HP Virtual Connect 1.10Gb-F Ethernet Module for c-Class BladeSystem - Manual (Page 77)

HP Virtual Connect Manager 77
If using Virtual Connect assigned MAC addresses, the following notes apply:
• Virtual Connect automatically reserves both a primary address and an iSCSI MAC address for use
by multifunction gigabit server adapters, such as the HP NC373m PCI Express Dual Port
Multifunction Gigabit server adapter. Only the primary MAC address is used by standard (not
multifunction) Ethernet devices.
• If a server blade is moved from a Virtual Connect managed enclosure to a non-Virtual Connect
enclosure, the local MAC addresses on that server blade are automatically returned to the original
factory defaults.
If a server blade is removed from a bay within a Virtual Connect domain and installed in another bay in
the same Virtual Connect domain or in a bay in a different domain, it is assigned the new set of
addresses appropriate for that server location.
Assigned MAC addresses
The MAC address range used by the Virtual connect domain must be unique within the environment. HP
provides a set of pre-defined ranges that are for use by Virtual Connect Manager and will not conflict
with server factory default MAC addresses.
When using the HP-defined MAC address ranges, ensure that each range is used only once within the
environment.
