Configuring the Virtual Connect domain using the CLI 81

boot environments and host operating system software as the hardware addresses. To use administered

MAC addresses, select a range of HP pre-defined or user-specified MAC addresses.
Be sure to review the following list of guidelines before creating and deploying server profiles:

The server blade firmware and option card firmware must be at a revision that supports Virtual
Connect profile assignment. See the HP website (

http://www.hp.com/go/bladesystemupdates

).

Before creating the first server profile, select whether to use moveable, administered MAC addresses
and WWNs or whether to use the local server blade factory default MAC addresses and WWNs.

After an enclosure is imported into a Virtual Connect domain, server blades remain isolated from the
networks and SAN fabrics until a server profile is created and assigned.

Server blades must be powered off to receive (or relinquish) a server profile assignment when using
Virtual Connect-administered MAC addresses, WWNs, or changing Fibre Channel boot parameters.

FC SAN Connections are only shown in server profile screens when there is an HP Virtual Connect
Fibre Channel Module in the enclosure managed by Virtual Connect. FC SAN Connections are

added in pairs and cannot be deleted. If an HP Virtual Connect Fibre Channel Module is added to a

Virtual Connect domain that has existing profiles, an option to add FC connections appears in the

existing profiles when editing.

Some server profile SAN boot settings (controller boot order) are only applied by Virtual Connect

after the server blade has been booted at least once with the final mezzanine card configuration.

If PXE, controller boot order, or SAN boot settings are made outside of Virtual Connect (using RBSU
or other configuration tools), Virtual Connect will restore the settings defined by the server profile

after the server blade completes the next boot cycle.

If using a QLogic HBA with some versions of Linux (RHEL3, RHEL4, SLES9, and SLES10), the HBA

connection type must be set to "point to point only" in the adapter configuration settings in the
QLogic BIOS utility or QLogic OS utility (if available). If the HBA settings are not changed, the HBA

may be unable to log into the fabric and discover devices on the SAN.

Server profiles are associated with a specific enclosure device bay. After a profile is assigned, the Virtual

Connect Manager configures the server blade in that device bay with the appropriate
MAC/PXE/WWN/SAN boot settings and connects the appropriate networks and fabrics. Server blades

that have been assigned a profile and remain in the same device bay do not require further Virtual

Connect Manager configuration during server or enclosure power cycle. They will boot and gain access

to the network and fabric when the server and interconnect modules are ready.
If a server blade is inserted into a device bay already assigned a server profile, Virtual Connect Manager

automatically updates the configuration of that server blade before it is allowed to power up and connect

to the network.
If a server blade is moved from a Virtual Connect managed enclosure to a non-Virtual Connect enclosure,
local MAC addresses and WWNs are automatically returned to the original factory defaults. This feature

prevents duplicate MAC addresses and WWNs from appearing in the data center because of a server

blade redeployment.

NOTE:

If you are using server factory default MAC addresses WWNs and default Fibre

Channel boot parameters, you do not have to power off a server to make any profile changes.

If you are using HP assigned or user assigned MAC addresses or WWNs, you must power a

server off when moving a profile to the server or away from the server.
