HP Virtual Connect for c-Class BladeSystem Version 3.70/3.75 User Guide

Virtual Connect server profiles 162
In the iSCSI HBA Connections section, add an iSCSI connection. Select a VC network, and then select a boot
setting:
• Disabled—Only iSCSI offload is available. Boot is unavailable.
• Primary—Enables you to set up a fault-tolerant boot path and displays the screen for Flex-10 iSCSI
connections (on page 162). If Primary is already configured, this setting changes to Secondary.
• USE-BIOS—Indicates if boot will be enabled or disabled using the server iSCSI BIOS utility.
The multiple network feature is not supported for iSCSI connections.
VCM looks at the number and types of connections in the profile—FCoE, iSCSI, and Ethernet. FCoE
connections are assigned first, followed by iSCSI and then by Ethernet. It is possible that some connections
will be unmapped. On server boot, the adapter enumerates functions configured by VCM. Any personality
change triggers a server reboot during POST.
After creating the iSCSI offload connections, use the iSCSI BIOS utility or OS tools to configure all iSCSI
parameters.
IMPORTANT:
After a profile has been created with iSCSI offload and assigned to a server, this
iSCSI offload configuration remains until it is manually removed through the system BIOS or OS
utility, even if the iSCSI offload is removed from the profile. Additionally, if iSCSI targets are
added using the system BIOS or the OS utility, those targets remain until they are manually
removed.
Flex-10 iSCSI connections
Use this screen to set the Flex-10 iSCSI connections.
iSCSI is only supported when using the following hardware:
• HP NC551i Dual-Port FlexFabric Converged Network Adapters
• HP NC551m Dual-Port FlexFabric Converged Network Adapters
• HP NC553i 10Gb 2-port FlexFabric Converged Network Adapter
• HP NC553m 10Gb 2-port FlexFabric Converged Network Adapter
• HP Virtual Connect FlexFabric 10Gb/24-port Module
• HP Virtual Connect Flex-10 10Gb Ethernet Module
• Any Ethernet switch
• Any target that supports the iSCSI protocol, for example, the HP LeftHand Networks 2120 with 10Gb
iSCSI (CX4 connection)
You might need to update the BIOS on the mezzanine card for iSCSI to work. For more information on the
BIOS as well as additional support hardware, see the QuickSpecs on the Installing tab of the HP BladeSystem
Technical Resources website (http://www.hp.com/go/bladesystem/documentation).
