HPE MSA Replacement Instructions Manual

HPE MSA Controller
Module Replacement

About this document

• The SMU (Storage Management Utility) and the CLI
can be used to manage the enclosure. Tasks in this
document demonstrate using the SMU. Refer to the
SMU reference guide, or the CLI reference Guide for
instructions using those interfaces.

Before you begin

Observe the following:

CAUTION:

• Removing a module from an operational
enclosure significantly changes air flow within
the enclosure. Openings must be populated for
the enclosure to cool properly. Leave modules
in the enclosure until a replacement is
available.

• Parts can be damaged by electrostatic
discharge; use proper anti-static protection.
Keep parts in electrostatic containers until
needed and ensure you are properly grounded
when touching static-sensitive components.

IMPORTANT:

When replacing both controllers in an operational
enclosure, do as follows:

1. Replace one controller as detailed in these
instructions.

2. Wait 30 minutes. This pause ensures that the
controller and its ownership of the vdisks or
disk-groups have enough time to fully stabilize.

3. To ensure that the system is stable, check the
system status and event logs.

4. Replace the other controller as detailed in these
instructions.

IMPORTANT:

When two controllers are installed in an enclosure,
they must be the same model and the same
firmware version. Mixing controller types or
firmware versions in the same enclosure is not
supported.

To reduce the impact on system performance, perform
all maintenance tasks during periods of low system
activity or during a system maintenance window.

Note key settings using the SMU: Consult the SMU
guide for your model to determine how to obtain these
settings.

The following illustration shows controller module
locations.

representations of modules and enclosures;
procedures are the same for all modules shipped
with this document.

Verifying module failure

Before replacing the module, look at the event log,
system management utilities, and device LEDs, to
confirm that the module has failed.

Partner Firmware Update (dual-controller
configurations only)

Module LED Description

FRU OK

Fault/Service
Required

• Solid Green = Module is operating
normally

• Blink = System is starting up

• Off = Module is not operating
normally

• Solid Amber = Fault condition

• Blinking Amber = Hardware­controlled power-up or cache flush/
restore error

• Off = No fault conditions

Recording configuration settings

As a best practice, record system settings before
replacing a controller module.

In a dual-controller configuration, the Partner Firmware
Update option ensures that both controllers have the
most recent version. For controller replacement on an
MSA P2000 array, Hewlett Packard Enterprise
recommends disabling this feature to avoid
unintentionally changing the firmware on the controller
not being replaced. For all other MSA arrays Hewlett
Packard Enterprise recommends leaving this setting
enabled during controller replacement.

After both controllers are running the desired firmware
version, Hewlett Packard Enterprise recommends
enabling this feature for future firmware upgrades. For
the MSA2040/1040 and MSA2050/1050 arrays, it is
highly recommended to have this setting enabled at all
times.

Update setting.
