HP Virtual Connect Flex-10 10Gb Ethernet Module for c-Class BladeSystem - Manual (Page 275)

Maintenance and troubleshooting 275
• Making modifications to a profile that affect settings on the server blade; for example, PXE
enable/disable, changing the number of connections, or changing Fibre Channel boot parameters
• Assigning a VC-assigned serial number
The following operations do not require the server blade to be powered off:
• Changing the network connected to an already defined Ethernet port
• Changing the Fabric connected to a Fibre Channel port
• 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

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

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
