Software Owner's manual

If the VC Domain firmware is 2.1x or later, perform the following:
• To remove the account and release the VC Domain from VCEM control, from the Virtual
Connect Manager command prompt, enter:
remove external-manager Username=xyz
mactype=<Factory-Default/User-Defined> MacStart=<> MacEnd=<>
wwnType=<Factory-Default/User-Defined> WwnStart=<> WwnEnd=<>
serverIdType=<Factory-Default/User-Defined> serverIdStart=<>
serverIdEnd=<>
NOTE: The option “-quiet” is available to suppress user confirmation prompts. This
option is useful for scripting operations. This option is available for VC firmware 2.1x or
later for the disable account, remove the account, and release ranges commands.
Cannot resynchronize VC Domain that is in Configuration Mismatch state
Attempting to resynchronize a VC Domain that is in Configuration Mismatch results in a failed job,
and the following message appears:
Unable to import the MAC, WWN or VSN addresses. Possible reasons include
1) Address is being used in VCEM.
2) Address conflicts with an existing Exclusion Range.
3) Address does not fall within the defined VCEM Global Range.
To identify why the issue occurred, consider that both VC and VCEM use two MAC addresses for
each Ethernet network connection and two WWN addresses for each Fibre Channel connection.
However, only one of these addresses appears in the user interface. When checking if a server
profile is using an address, you must consider both the displayed address and the hidden address.
When considering the hidden addresses, add 1 to the addresses that are being displayed. For
example, if a profile is using two Ethernet connections with MAC addresses 00-21-5A-9B-00-00
and 00-21-5A-9B-00-02 then the hidden addresses will be 00-21-5A-9B-00-01 and
00-21-5A-9B-00-03. In this example, the profile will be using four MAC addresses from
00-21-5A-9B-00-00 to 00-21-5A-9B-00-03.
To resolve this issue:
1. Access Virtual Connect Manager for the VC Domain that is in Mismatch Configuration state.
2. Verify the server profiles inside the VC Domain searching for MAC, WWN, or VSN (Virtual
Server Number) addresses that are:
• Already in use by VCEM—In this case, delete the server profiles that have addresses that
are reported as in use by VCEM.
• Inside an existing exclusion range in VCEM—In this case, remove the exclusion range or
adjust it so it does not contain the conflicting addresses.
• Outside any range known to VCEM—In this case, create a user defined address range
that contains all the addresses in use by the profiles.
After completing these steps, perform the VC Domain resynchronization operation again.
