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.

power cord to an outlet of 100 - 120 VAC power at 50 or 60 Hz.
The additional disk enclosure has the redundant power configuration to prevent the
entire unit from being shut down by a single failure. In the configuration, connect
two power cords in use of the additional disk enclosure.

While the additional disk enclosure can accept the power of 100 - 240
VAC (50/60 Hz), the power cord coming with the additional disk
enclosure can only accept 100 - 120 VAC. Use 100 VAC (50/60 Hz)
when the attached power cord is used. Using power of different voltage
may cause electric shock, smoke, and/or fire to occur.

(2) Power switch

The power switch is used to turn on/off the power of the additional disk enclosure.
The disk enclosure has the redundant power configuration to prevent the entire disk
array unit from shutting down due to a single failure. Therefore, turn on/off the two
power switches when operating the disk enclosure.

(3) Cooling fans

When the power switch is set to ON, two cooling fans are rotating. Note that the
ventilating holes are not blocked.

- 11 -

 Install the disk enclosure so that the ventilating holes may not be

blocked. If either or both of the ventilating holes are blocked, the
internal temperature of the disk enclosure may increase to cause a
fault to occur.

 The disk enclosure is equipped with 4 fans in total. Even if a fan

fails, the air-cooling conditions for the entire disk enclosure are
satisfied. However, to guarantee the safety operation of the disk
array unit, replace the power supply for disk enclosure as soon as
possible. Replacing the defected fan means that two fans are
stopped, therefore, perform the replacing work within three minutes.

(4) POWER GOOD LED (green)

The POWER GOOD LED is lit green when the AC power is supplied to the
additional disk enclosure and the power switch is set to ON. The LED is off if the
power switch is set to OFF or a fault occurs in the power supply.

(5) POWER FAULT LED (orange)

The POWER FAULT LED goes on if a fault occurs in the power supply (including
fan fault). The LED is off while the power supply operates normally.

(6) Power cord stopper

The power cord stopper prevents the power cord from being removed unexpectedly.

(7) Ejector

The ejector is used to install or remove the power supply from the additional disk
enclosure. Loosen the screw before using the ejector.

When inserting or replacing the power supply for the disk enclosure into
the disk enclosure, push it as far as it will go and then secure it with the
screws.
Incorrect insertion may cause a power supply failure again.

When replacing a power supply for the disk enclosure, prepare the new
power supply before removing the old one, and then replace it within
about 3 minutes.
The following are heating units of the disk enclosure:
A) Disk drives
B) Power supplies for the disk enclosure
The fans in the power supplies for the disk enclosure serve as cooling
fans for both of the above. Therefore, do not leave the disk enclosure
with one of the power supplies removed. Doing so causes the disk
drive temperature to rise, which may significantly decrease the reliability.

When the AL-PA switches of the left and right adapters are set differently, the
FAULT LEDs on the adapters blink and the additional disk enclosure is not started.
If different values are set for the AL-PA switches, turn off the power of the system
including the additional disk enclosure, re-set the AL-PA values properly, and turn
on the power again.

When replacing the adapter due to failure and others, make sure that the AL-PA
switches of the left and right adapters are set to the same values before installation. If
different values are set, a link failure may occur in the worst case.

(6) DE-DIAG ID switch

The DE-DIAG ID switch sets the DE-DIAG address of the disk enclosure.

Set "0" for all the DE-DIAG IDs of the adapters installed in the disk enclosure that is
connected with the standard controller in the array controller via the FC cable
(HSSDC).
If an additional control card (NF2300-SP02E) is installed in the array controller, set
"1" for all the DE-DIAG IDs of the adapters installed in the disk enclosure that is
connected with the additional control card via the FC cable (HSSDC).

The DE-DIAG ID switch is factory-set to "0".

