A.7 Operation
A.7.1 Prerequisites
• Make sure that your client is connected to the server(s)
• The FlexBoot image is already programmed on the adapter card – see Section A.2
• For InfiniBand ports only: Start the Subnet Manager as described in Section A.4
• The DHCP server should be configured and started (see Section 4.3.3.1, “IPoIB Config-
uration Based on DHCP”, on page 50
• Configure and start at least one of the services iSCSI Target (see Section A.10) and/or
TFTP (see Section A.5)
A.7.2 Starting Boot
Boot the client machine and enter BIOS setup to configure “MLNX FlexBoot” to be the first on
the boot device priority list – see Section A.6.
If MLNX FlexBoot/iPXE was selected through BIOS setup, the client will boot from FlexBoot.
The client will display FlexBoot attributes, sense the port protocol – Ethernet or InfiniBand. In
case of an InfiniBand port, the client will also wait for port configuration by the Subnet Manager.
On dual-port network adapters, the client first attempts to boot from Port 1. If this fails,
it switches to boot from Port 2. Note also that the driver waits up to 90 seconds for
each port to come up.
In case sensing the port protocol fails, the port will be configured as an InfiniBand
port.
