Chapter 6 Configuring SCSI Routing

Configuration Tasks

To configure SCSI routing on your SN 5428-2 Storage Router, perform the following steps:

Step 1 Create a SCSI routing instance. Once an instance is created, you will configure that instance with

parameters for a server interface, iSCSI targets, and access by IP hosts.

Step 2 Configure a server interface with or without VLAN.

Step 3 Configure iSCSI targets.

Step 4 (Optional) Create and configure a named access list. A named access list contains IP host identification

information and is necessary if you want to control access to iSCSI targets on a per-IP host basis.

Step 5 Configure access to iSCSI targets. Associate named access lists to iSCSI targets to control target access

on a per-IP host basis, or allow any IP host access to iSCSI targets.

Step 6 Verify and save configuration.

Note Although this is shown as the last step, you can verify and save the configuration at any point in

the process of performing the configuration tasks. Save your configuration by using the

save all bootconfig CLI command. This command saves all configuration data to the bootable

configuration, which is then used when the storage router is rebooted.

Caution When making changes to a SCSI routing instance (such as adding or deleting targets or changing access)

be sure to make the complementary changes to the iSCSI driver configuration of IP hosts that use that

SCSI routing instance to access the storage resources. See the readme files for the appropriate iSCSI

drivers for additional details. (You can access the latest iSCSI drivers and readme and example

configuration files from Cisco.com.)

Figure 6-1 illustrates SCSI routing configuration elements, and Figure 6-2 illustrates the example

configuration used in this chapter. Figure 6-3 illustrates how the configuration of SCSI routing instances

determines VLAN access to storage devices.

Note Configuring the SCSI routing instance does not include configuring the Fibre Channel (FC) interfaces.

Once the SCSI routing instance is configured, all the FC interfaces are available. See Chapter 5,

“Configuring Fibre Channel Interfaces,” for more information on the FC interfaces and default

characteristics.
