test and initialization
immediately after the power is turned on. When the self-test and initialization
terminate and the disk enclosure becomes ready, the READY LED of the
adapter stops flashing and enters the on state. The READY LED of the
controller installed on the disk array unit also stops flashing and enters the on
state.
The additional disk enclosure (including the connected disk array unit) takes
four minutes (at maximum) to start.

[Power-on procedure]
Turn on the power switches in the following order (1) to (3):
(3) Host system
(1) Power switches of disk enclosures
(2) Power switches of array controller
(May be turned on at the same time the power switches of disk enclosures are turned on.)

(2) Notes on turning off AC power
The disk array unit to be connected with the additional disk enclosure periodically
writes data from the cache memory onto a disk. If you turn off the AC power
before completion of write to the disk, the remaining data on the disk is backed up
by the battery backup units.
However, the backup time is limited (4 days if the cache memory has the allowable
maximum capacity and the two battery backup units are fully charged). To
securely protect data, turn off the AC power after all the data has been written from
the cache memory in the disk array unit onto the disk. Turn off the AC power
according to the procedure explained in "(3) Turning off AC power".
1. Turn off the host system and the host bus adapter or the FC-AL switch.
Alternatively, offline all the buses connected to the host system that is
connected with the disk array unit.
2. If NEC Storage DynamicDataReplication is used, execute the Unpair
command.
3. Turn on the shut down switch (toggle switch with SHUT DOWN indicated) of
the LAN card in the array controller. (*1)
4. Confirm that [SDN LED] of the LAN card in the array controller is on, and
then turn off the AC power according to the procedure explained in "(3)
Turning off AC power".
[SDN LED] flashes while data remaining in cache memory is being written
onto the disk drive. Do not turn off the AC power while it is flashing. (*2)
Relationship between [SDN LED] states and operations of the disk array unit:
Normal state:
Off
During cache data write onto disk:
Flashing
Completion of cache data write onto disk: On
Writing cache data onto a disk drive usually takes about 10 minutes and 20
minutes at maximum.
If cache data is not written onto a disk drive normally, the LEDs of the LAN
card enters the following states. In this case, contact your maintenance
service agent.
RDY LED: On
FLT LED: Flashing
SDN LED: Off
5. Turn off the shut down switch (toggle switch with SHUT DOWN indicated) of
the LAN card in the array controller. (*3)

*1 – The shut down switch has a locking mechanism. To turn on/off the switch, hold
and raise the lever.
– While the shut down switch is on, the disk array unit does not accept any I/O
operation by the host system.
(The Link UP LEDs of the controller's HL0 and HL1 go off.)
*2 – If you turn off the AC power of the disk array unit during write operation (with
SDN LED flashing) by mistake, the backup mode is enabled. (In this case, the
controller's [BAT LED] goes on.)
– If you turn off the AC power of the disk array unit during write operation (with
SDN LED flashing) by mistake, turn on the AC power of the entire disk array
unit (including the power of the additional disk enclosure) again. When the disk
array unit has started (when the READY LED of the controller on the array
controller stops flashing and enters the on state), turn off the shut down switch
and then turn it on to complete the write operation.
– Even if you turn off the AC power after [SDN LED] goes on, [BAT LED] goes
on in the following case:
NEC Storage DynamicDataReplication is used, but you attempt to write the
remaining cache data before executing the Unpair command.
In the above case, turn on the AC power of the entire disk array unit again.
When the disk array unit has started (when the READY LED of the controller on
the array controller board stops flashing and enters the on state), turn off the shut
down switch. Then, execute the Unpair command for paired disks under NEC
Storage DynamicDataReplication, and turn on the shut down switch to complete
the write operation.
*3 – Even if you forget to turn off the shut down switch, the disk array unit starts
normally when being turned on next time, and accepts I/O operation by the host
system. (Normal operation)
– Turning off the shut down switch does not influence general operation of the disk
array unit.
– When turning off the disk array unit again, turn off the shut down switch and then
turn it on. The system starts writing data remaining in cache memory onto the
disk drive.

(3) Turning off AC power
Turn off the powers of the additional disk enclosure and disk array unit in the
following procedure.
a) Turn off the host system or FC-AL switch, and then perform the procedure
explained in "(2) Notes on AC power-off".
b) After finishing the operation in a, turn off the array controller and then all the
disk enclosures including additional disk enclosures. Alternatively, turn off
the array controller and all the disk enclosures including additional disk
enclosures connected with the array controller at the same time.
The additional disk enclosure has the redundant power configuration to prevent
the entire unit from shutting down due to a single failure. Therefore, when
turning off the disk array unit, turn off the two power switches at the rear of the
disk enclosure.
Be careful that data may be lost if you turn off the disk enclosures before the
array controller.

7.3 LD (Logical Disk) Setting Procedure
To use the additional disk enclosure, first install the disk drive and then set the RAID level
of the installed disk drive, and assign the logical disk (LD) configuration. When the disk
drives are added, the RAID level and logical disk (LD) must be set appropriately.
Set the RAID level by using the "NEC Storage Manager", or contact the service engineer
with expert knowledge in your service representative for setting of the RAID level.
If the disk array unit is connected with NF9520-SH01E, changing the LD
(logical disk) configuration may cause the OS to fail to recognize the logical
disks.
Be sure to restart the host system after changing the LD configuration.
7.4 Spare Disk Setting Procedure
Spare disk can be set only in RAID level 1, 5, or 10.
Set the spare disk by using the "NEC Storage Manager", or contact the service engineer
with expert knowledge in your service representative for setting of the spare disk.
For spare disk, make sure to assign the disk drive in slot 14.
If slot 14 already contains a disk drive for a spare disk, install the additional
disk drive in slot 13.
When you change a failing disk to a spare disk, confirm the following to get
the spare disk to function normally:
ꢀ The capacity of the spare disk is equal to or greater than that of the failing
disk.
ꢀ The rotational speed of the spare disk is equal to or faster than that of the
failing disk.
Therefore, if a large-capacity disk is defined as a spare disk, it can cover all
the disks of a high-speed drive. However, if your disk array unit contains disks
of different capacities or different rotational speeds, you should define a spare
disk matching the capacity and rotational speed of each disk in order to clarify
disk management.
Up to 2 spare disks can be installed for each disk enclosure. Up to 16 spare
disks can be installed for the entire disk array unit.
