Server blade power on and power off guidelines

Certain server profile changes require the server blade in the device bay to be powered off before the

change can be made. HP recommends that administrators power off servers with the server console before

attempting such operations within the Virtual Connect Manager.

If any changes are made to a server profile that require modifications to the server, the server blade must be

powered off. Network or fabric changes do not require the server blade to be powered off. Server-side

settings include the following:

• Assigning a VC- or user-defined MAC address

• Changing the PXE setting

• Assigning a VC-defined WWN

• Changing the Fibre Channel boot parameters

• Changing iSCSI boot parameters

• Adding or deleting a connection of any kind

• Changing the FlexNIC enumeration setting on a profile

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

• 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
