Mixed VC firmware versions and compatibility in a VC Domain Group
VCEM enables firmware compatibility using current and future versions of VC firmware. This feature
provides both backward and forward VC firmware compatibility.
Backward compatibility for VC firmware
You can install VCEM 7.1 and run the latest VC firmware in a VC Domain Group that has an
earlier but supported firmware mode.
IMPORTANT:
The minimum supported firmware version in VCEM 7.1 is VC firmware 3.15. If
you are upgrading from an earlier VCEM version managing VC Domains that have a VC firmware
version older than 3.15, VCEM will mark those VC Domains and VC Domain Groups with an
incompatible firmware status.
You must upgrade the VC Domain firmware and the VC Domain Group firmware mode to 3.15
or later before you can manage those VC Domains and VC Domain Groups with VCEM 7.1.

VC 3.30 features must be disabled from VC Domains to be in the same group as VC 3.15.

If enhanced VLAN capacity is enabled for the VC Domain being added to a VC Domain Group, the VC Domain group
must also have enhanced VLAN capacity enabled.

For the VC firmware version, HP recommends 3.18 (instead of 3.15) but the Virtual Connect Domain Group firmware
mode is displayed in the VCEM GUI (Virtual Connect Domain Group details) as 3.15.
Forward compatibility for VC firmware
VCEM enables firmware compatibility using current and future versions of VC firmware. For
example, VCEM 7.1 can support future VC firmware versions (when available) in compatibility
mode. This depends on the firmware mode of the VC Domain Group you are trying to add the VC
Domain with the newer VC firmware version into. See
“Backward compatibility for VC firmware
and
“Performing the VC Domain maintenance operations with forward-compatible
for more information.
Selecting HP Virtual Connect Enterprise Manager ports
Before you install VCEM, check
to ensure you have the correct ports open
to allow communication.
