About this document

This document details procedures for replacing a failed MSA1500

or MSA1510i chassis. When replacing a chassis, components are

removed from the failed chassis and then installed in the replacement.

Components that are moved include the following:

•Fibre Channel (or Ethernet) I/O modules

•Fan modules

•SCSI I/O modules

•Power supply modules

•Controllers

•Blanks

NOTE:

The MSA1500 connects to the SAN with a Fibre Channel I/O

module and the MSA1510i connects to the network with a 2–Port

Ethernet I/O module. Illustrations in this document show the Fibre

Channel I/O module of an MSA1500. If you are replacing an

MSA1510i chassis, your module will look different.

Before youbegin

Read the following cautions and notices before replacing the chassis.

CAUTION:

Parts can be damaged by electrostatic discharge. Use proper

anti-static protection. For additional information, see the

documentation that shipped with your system.

CAUTION:

Be sure to follow these instructions carefully. If the procedures are

done improperly or out of sequence, it is possible to lose data

or damage equipment.

IMPORTANT:

Schedule a maintenance window of approximately 60 minutes to

complete this procedure.

IMPORTANT:

Before beginning these procedures, verify that there is a known,

good backup of the system. Backup all volumes and, for the

MSA1510i, record the iSCSI and Management settings.

TIP:

Before beginning these procedures, label all cables. This ensures

that they are reconnected correctly.

Removing the failed chassis

Prepareforthereplacement

1. If the MSA is operational, stop all access to the MSA.

2. Press and hold the power on/standby button for ﬁve seconds to

place the MSA in standby.

3. Label each cable carefully and then disconnect all of the cables.

CAUTION:

If replacing the MSA1500 chassis, use caution when handling

the Fibre Channel cables:

•Touching the end of a Fibre Channel cable will either

damagethecableorcauseperformanceproblems,including

intermittent difﬁculties accessing the storage.

•When a Fibre Channel cable is not connected, replace the

protective covers on the ends of the cable.

Remove the Fibre Channel (or Ethernet) I/O

modules

1. Lift the port-colored latch and pull the module out of the chassis.

NOTE:

The following illustration demonstrates removing a Fibre Channel

I/O module from the MSA1500 chassis. For the MSA1510i, the

2–Port Ethernet iSCSI I/O module is in this slot.

15498

2. Remove the other I/O module or blank.

Remove the fan modules

1. Lift the port-colored latch and pull the module out of the chassis.

15643

2. Remove the other fan module.

Remove the SCSI I/O modules

1. Lift the port-colored latch and pull the module out of the chassis.

15644

2. Remove all other SCSI I/O modules or blanks.

Remove the power supply modules

1. Press the port-colored latch towards the side of the module and pull

the module out of the chassis.

15645

2. Remove the other module.

Remove the controllers

1. Press the controller thumb latch to release the latch handle, and

then rotate the latch handle out.

15492

2. Grasp the latch handle and pull the controller out of the chassis.

3. Remove the other controller or blank.

Remove the MSA from the rack

1. RemovethedecorativebezelfromthefrontoftheMSAbygrasping

the outside edges and pulling with sufﬁcient force to disengage

the retaining clips.

15642

2. Loosen the thumbscrews securing the MSA to the front of the rack,

and then slide the MSA out of and away from the rack.

Installing the replacement chassis

Record the serial numbers of the two chassis

IMPORTANT:

Depending on the MSA model and ﬁrmware version, the serial

number of the original chassis may automatically be transferred

to the replacement chassis. For continued service and support

from HP authorized service personnel, the serial number of the

original chassis must also be physically recorded on the label of

the replacement chassis.

The product label is located on the side of the MSA chassis.

15641

Install the MSA intherack

1. Slide the MSA intotherack,andthensecuretheMSAtothefront

of the rack, using the thumbscrews on the front of the MSA.

2. Attach the decorative bezel on the front of the MSA by aligning

the pins and retaining clips on the back of bezel with the

corresponding locations on the front of the chassis. Then, with even

pressure, push ﬁrmly on the bezel until the retaining clips engage.

15649

Install the controllers

1. Press the controller thumb latch and rotate the latch handle out.

15493

2. Slide the controller into the chassis and then push ﬁrmly to ensure

agoodseat.

3. Rotate the latch handle inward, pressing until it is ﬂush against

the front panel.

4. Installtheothercontrollerorblank.

Install the power supply modules

1. Slide the module into the chassis power supply slot until the latch

clicks into place.

15646

2. Install the other module.

Page 3

Install the SCSI I/O modules

1. Slide the module into the chassis SCSI I/O slot until the latch clicks

into place.

15647

2. Install all other SCSI I/O modules or blanks.

Install the fan modules

1. Slide the module into the chassis fan slot until the latch clicks into

place.

15648

2. Install the other fan module.

Install the Fibre Channel (or Ethernet) modules

1. Slide the module into the chassis network interconnect slot until

the latch clicks into place.

NOTE:

The following illustration demonstrates installing a Fibre Channel

I/O module in the chassis. For the MSA1510i, the 2–Port

Ethernet iSCSI I/O module is in this slot.

15502

2. Install the other I/O module or blank.

Completing the replacement

1. Reconnect the AC power cords to the MSA.

2. Reconnect the SCSI and Fibre Channel (or Ethernet) cables to the

MSA chassis.

IMPORTANT:

When connecting SCSI and Fibre Channel (or Ethernet) cables,

make sure that the connections are secure and are connected

inthesameconﬁguration as before the replacement. Do not

make any conﬁguration changes at this time. If the conﬁguration

differs, the MSA will not properly see and identify the storage.

3. Start up the following devices and wait for them to complete their

startup routines:

• Uninterruptible Power Supplies

• Network switches

• External storage enclosures

4. Start up the MSA1500/1510i.

5. Read the controller LCD panel messages during the MSA startup

routine.

• If the following messages are displayed, the serial number

of the original chassis was automatically transferred to the

replacement chassis.

SPARE CHASSIS DETECTED

CHASSIS SERIAL NUMBER FLASHED UPDATED

IMPORTANT:

If these messages are displayed, the MSA1500/1510i will

automatically restart.

• If the following message is displayed, it may safely be ignored.

I2C WRITE FAILURE

• When the following message is displayed, the startup routine is

complete.

STARTUP COMPLETE

Verifying proper operation

After replacing the failed chassis, verify that:

•No error messages are displayed on the controller LCD panels.

•The chassis Power LED is solid green.

•The chassis Heartbeat LED is blinking green.

•LEDs on each MSA module are showing a healthy status.

IMPORTANT:

If CHASSIS MISMATCH POWER OFF AND FIX is displayed

on the controller LCD panel, persistent data stored on all of the

hard drives does not match. The original conﬁguration was

changed or startup procedures were followed incorrectly. Power

off the MSA1500/1510i, correct any conﬁguration changes, and

repeat the power-on sequence.

Returning the failed chassis

In the materials shipped with the replacement, HP speciﬁes whether

the defective component must be returned to HP. In cases where it is

required, you must ship the defective part back to HP within a deﬁned

period of time, normally ﬁve business days. The defective part must be

returned with the associated documentation in the provided shipping

material. Failure to return the defective part may result in HP billing you

for the replacement. For details, follow the return instructions shipped

with the replacement chassis.
