HP Virtual Connect 8Gb 24-port Fibre Channel Module for c-Class BladeSystem - Manual (Page 141)

Configuring the Virtual Connect domain using the CLI 141
CAUTION: To avoid storage networking issues and potential loss of data associated with
duplicate WWNs on a FC SAN fabric, plan carefully when allowing Virtual Connect to assign
server blade WWNs so that the configured range of WWNs is used only once within the
environment.
The WWN range used by the Virtual Connect domain must be unique within the environment. HP provides
a set of pre-defined ranges that are reserved for use by Virtual Connect and do not conflict with server factory
default WWNs.
When using the HP-defined WWN ranges, be sure that each range is used only once within the environment.
To configure WWN address ranges, use the set domain command:
• VC-defined
>set domain WwnType=VC-Defined WwnPool=5
• Factory default
>set domain WwnType=Factory-Default
Creating FC fabrics
To create an FC SAN fabric and add it to the domain, use the add fabric command:
>add fabric MyFabric2 Bay=3 Ports=1 Speed=2Gb
Displaying FC fabrics
To display a list of all FC SAN fabrics, use the show fabric command:
>show fabric
Serial number settings
The serial number settings feature enables you to add a serial number and UUID to server profiles. The UUIDs
that Virtual Connect assigns are randomly generated. A UUID pool is not required.
By configuring VCM to assign serial numbers, a profile can present a single serial number regardless of the
physical server. With these configuration values added to server profiles, software that is licensed to a
particular server, based on one or both of these values, can be migrated to new server hardware without
re-licensing the software for the new server hardware. This feature prevents you from having to reinstall serial
number sensitive software after a system recovery.
If you need to access the physical serial number of a server blade, the Onboard Administrator displays both
the physical and assigned serial numbers.
After server profile creation, the following guidelines apply:
• Serial numbers can be changed from factory default to VC-assigned.
• Factory default serial numbers cannot be changed.
• User-defined serial number ranges can be expanded.
• User-defined serial number ranges cannot be reduced.
