HP Virtual Connect 4Gb Fibre Channel Module for c-Class BladeSystem - Manual (Page 173)

Virtual Connect server profiles 173
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.
Access this screen in one of the following ways:
• Click WWN Settings under Fibre Channel Settings in the left navigation tree.
• Select Fibre Channel Settings from the Configure pull-down menu.
Serial Number Settings screen
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.
