35.3. 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 set up 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
Example 35.5. Set the iface IP address of a Chelsio card
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
