NOTE:
While the network mapping has been adjusted to preserve the original mapping of
networks to ports, it is not possible to adjust the MAC address assignment to preserve the same
mapping of MAC addresses to ports. If your OS is HP-UX, see the section
“Preserving VC-assigned
MAC addresses in HP-UX by enabling Portable Image” (page 84)
for a method which can be used
to preserve VC-assigned MAC addresses.
When moving a bladed server to a new enclosure as part of the upgrade where VC-assigned
MAC addresses or WWNs are used, the new enclosure VCM setup must use the same built-in
blocks of addresses. Even when this is done, it may be difficult to define a VC server profile where
the MAC addresses and WWNs are the same as those used on the original server before the
upgrade. If identical MAC addresses and WWNs are required and cannot be obtained using the
pre-defined blocks of addresses on the new enclosure, then the new enclosure will have to be set
for user-defined addresses with the addresses from the original enclosure profile moved into the
new enclosure VC domain. This caution also applies where VC-assigned UUID and serial numbers
are used, but it may not be possible to obtain the same VC-assigned UUID in a new enclosure. It’s
very important that setup for the new enclosure is done carefully so that there are no duplicate
MAC addresses or WWNs on a network. The values moved to a new enclosure should not remain
in use on the original enclosure.
The VC server profile should always be checked after being applied to the upgrade to make sure
that profile connection entries are mapped to ports as expected and to make sure there are no
profile errors or warnings which must be resolved. See the HP Virtual Connect for c-Class
BladeSystem User Guide for more information on VCM server profiles.
Preserving VC-assigned MAC addresses in HP-UX by enabling Portable Image
If your OS is HP-UX where the VC server profile does not use the hardware default MAC addresses
and it is important that Ethernet connections configured in the OS retain their VC-assigned MAC
addresses, then there is a package called “Portable Image” (PI) which can be used. The HP-UX
