MAC, WWN, and Serial Number management
You must verify that VC Domains within a network have unique MAC addresses, WWN addresses,
and serial numbers. Adding a VC Domain to a VC Domain Group or creating a VC Domain Group
does not verify that the profiles in a VC Domain use MAC or WWN addresses allocated in the
VCEM external address pool. You can overwrite the external addresses to become in use status.
To prevent external addresses from use in VCEM, add the addresses to the exclusion addresses
pool. If you plan to add the VC Domain back to VCEM, then you must also remove these addresses
from the exclusion addresses pool.
Duplicate MAC and WWN address assignments
Use of Virtual Connect Enterprise Manager (VCEM) 6.2 or 6.2.1 may result in duplicate MAC and
WWN address assignments. This will occur if a Virtual Connect profile edit fails when removing
iSCSI or FCoE connections via the VCEM Graphical User Interface (GUI). The VCEM 6.2.2 or later
upgrade contains a critical fix and is strongly recommended to prevent this issue.

Adding or removing VC modules to VC Domain Group Configuration
To add or remove VC modules to all VC Domains managed by a VC Domain Group:
Procedure 2
1.
Go to VCEM, click the VC Domain Groups tab, select the desired VC Domain Group where
you want to add or remove VC modules, and then click Delete. For more information, see the
“Deleting a VC Domain Group” (page 67)
.
2.
For each VC Domain released from the VC Domain Group, insert or remove VC modules in
the corresponding enclosure, and perform the necessary domain, network, and storage
configuration changes in the Virtual Connect Manager user interface.
Before VC module removal, remove the VC module uplink ports from all existing Network or
Shared Uplink settings from VC Domain configuration.
For VC module removal, from the VC Manager user interface, click Hardware
Overview
→Enclosure_Name→Interconnect Bays, select the VC module at the bay you want
to remove, then click Remove from Domain.
3.
Return to VCEM, click the VC Domain Groups tab, and click New. For more information about
creating a VC Domain Group, see
“Creating a VC Domain Group” (page 42)
. In step 1 of
the creating a VC Domain Group procedure, select the VC Domains to add to the new VC
Domain Group. Wait until the job operation is completed. As a result, the new VC Domain
Group created contains an updated configuration reflecting the new VC modules.
NOTE:
Existing profiles cannot see new FC SAN connections added using these steps. For more
information, see
“Managing server profiles” (page 71)
.
Unauthorized error when trying to access the VCEM home page
VCEM requires the CMS to be correctly registered in the DNS. Make sure Systems Insight Manager
can correctly discover the CMS. You might experience an unauthorized error page when trying
to access the VCEM home page if the CMS is incorrectly registered in the DNS.
To correct this issue, register the CMS in DNS or add the CMS hostname to the Windows hosts
file.
