Chapter 6 Configuring SCSI Routing
Creating and Configuring an Access List
Target-only mapping using WWPN addressing
Use the following procedure to map iSCSI targets to storage devices by physical storage address.
Use the following procedure to map iSCSI targets to storage devices by index numbers.
Creating and Configuring an Access List
Creating an access list consists of naming the new list. Configuring an access list consists of identifying
the IP hosts that have permission to access storage devices via iSCSI target names.
IP hosts can be identified by:
• IP address
• CHAP user name (used for iSCSI authentication)
• iSCSI Name of the IP host - The iSCSI Name is a UTF-8 character string based on iSCSI functional
requirements. It is a location-independent permanent identifier for an iSCSI node. An iSCSI node
can be an initiator, a target, or both.
An access list can contain one or more types of identification entries. If an identification entry type exists
in the access list, an IP host attempting to access the associated storage target must have a matching entry
defined in the access list. For example, if an access list contains both IP address and iSCSI Name
identification entry types, then every IP host that requires access to the associated set of storage
resources must have a matching IP address and iSCSI Name entry in the access list.
An access list is necessary if you want to specify access to iSCSI targets on a per-IP host basis. An access
list is not necessary if you want to specify that any IP host can have access to the iSCSI targets
configured in a SCSI routing instance; however, in this case you must still configure access as described
in Configuring Access to iSCSI Targets, page 6-11.
Note For each SN 5428-2 Storage Router, you can create a maximum of 100 access lists and configure up to
200 identification entries across all access lists.
Command Description
Step 1
enable Enter Administrator mode.
Step 2
scsirouter zeus target
pegasus_email wwpn
22000020371912da
Specify desired SCSI routing instance (zeus). Specify iSCSI target
(pegasus_email), and map it to the desired physical address
(WWPN 22000020371912da) and any LUNs available as part of
that WWPN.
Command Description
Step 1
enable Enter Administrator mode.
Step 2
scsirouter zeus target
pegasus_email wwpn #?
Specify desired SCSI routing instance (zeus). Specify iSCSI target
(pegasus_email), and prompt for an indexed list of available
storage addresses using the number sign and a question mark (#?).
Step 3
scsirouter zeus target
pegasus_email wwpn #4
Choose a physical address designated by an index number (see
index number 4 in Example 6-2) to map the iSCSI target
(pegasus_email) to desired physical address (WWPN
22000020371912da).
