Tips WWPN address notation is represented by 16 hex digits. The digits may be separated by colons. When
entering WWPN addresses, colons can be omitted or placed anywhere in the address notation as long as
they do not leave one character without a partner character. The entry should be zero-filled from the most
significant (the left-most) character position.
The following examples are correct:
• 0000:0000:1234:5678
• 0A0F2860:02111750
• 0A0F286002111750
The following examples are incorrect:
• 1:234:567:8:91:23:FF:6
• 12:34:56
The secondary WWPN and LUN combination is optional. The secondary combination is mapped to the
logical target name and LUN combination as an alternate, if the primary WWPN and LUN combination
is not available.
When you map a target using WWPN and the target needs to be accessed in a high availability cluster,
you must specify both the primary WWPN (the WWPN of the storage resource as known to the first
storage router in the cluster) and the secondary WWPN (the WWPN of the storage resource as known to
the second storage router in the cluster). The secondary WWPN value may need to be retrieved by
issuing the appropriate commands (such as the show devices command) from the second node in the
cluster, or by temporarily attaching the secondary port of the storage device to the first storage router.
When a target is added, it is by default enabled. However, it is not associated with any access list
(“accesslist none”), effectively disabling access to the target from any IP hosts. Use the
scsirouter target accesslist command to enable access to this storage target for selected IP hosts.
See Chapter 6, “Configuring SCSI Routing,” for more information about configuring SCSI routing
instances on the SN 5428-2 Storage Router.
Note When making changes to SCSI routing instances (such as adding or deleting targets or changing access)
be sure to make the complimentary changes to the iSCSI configuration of IP hosts using these services
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.
Use the force keyword to allow mapping of the same storage array control LUN in multiple targets. Do
not use the force keyword to LUN-map the same data LUN in multiple targets. LUN-mapping of the
same LUN in multiple targets is advised for a control LUN on a storage controller only.
