Using VLAN capacity
CAUTION: VCM firmware versions 3.3x through 3.6x 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 VCM.
VC firmware 3.7x removes support for legacy VLAN capacity. All VC domains with VC 3.7x
installed support "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, VLAN capacity will continue in Legacy mode.
Before applying Expanded VLAN capacity to a VC Domain 3.3x or later during Maintenance
Mode, make sure the VC Domain Group that the VC Domain belongs to is running firmware mode
3.3x or higher (this is a VCEM rule). If you change a VC Domain 3.3x to Expanded VLAN Capacity
and the VC Domain Group firmware mode is lower than 3.3x, the Complete Maintenance Mode
operation will fail, because VCEM will detect an enabled feature (Expanded VLAN capacity) not
supported by the other VC Domains (with older firmware). The VC Domain will remain in
Maintenance Mode status and VCEM will not be able to complete or cancel the maintenance
operation. To complete or cancel the maintenance operation, you must first remove the VC Domain
with Expanded VLAN capacity from the Domain Group.
Working with HP Virtual Connect 8 Gb Fibre Channel Module for c-Class BladeSystem
VCEM cannot manage a VC Domain having one or more FC modules in an Incompatible state.
The FC module can become incompatible in the following situations:
•
An HP Virtual Connect 4 Gb FC module replaces an HP Virtual Connect 8 Gb 24-port FC
module.
•
An HP Virtual Connect 8 Gb 24-port FC module replaces a HP Virtual Connect 4 Gb FC
module.
•
If HP Virtual Connect 8 Gb 24-port FC modules and HP Virtual Connect 4 Gb FC modules
share the same I/O bay slice. (For example, a HP Virtual Connect 4 Gb FC module in I/O
Bay 3 and a HP Virtual Connect 8 Gb 24-port FC module in I/O Bay 4).
•
In a multienclosure VC Domain, if there are mixed HP Virtual Connect 4 Gb FC modules and
HP Virtual Connect 8 Gb 24-port FC modules in the same I/O bay from different enclosures.
(For example, 4 Gb FC modules in the local enclosure, but 8 Gb FC modules in the remote
enclosures.)
Adding or removing remote enclosures from a multienclosure domain in VC Domain
Maintenance
NOTE: Adding enclosures that are not yet licensed in VCEM causes that VC Domain to be put
in Not Licensed status. You must either license or remove the newly added enclosure.
To add or remove remote enclosures:
1.
Select the VC Domain that must be changed, and put it into maintenance mode.
2. Access VCM.
3. Click Domain Settings
→Domain Enclosures.
4. Find and import the enclosures to be added, or delete the enclosures to be deleted.
5. From VCEM, complete VC Domain Maintenance.
