HP Virtual Connect Enterprise Manager 7.2 Release Notes

Enable the VC domain Maintenance operation.a.

b. Upgrade the managed VC domain to (at least) the minimum VCEM supported VC firmware

version.

c. Complete the VC domain Maintenance operation.

2. For each VC Domain Group marked with an 'incompatible firmware' status: Upgrade the VC

Domain Group firmware mode to (at least) the minimum supported by VCEM.

In order to update the VC domain firmware version, you must check the HP Insight Management

Support Matrix for VCEM supported VC firmware versions.

Managing VC domains with Expanded VLAN capacity enabled

VCEM 7.1.1 or later is able to manage VC domains with Expanded VLAN capacity enabled.

CAUTION: Virtual Connect Manager 3.30 or later does not allow you to easily revert back from

Expanded VLAN capacity mode to Legacy capacity mode. To revert back to Legacy capacity

mode, you must delete the VC domain in Virtual Connect Manager and then recreate it.

Using Expanded VLAN capacity

Virtual Connect Manager 3.7x or later has Expanded VLAN capacity mode enabled by default.

To add a VC Domain with VC FW 3.7x to a VC Domain Group prior to VC firmware 3.7x, the

VC Domain Group must have Expanded VLAN Capacity enabled.

NOTE: If the VC Domain Group was created with all VC Domains in Legacy VLAN Capacity

and the VC firmware is prior to 3.7x (3.30/3.51/3.60), when you update the VC firmware to

3.7x (3.70/3.75) or later, all VC Domains will continue in Legacy VLAN capacity.

Using Expanded VLAN capacity with the Cancel VC domain Maintenance operation

Cancelling maintenance mode in VCEM will not revert the Expanded VLAN capacity configuration

back to Legacy capacity mode.

If you enable Maintenance Mode, change Legacy capacity to Expanded VLAN capacity, and then

click Cancel VC domain Maintenance, VCEM cannot revert back to Legacy capacity mode in the

VC domain. Instead, the VC domain displays the “Under maintenance” icon and VCEM fails to

complete or cancel the maintenance operation. To resolve this, see the procedure to delete the

domain in “Using Expanded VLAN capacity ” (page 8).

Adding a VC 3.70 or later Domain with IGMP No Flood enabled into a VC Domain

Group with group firmware mode 3.3x or 3.5x

IMPORTANT: IGMP behavior is configured by using Advanced Settings in the VCM GUI. VCM

3.70 allows administrators to select whether IGMP Snooping is enabled and whether to prevent

flooding of unregistered multicast traffic. These settings can be viewed in the Ethernet Common

Settings section of the VC Domain Group Properties or the VC Domain Properties displayed in

VCEM.

VCEM is unable to communicate to a VC Domain running VC firmware 3.70 after VCEM attempts

to configure the VC Domain using Prevent flooding of unregistered multicast traffic with a VC

Domain Group that disables the IGMP Snooping feature.

NOTE: This does not impact server blade I/O connectivity in the managed enclosures.

After the situation occurs, the VCEM job reports the failure immediately following the entry “Validated

VC Domain.” It contains the following message:

Error during Add VC Domain [xxxxx_vc_domain] to VC Domain Group.

Details: Virtual Connect is not responding. To resolve this issue:

1. Verify if the IP address is active (try to log to the Virtual Connect Manager via Onboard Administrator).

2. Verify that there are no network related issues between Virtual Connect Manager and VCEM (try to ping from
