Chapter 20 iSCSI Configuration

Configuring iSCSI

Note The IPS module does not import Fibre Channel targets to iSCSI by default. Either dynamic or static

mapping must be configured before the IPS module makes Fibre Channel targets available to iSCSI

initiators. When both are configured, statically mapped Fibre Channel targets have a configured name.

Targets that are not statically imported are advertised with the name created by the conventions explained

in this section.

Dynamically Importing Fibre Channel Targets

The IPS module maps each physical Fibre Channel target port as one iSCSI target. That is, all LUs

accessible through the physical storage target port are available as iSCSI LUs with the same LU number

(LUN) as in the storage target.

For example, if an iSCSI target was created for a Fibre Channel target port with pWWN

31:00:11:22:33:44:55:66 and that pWWN contains LUN 0 through 2, those LUNs would become

available to an IP host as LUNs 0 through 2 as well.

Note If you have configured a switch name, then the switch name is used instead of the management IP

address. If you have not configured a switch name, the management IP address is used.

The iSCSI target node name is created automatically using the iSCSI qualified name (IQN) format. The

iSCSI qualified name is restricted to a maximum name length of 223 alphanumeric characters and a

minimum length of 16 characters.

The IPS module creates an IQN formatted iSCSI node name using the following conventions:

•IPS ports that are not part of a VRRP group use this format:

iqn.1987-05.com.cisco:05.<mgmt-ip-address>.<slot#>-<port#>-<sub-intf#>.<Target-pWWN>

•IPS ports that are part of a VRRP group use this format:

iqn.1987-05.com.cisco:05.vrrp-<vrrp-ID#>-<vrrp-IP-addr>.<Target-pWWN>

•Ports that are part of a PortChannel use this format:

iqn.1987-02.com.cisco:05.<mgmt-ip-address>.pc-<port-ch-sub-intf#>.<Target-pWWN>

Note With this format, each IPS port in a Cisco MDS 9000 Family switch creates a different iSCSI target node

name for the same Fibre Channel target.

To dynamically import Fibre Channel targets as iSCSI targets, follow these steps:

Step 1 Choose IP > iSCSI in Device Manager. You see the iSCSI dialog box.

Step 2 Choose the Targets tab to display a list of existing iSCSI targets.

Step 3 Check the Dynamically Import FC Targets check box.

Step 4 Click Apply to save this change or click Cancel to close the dialog box without saving any changes.
