Configuring an iface for Software iSCSI
135
Using the previous example, the iface settings of the same Chelsio video card (i.e. iscsiadm -m
iface -I cxgb3i.00:07:43:05:97:07) would appear as:
# BEGIN RECORD 2.0-871
iface.iscsi_ifacename = cxgb3i.00:07:43:05:97:07
iface.net_ifacename = <empty>
iface.ipaddress = <empty>
iface.hwaddress = 00:07:43:05:97:07
iface.transport_name = cxgb3i
iface.initiatorname = <empty>
# END RECORD
21.11.2. Configuring an iface for Software iSCSI
As mentioned earlier, an iface configuration is required for each network object that will be used to
bind a session.
Before
To create an iface configuration for software iSCSI, run the following command:
iscsiadm -m iface -I iface_name --op=new
This will create a new empty iface configuration with a specified iface_name. If an existing iface
configuration already has the same iface_name, then it will be overwritten with a new, empty one.
To configure a specific setting of an iface configuration, use the following command:
iscsiadm -m iface -I iface_name --op=update -n iface.setting -v hw_address
For example, to set the MAC address (hardware_address) of iface0 to 00:0F:1F:92:6B:BF,
run:
iscsiadm -m iface -I iface0 - -op=update -n iface.hwaddress -v
00:0F:1F:92:6B:BF
Warning
Do not use default or iser as iface names. Both strings are special values used by
iscsiadm for backward compatibility. Any manually-created iface configurations named
default or iser will disable backwards compatibility.
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
3
) 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:
