21.11.3. Configuring an iface for iSCSI Offload
By default, 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 (target_IP
[]) 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 iface
, use:
iscsiadm -m iface -I iface_name
-o update -n iface.ipaddress -v target_IP
For example, to set the iface
IP address of a Chelsio card (with iface
name cxgb3i.00:07:43:05:97:07
) to 20.15.0.66
, use:
iscsiadm -m iface -I cxgb3i.00:07:43:05:97:07 -o update -n iface.ipaddress -v 20.15.0.66
