Server profile troubleshooting
In some cases, server profiles can be assigned to server blades when certain mismatches exist between
the server profile definition and the server blade. The following list summarizes Virtual Connect behavior
under these circumstances:
• If the number of Network connections in the profile is more than the number of physical Ethernet
ports, the profile is assigned, but a warning message appears.
• If a switch other than a Virtual Connect Ethernet switch is connected to any port in the profile, the
profile is assigned, but the MAC address is not changed on the NIC. A warning message appears.
• If the number of Fibre Channel connections in the profile is more than the number of physical Fibre
Channel HBA ports, the profile is assigned, but a warning message appears.
IMPORTANT: When used with Virtual Connect, the HP Integrity BL860c Server Blade does
not support configuration of Fibre Channel boot parameters or PXE settings. Other Virtual
Connect server profile settings are configured properly when the appropriate BL860c
firmware is used.
The Virtual Connect Manager may reset when creating and assigning many server profiles using VCEM.
This behavior has been seen when creating more than 100 server profiles all at once.
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. The Virtual Connect Manager also
provides an opportunity to power off the server blade before such operations.
If any changes are made 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
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
