Maintaining a VC Domain from the VC Domain Groups page

IMPORTANT:

VCM 3.3x to 3.6x 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 VCM and then recreate it.

VC firmware 3.7x supports legacy VLAN capacity for VC Domains upgraded to VC 3.7x from
older versions of VC firmware. New domains being created with VC 3.7x or later will automatically
be set to expanded VLAN capacity. When adding a VC 3.7x or later Domain into a VC Domain
Group, you must ensure that the VC Domain Group is configured for "Expanded VLAN Capacity".
This can be done by putting one of the VC Domains in the VC Domain Group into maintenance
mode and configuring "Expanded VLAN Capacity" in VCM. Complete maintenance mode to
propagate this change to all the member VC Domains.

If a VC firmware earlier than 3.7x is running in Legacy mode and it is updated to VC firmware
3.7x, the VLAN Capacity will continue in Legacy mode.

To perform VC Domain maintenance from the VC Domain Groups page:
1.

Select the VC Domain Group on which you want to perform maintenance.

Click VC Domain Maintenance.

NOTE:

When a VC Domain has a status of Under maintenance, VCEM does not allow you

to perform server profile operations in any VC Domains which belong to that VC Domain
Group. You can have a maximum of one VC Domain in the VC Domain Group that has a
status of Under maintenance.

Select the target VC Domain within the selected VC Domain Group which will be enabled for
maintenance, and click Next. The VC Domain Maintenance page appears.

To unlock VCM for domain, network, and storage changes, click Make changes via VC
Manager. The VCM web interface appears in a separate browser window. The under
maintenance status indicates that the VC Domain Group is temporarily unlocked for domain
network and storage.

Using VCM, log in with full user rights at the Virtual Connect Manager prompt and perform
and save the necessary changes. VCEM blocks all operations related to the VC Domain and
to its respective VC Domain Group while the VC Domain is under VC Domain Maintenance.
Close the VCM web browser and return to the VC Domain Groups page in VCEM. To confirm
changes in VCEM, repeat steps 1 and 2.

Click the Restore configuration check box to enable VCEM to automatically restore the original
VC Domain configuration in case changes cannot be applied to the VC Domain Group.

Select from one of the following options:

•

Click Complete VC Domain Maintenance to apply the changes.

If VCEM detects that all VC Domains in the group have higher firmware versions than the
VC Domain Group, a warning similar to the following is displayed:

VCEM detected that in addition to completing the VC Domain

Maintenance process, the VC Domain Group firmware mode [{0}] can
