21.11.3. Configuring an iface for iSCSI Offload
iscsiadm will create an
iface configuration for each Chelsio, Broadcom, and ServerEngines port. To view available
iface configurations, use the same command for doing so in software iSCSI, i.e.
iscsiadm -m iface.
Before using the
iface of a network card for iSCSI offload, first set the IP address (
) that the device should use. For ServerEngines devices that use the
be2iscsi driver (i.e. ServerEngines iSCSI HBAs), the IP address is configured in the ServerEngines BIOS setup screen.
For Chelsio and Broadcom devices, the procedure for configuring the IP address is the same as for any other
iface setting. So to configure the IP address of the
iscsiadm -m iface -I
iface_name -o update -n iface.ipaddress -v
For example, to set the
iface IP address of a Chelsio card (with
iscsiadm -m iface -I cxgb3i.00:07:43:05:97:07 -o update -n iface.ipaddress -v 126.96.36.199
