HP Virtual Connect 4.20 Release Notes

Issues and workarounds 7
HP recommends customers with an ME environment upgrade from VC 2.xx to an intermediate firmware
version, such as VC 3.70 or VC 4.10, and then upgrade to VC 4.20.
Issue
VC shows a profile pending when a VC module is removed and inserted.
Workaround
The customer must power cycle the server in a maintenance window to clear the status.
Issue
A server using an HP FlexFabric 20Gb 2-port 630FLB/630M Adapter and configured to use Ethernet Jumbo
frames may experience lower FCoE throughput if server traffic is oversubscribed(that is more than 20Gb)
over the FlexFabric Adapter port and the server is only reading disks without writing them. This is because of
Ethernet traffic consuming excess bandwidth.
Workaround
Configure the server to use standard 1500 byte MTU frames. Alternatively, ensure that server traffic
(FCoE + Ethernet) doesn’t oversubscribe the port bandwidth of 20Gb.
Issue
If a single server is passing FCoE traffic and port monitoring is enabled, the FCoE traffic rate can drop
significantly.
Issue
The VCM GUI does not redirect to the correct IP after a VC failover.
Workaround
The next failover succeeds without any issues. Refreshing the browser or closing and opening a new
session redirects the browser to the correct IP address.
Issue
Errors are received when changing an FCoE network to a different module in a VCEM environment.
Workaround
The customer must revert the changes, and then complete or cancel the domain maintenance mode. If
the uplink must be changed to a different module, the customer can delete the existing network, and
then re-create the network with the same name, but use different uplinks.
Issue
After configuring LDAP authentication, users logging in that do not have Domain role permissions receive an
error when attempting to access the Local Users page. The error is only a notification because Local Users
settings cannot be modified by users who do not possess Domain role permissions.
Issue
If an HP ProLiant BL870c i2 Server is present in bays 3 and 4 of a C3000 enclosure, then the Hardware
Overview page in VC Manager does not display the correct graphical picture of the server. VC Manager
manages the server properly. It is only the graphical image that is incorrect.
Issue
In a VC domain with a VC profile assigned to a HP ProLiant BL2x220 Server Blade, when the I/O module
connected to the dual-technology port is replaced with a module using single-blade technology, the OA