(7) DE-DIAG connectors

To connect the additional disk enclosure (NF2300-SE41E) to the disk array unit,
make the following connections:

• From the PORT1 connector of adapter "0" (ADP0) installed in the disk enclosure
of the disk array unit to the PORT0 connector of adapter "0" (ADP0) installed in
the additional disk enclosure

• From the PORT1 connector of adapter "1" (ADP1) installed in the disk enclosure
of the disk array unit to the PORT0 connector of adapter "1"(ADP1) installed in
the additional disk enclosure

For each of the above connections, use the DE diagnosis cable provided with the
additional disk enclosure or the DE diagnosis cable of separately priced DE cable
(NF9120-SJ04E).

(8) DIAG READY LED (DRDY LED) (green)

The DIAG READY LED lights green when the disk enclosure becomes ready for
diagnosis.

5.3 Connection of Power Cords

WARNING

 Do not concentrate power cords only to some AC outlets. If so, fire may

occur.

 Do not connect the plug of a power cord to an AC outlet with a wet hand. If

so, you may be electrically shocked.

 Do not put a heavy substance on a power cord. If so, the coating of the

power cord may be broken, fire may occur, and/or you may be electrically
shocked.

Be sure to use the power cords provided with the additional disk enclosure or
NEC-specified power cord.

The additional disk enclosure has the redundant power configuration to prevent the entire
unit from shutting down due to a single failure. Therefore, connect two power cords to
both power supplies of disk enclosure when operating the additional disk enclosure.

Connect the power cords in the following procedure.

(1) Check of power supply

Check that the power switch of the additional disk enclosure is set to OFF.

6. ADDITION OF OPTIONAL DEVICES

6.1 Addition of Disk Drive

CAUTION

 Do not store the product in an area where the temperature may increase

extremely or the difference between the warm and cold states is
considerably large. In addition, do not store the product in an area with
much moisture or dust.

 Note that foreign substances such as water and metal may not be entered

into the product during storage. Failure to follow it may cause device
failure, electric shock, and/or fire to occur.

 Keep the product into the package during storage or shipment.

The additional disk enclosure is not normally equipped with disk drives. Before using the
additional disk enclosure, install disk drives sold separately in the additional disk
enclosure. (The additional disk enclosure can be equipped with up to 15 disk drives.

Product name Part number Capacity
Additional disk drive NF2300-SM412E 36GB / 10,000 rpm
Additional disk drive NF2300-SM413E 73GB / 10,000 rpm
Additional disk drive NF2300-SM414E 147GB / 10,000 rpm
Additional disk drive NF2300-SM422E 36GB / 15,000 rpm

 If an additional disk drive and standard disk drive are reassigned to the

same logical disk, all the current data is initialized.
Be sure to make backup copies of necessary data before performing the
addition procedure.
To use additional disk drives for expansion, install them sequentially from
left to right of the disk enclosure.

 An additional disk drive can also be used as a disk drive for a spare disk.

In this case, be sure to install the additional disk drive in slot 14 of the disk
enclosure. If slot 14 already contains a disk drive for a spare disk, install
the additional disk drive in slot 13.

- 27 -

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.

Location label

- 28 -

(2) Removal of dummy tray

Pull the ejector on the dummy tray toward you to release the lock. A click occurs
when the lock is released.

If the lock is released, hold the handle and pull out the dummy tray.

 Be sure to keep removed dummy trays in the designated place.
 After removing an additional disk drive from the unit, be sure to install a

dummy tray into the slot. If using the unit without a dummy tray being

installed, cooling effect on the disk drives lowers and causes heat

generation. Heat generation increases the failure rate, and at its worst it

may cause data loss.

- 29 -

(3) Installation of disk drive

With the ejector of the disk drive opened, engage the guides on the top and bottom
faces of the disk drive with the guide grooves on the disk enclosure and insert the
disk drive to the end.

After the disk drive is inserted to the end securely, push down the ejector opened
upward to click for locking.

When inserting the disk drive into the disk enclosure, push it as far as it will
go and then lock the ejector.
Incorrect insertion may cause malfunction.

