Configuring iSCSI
Dynamic Importing
To enable dynamic importing of Fibre Channel targets into iSCSI, use the iscsi import target fc
command.
The IPS module maps each physical Fibre Channel target port as one iSCSI target. That is, all LU
accessible via 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 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.
If you have configured a switch name, then the switch name will be used instead of the management IP
address. If you have not configured a switch name, the management IP address will be 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>
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.
Configuring Dynamic Importing with Device Manager
To dynamically import Fibre Channel targets as iSCSI targets, follow these steps:
Step 1 Choose IP > iSCSI from 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.
Static Importing
You can manually (statically) create an iSCSI target and assign a node name to it. A statically-mapped
iSCSI target can either contain the whole FC target port, or it can contain one or more LUs from a Fibre
Channel target port.
To create a static iSCSI virtual target for the Fibre Channel target port, follow these steps
