The following examples are incorrect:
• 1:234:567:8:91:23:FF:6
• 12:34:56
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.
Examples The following example maps a logical target for SCSI router instance lab4. The logical target
webserver1 is mapped to the primary WWPN, 22:00:00:20:37:19:15:05.
[SN5428-2A]# scsirouter lab4 target webserver1 wwpn 22:00:00:20:37:19:15:05
The following example maps a logical target to a primary and secondary WWPN. You may need to obtain
the secondary WWPN from the storage router to which the secondary port of the device is attached, or
temporarily attach the storage device’s secondary port to the storage router being configured.
[SN5428-2A]# scsirouter lab5 target webserver9 wwpn 2200002037c6756d wwpn 2100002037c6747f
