•
Breaking the Virtual Connect lock by using the VC command line. To resolve this issue, remove
the VC Domain from the VC Domain Group.
•
Virtual Connect fails to respond. If the VC Domain Maintenance job fails due to poor or failed
VC communication, fix the communication issue and complete VC Domain Maintenance again.
Using VLAN capacity
CAUTION: Virtual Connect Manager implemented with firmware version 3.3x 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 Virtual Connect
Manager.
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 Virtual Connect 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 8Gb 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 4Gb FC module replaces an HP Virtual Connect 8Gb 24-port FC
module.
•
An HP Virtual Connect 8Gb 24-port FC module replaces a HP Virtual Connect 4Gb FC module.
•
If HP Virtual Connect 8Gb 24-port FC modules and HP Virtual Connect 4Gb FC modules share
the same I/O bay slice. (For example, a HP Virtual Connect 4Gb FC module in I/O Bay 3
and a HP Virtual Connect 8Gb 24-port FC module in I/O Bay 4).
•
In a multienclosure VC Domain, if there are mixed HP Virtual Connect 4Gb FC modules and
HP Virtual Connect 8Gb 24-port FC modules in the same I/O bay from different enclosures.
(For example, 4Gb FC modules in the local enclosure, but 8Gb 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 Virtual Connect Manager.
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.
