Midplane assembly replacement 67
o
Failover the VC domain to the other VC module by using the
reset vcm –failover
command
and retesting the blade.
o
Back up the VC domain configuration by using VCSU or VC GUI.
o
Delete the VC domain and restore the VC domain and retry (the domain could be corrupted causing
a server not to assign a profile correctly).
9.
If an entire row (bottom or top) of fans is not working, then replace the midplane.

If further help is needed, contact HP Support and provide the OA SHOW ALL output.
Midplane assembly
Before replacing the midplane, locate and record the enclosure serial number and part number, using one of
the following methods:
•
Locate the enclosure tag on the front, side, or rear of the enclosure.
•
Access the Onboard Administrator.
•
Log in to the Onboard Administrator CLI and run the command
Show Enclosure Info.
See the
HP
BladeSystem Onboard Administrator Command Line Interface User Guide
for information on accessing
the CLI.
WARNING:
To reduce the risk of damage to the midplane and component connectors, always
remove or disengage and extend all blades and power supplies approximately 8 cm (3 in) before
removing or installing the rear cage.
CAUTION:
The firmware included in Onboard Administrator version 3.20 and later
automatically restores the enclosure identity, including the serial number, PID, and PDU type, if a
midplane assembly replacement is detected. This firmware feature requires that the original
Onboard Administrator modules and all original fans be reinstalled along with all power supplies
before installing any other blade or interconnect module. All power supply modules can be
replaced while the enclosure is powered off without affecting the ability of the Onboard
Administrator to automatically restore enclosure identity.
VC, Virtual Connect Enterprise Manager, and Insight Control use the enclosure serial number as
a critical key. If you replace the midplane assembly without ensuring that the serial number is
restored prior to installing the VC modules and server blades, then the VC domain is deleted and
all server network and SAN connections are disabled .
CAUTION:
If you are using a Virtual Connect environment, some of these procedures might
cause the loss of Virtual Connect credentials and the loss of communication between the Onboard
Administrator and the Virtual Connect Interconnect module. Ensure the Virtual Connect
configuration is backed up before proceeding with any of the following procedures. Virtual
Connect configuration can be backed up by using Virtual Connect GUI or Virtual Connect
Support Utility.
Removing the midplane assembly
1.
Power down the blades (such as servers, workstation, storage, and so on).
2.
Power down the enclosure.
NOTE:
Be sure to note the location of each removed component so it can be returned to its
original location after the midplane assembly is replaced.
3.
Disconnect all cables from the enclosure.
