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.

Remove the MSA from the rack
1. RemovethedecorativebezelfromthefrontoftheMSAbygrasping
the outside edges and pulling with sufficient force to disengage
the retaining clips.

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.

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.

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

Install the power supply modules
1. Slide the module into the chassis power supply slot until the latch
clicks into place.

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.