The disk array unit cannot use the disk drive only if the disk drive is installed
additionally. Provide the proper setting for the disk drive by using the "NEC
Storage Manager" feature of the disk array unit or contact the service
engineer of the maintenance service agent with the expert knowledge.

- 30 -

(4) Writing information on option label

To allow the options installed in the disk enclosure to be found by external view, the
label indicating the options available for the installation is put on the additional disk
enclosure.

If a disk drive is added, write down the last two digits of model number and a check mark
at the corresponding field on the label to indicate the addition as shown in the figure
below.

Enter the last two digits of model number
("13" in the example).

Note: The figure above indicates that a single NF2300-SM413E is installed at

location '00' in NF2300-SE41E.

If NF2300-SM412E is added, enter the last two digits of model number ("12")

in "NF2300-SM4 (E)" field. Write down a check mark at the location in
which the disk drive is installed, which appears in the area to the right of the
model number field.
Similarly, if NF2300-SM413E or NF2300-SM422E is added, enter the last two
digits of model number ("13" or "22") in "NF2300-SM4 (E)" field. Write
down a check mark at the location in which the disk drive is installed, which
appears in the area to the right of the model number field.
If disk drives are installed at locations '00' and '01,' write down check marks
at the '00' and '01' fields.

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.

It is recommended that important files are backed up to magnetic tapes. This
enables the damage to be minimized in case of emergency including sudden
vibration or shock and power shutdown caused by power interruption.

- 32 -

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.

- 33 -

[Power-on procedure]

Turn on the power switches in the following order (1) to (3):

(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.)

(3) Host system

- 34 -

(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

5. Turn off the shut down switch (toggle switch with SHUT DOWN indicated) of
the LAN card in the array controller. (*3)

- 35 -

*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.

- 37 -

[Power-off procedure]

Turn off the power switches in the following order (1) to (5):

(5) Power switches of disk enclosures

(May be turned off at the same time the power
switches of array controller are turned off.)

(1) Host system

(2) (3) Shut down switches

(4) Power switches of 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.

8. ACTION TAKEN AT OCCURRENCE OF FAULT OR ERROR

The user may remove a defected component and a new component for the
replacement depending on the description in this chapter. However, if so,
NEC does not assume the responsibility for any damage of the additional disk
enclosure and components and any influence resulting from the operation of
the additional disk enclosure. NEC recommends that you ask your
maintenance engineer of the maintenance service agent with expert
knowledge on details of the additional disk enclosure to remove any defected
component and install a new component.

For the installation of two or more disk drives or the change of disk drive
installation positions, perform the job for the disk drives one by one. The
change of disk drive installation positions with any logical disks assigned may
cause some data to be lost.

WARNING

If a trouble including smoking and bad smell occurs or a fault such as halting
of two or more cooling fans is found, turn off the power and disconnect the
power plugs from the AC outlets. Then ask your sales agent or maintenance
engineer to inspect and repair the additional disk enclosure immediately.
Using the additional disk enclosure as it is may cause electric shock or fire to
occur. The user must never repair the additional disk enclosure because it is
dangerous.

CAUTION

 Note that your fingers may not be caught or hit on some object when your

hands are entered into the additional disk enclosure.

 If a fault occurs in the additional disk enclosure, the SERVICE LED on the

additional disk enclosure, the FAULT LED on the defected component, or
the POWER FAULT LED goes on. If a fault occurs, contact your
maintenance engineer of the maintenance service agent with expert
knowledge or prepare the proper maintenance component and replace the
defected component immediately.

 Perform the replacement job as quick as possible. Do not operate the

additional disk enclosure for a long time in the state that one or more
existing disk drive, power supply, or adapter is removed. Failure to follow it
may cause a fault to occur.
If you find the occurrence of an abnormal state such as smoking or bad
smell, turn off the power and pull out the power plugs from AC outlets. Ask
your maintenance service agent for inspection and repair immediately.
