• Changing the speed of a Fibre Channel port
• Assigning or unassigning server profiles, if server factory defaults are used for MAC addresses and
WWNs, BIOS Fibre Channel boot settings are used, and PXE is not being enabled or disabled (USE
BIOS for all network connections)
Exceptions for Flex-10 connection changes are specified in the following sections.
Flex-10 connection changes that require power off
Always power off server blades with Flex-10 connections in the following instances:
• Adding a connection that is mapped to Flex-10
• Removing a connection that is mapped to Flex-10
• Assigning a profile to a server that maps Flex-10 connections
• Unassigning a profile with Flex-10 connections
Flex-10 connection changes that do not require power off
With Virtual Connect Manager v2.10 and higher, it is not necessary to power off a server blade with Flex-10
connections in the following instances:
• Changing a connection's network:
o From a single network to another single network
o From a single network to multiple networks
o From multiple networks to a single network
• Modifying the networks or VLAN IDs in a connection with multiple networks
With Virtual Connect Manager v2.30 and higher, it is not necessary to power off a server blade with Flex-10
connections in the following instances:
• Changing a connection's network:
o From "unassigned" to a single network
o From a single network to "unassigned"
o From "unassigned" to multiple networks
o From multiple networks to "unassigned"
• Changing the requested bandwidth
FCoE connection changes that require power off
• Adding an FCoE connection to an assigned server profile
• Removing an FCoE connection from an assigned server profile
• Assigning a profile containing FCoE connections to a server
• Changing FCoE boot parameters
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.
