Configuring the Virtual Connect domain using the CLI 178

Restart after OA credential recovery
The 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 "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.

General requirements for adding FC or FCoE connections

Adding FC and FCoE connections is generally allowed during profile add and edit operations. It is not

allowed in some specific cases. Observe the following general requirements:

When a profile is added, the FC/FCoE connections initially displayed are based on the FC/FCoE
module configuration in the domain. A pair of horizontally adjacent FC/FCoE-capable modules has

two connections.

Connections can only be added or removed from the bottom. You can only add or delete connections
at the end of the list.

You can remove connections at any time (one at a time, from the bottom).

If the existing profile connections do not match the current FC/FCoE module configurations, the add
operation is not allowed.

The current maximum number of per server profile FC/FCoE connections mapped to the same I/O bay
is four, unless you are using the HP Integrity BL890c i4 Server Blade.

o

When FlexFabric modules exist in I/O bays 1 and 2, there can be an additional eight FCoE
connections that will get mapped to LOMs 3 and 4 on the blades in an Integrity BL890c i4 server.

The BL890c i4 server has CNA LOMs, which enable two FCoE connections to I/O bay 1 (from

LOMs 1 and 3) and two FCoE connections to I/O bay 2 (from LOMs 2 and 4).

The following table lists several scenarios that describe how adding FC/FCoE connections affects an existing

profile. The scenarios are true for FC module configurations and FC modules, as well as FCoE module

configurations and FCoE-capable modules.
