Target Storage Device Requiring LUN Mapping Example

This example scenario 2 assumes the following configuration:

7. Configure for static pWWN and nWWN for host 1.
1. In Device Manager, choose IP > iSCSI.
2. Click the Initiators tab.
3. Check the Node Address Persistent and Node Address System-assigned check boxes the Host 1 iSCSI initiator.
4. Click Apply.
8. Configure for static pWWN for Host 2.

2. Click the Initiators tab.
3. Right-click on the Host 2 iSCSI initiator and click Edit pWWN.
4. Select 1 from the System-assigned Num field and click Apply.
9. View the configured WWNs.

Note     The WWNs are assigned by the system. The initiators are members of different VSANs.

1. In Cisco DCNM-SAN, choose End Devices > iSCSI in the Physical Attributes pane.
2. Click the Initiators tab.
10. Create a zone for Host 1 and the iSCSI target in VSAN 1.

Note     Use the IP address of the host in zone membership configuration because the iSCSI interface is configured to identify all hosts based on IP address.

1. In Cisco DCNM-SAN, choose Zones > Edit Local Full Zone Database.
2. Select VSAN 1 from the VSAN drop-down menu in the Edit Local Full Zone Database dialog box.
3. Select the Zones folder in the left navigation pane and click Insert.
4. Set the Zone Name field to iscsi-zone-1 and click OK.
5. Select the iscsi-zone-1 folder in the left navigation pane and click Insert.
6. Set the ZoneBy radio button to WWN.
7. Set the Port WWN to the pWWN for the Fibre Channel target (that is, 21:00:00:20:37:6f:fd:97). and click Add.
8. Set the ZoneBy radio button to iSCSI IP Address/Subnet.
9. Set the IP Address/Mask field to the IP Address for Host 1 iSCSI initiator (10.11.1.10) and click Add.

Note     Fibre Channel storage for zone membership for the iSCSI initiator, either the iSCSI symbolic node name or the pWWN, can be used. In this case, the pWWN is persistent.

11. Create a zone set in VSAN 1 and activate it.
1. In Cisco DCNM-SAN, choose Zones > Edit Local Full Zone Database.
2. Select VSAN 1 from the VSAN drop-down menu in the Edit Local Full Zone Database dialog box.

7. Click Activate to activate the new zone set.
8. Click Continue Activation to finish the activation.
12. Create a zone with host 2 and two Fibre Channel targets.

Note     If the host is in VSAN 2, the Fibre Channel targets and zone must also be in VSAN 2.

Note     iSCSI interface is configured to identify all hosts based on node name.

1. In Cisco DCNM-SAN, choose Zones > Edit Local Full Zone Database.
2. Select VSAN 2 from the VSAN drop-down menu in the Edit Local Full Zone Database dialog box.

9. Set the ZoneBy radio button to iSCSI IP Address/Subnet.
10. Set the IP Address/Mask field to the IP Address for Host 2 iSCSI initiator (10.15.1.11) and click Add.
13. Create a zone set in VSAN 2 and activate it.
1. In Cisco DCNM-SAN, choose Zones > Edit Local Full Zone Database.
2. Select VSAN 2 from the VSAN drop-down menu in the Edit Local Full Zone Database dialog box.
3. Select the Zoneset folder in the left navigation pane and click Insert.
4. Set the Zoneset Name to zonset-iscsi-2 and click OK.
5. Click on the zoneset-iscsi-2 folder and click Insert.
6. Set the Zone Name field to iscsi-zone-2 and click OK.
7. Click Activate to activate the new zone set.
