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.
• For the latest product documentation, see the HPE
Support Center website http://www.hpe.com/

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.
