Configuring iSCSI
Step 4 Click the Apply Changes icon to save these changes.
Note When an initiator is configured in any other VSAN (other than VSAN 1), for example VSAN 2, the
initiator is automatically removed from VSAN 1. If you also want it to be present in VSAN 1, you must
explicitly configure the initiator in VSAN 1.
VSAN Membership for iSCSI Interfaces
VSAN membership can be configured for an iSCSI interface, called the port VSAN. All the iSCSI
devices that connect to this interface automatically become members of this VSAN, if it is not explicitly
configured in a VSAN. In other words, the port VSAN of an iSCSI interface is the default VSAN for all
dynamic iSCSI initiators. The default port VSAN of an iSCSI interface is VSAN 1.
Caution Changing the VSAN membership of an iSCSI interface that is part of an iSLB VRRP group impacts load
balancing on the interface. See the
“Changing iSCSI Interface Parameters and the Impact on Load
Balancing” section on page 50-45.
To change the default port VSAN for an iSCSI interface using Device Manager, follow these steps:
Step 1 Choose Interface > Ethernet and iSCSI.
You see the Ethernet Interfaces and iSCSI dialog box (see Figure 50-21).
Step 2 Click the iSCSI tab.
You see the iSCSI interface configuration table (see Figure 50-22).
Step 3 Double-click the PortVSAN column and modify the default port VSAN.
Step 4 Click Apply to save these changes.
Example of VSAN Membership for iSCSI Devices
Figure 50-23 provides an example of VSAN membership for iSCSI devices:
• iSCSI interface 1/1 is a member of VSAN Y.
• iSCSI initiator host A has explicit VSAN membership to VSAN X.
• Three iSCSI initiators (host A, host B, and host C) C connect to iSCSI interface 1/1.
