Restart after OA credential recovery
For VC v1.21 and higher, the VC Manager behavior has changed for powered-up servers when
restarting after a recovery of OA credentials. In previous versions, the servers entered a "profile pending"
state and required a power cycle to recover. For VC v1.21 and higher, a new state, "profile recovered,"
is applied to servers that are powered on when VC Manager restarts after an OA credential recovery.
When VC Manager detects a restart after a credential recovery, it rewrites the profile parameters for any
server that is powered on, connects the server to the appropriate Ethernet networks and FC fabrics, and
then puts the server and profile in the new "profile recovered" state. The server and profile remain in the
"profile recovered" state until the server is powered down or removed from the enclosure. This feature
eliminates the power cycle requirement for a server to recover.
Serial Number (Logical) Settings
The serial number (logical) setting feature enables users to add a serial number (logical) and UUID
(logical) to server profiles. By configuring Virtual Connect to assign serial numbers (logical), 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
features prevents the user from having to reinstall serial number sensitive software after a system recovery.
If a user needs to access the physical serial number of a server blade, the OA displays both the physical
and serial numbers (logical).
After server profile creation, the following guidelines apply:
•
Serial numbers (logical) can be changed from factory default to VC-assigned.
•
Factory default serial numbers cannot be changed to serial numbers (logical).
•
User-defined serial number (logical) ranges can be expanded.
•
User-defined serial number (logical) ranges cannot be reduced.
•
All components must be at the required versions or the feature does not function:
o
OA, v2.20 or higher
o
iLO, v1.60 or higher

CAUTION:
The use of Serial Number (Logical) Settings might prevent the proper operation of
software designed to track servers by serial number or UUID. Do not enable this feature until
you consider and understand the impact to the entire software environment in which the
servers operate. This impact includes, but is not limited to, warranty service, asset tracking,
server deployment, and software licensing.
