HP Virtual Connect 4Gb Fibre Channel Module for c-Class BladeSystem - Manual (Page 123)

Configuring the Virtual Connect domain using the CLI 123
• Assigning a VC-defined WWN
• Changing the Fibre Channel boot parameters
IMPORTANT: For Virtual Connect v2.1x, the server blade must be powered off for all profile
changes if a Flex-10 NIC is installed in the server, and the server is connected to an HP Virtual
Connect Flex-10 Module or to an empty bay.
If any of the listed settings are changing, the server must be powered off before the profile action can occur.
If the server blade is not powered off, a message appears and no changes are made. In this case, power off
the server blade and repeat the action.
When server side settings are changing, the following operations require that server blades be powered off:
• Assigning a profile to a server blade already installed in a device bay
• Deleting a profile, moving a profile to a different device bay, or unassigning a profile from the existing
bay
• 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
• When assigning a VC-Assigned serial number (logical)
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, and BIOS Fibre Channel boot settings are used
Flex-10 connection changes that require power off
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:
