Server management 126
With Virtual Connect Manager v2.1x, always power off server blades, 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*
• 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
* Virtual Connect Manager v2.30 and higher does not require power off for these actions.
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 the 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 the 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
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.
