vSphere Storage VMkernel Adapter (vmk#) Physical Network Adapter (vmnic#) vmk1 Active Adapters vmnic1 Unused Adapters vmnic2 vmk2 Active Adapters vmnic2 What to do next Unused Adapters vmnic1 After you perform this task, bind the virtual VMkernel adapters to the software iSCSI or dependent hardware iSCSI adapters. Bind iSCSI and VMkernel Adapters in the vSphere Web Client Bind an iSCSI adapter with a VMkernel adapter. Prerequisites Create a virtual VMkernel adapter for each physical network adapter on your host. If you use multiple VMkernel adapters, set up the correct network policy. Required privilege: Host.Configuration.Storage Partition Configuration Procedure 1 Browse to the host in the vSphere Web Client navigator. 2 Click the Manage tab, and click Storage. 3 Click Storage Adapters and select the software or dependent iSCSI adapter to configure from the list. 4 Under Adapter Details, click the Network Port Binding tab and click Add. 5 Select a VMkernel adapter to bind with the iSCSI adapter. NOTE Make sure that the network policy for the VMkernel adapter is compliant with the binding requirements. You can bind the software iSCSI adapter to one or more VMkernel adapters. For a dependent hardware iSCSI adapter, only one VMkernel adapter associated with the correct physical NIC is available. 6 Click OK. The network connection appears on the list of VMkernel port bindings for the iSCSI adapter. Review Port Binding Details in the vSphere Web Client Review networking details of the VMkernel adapter that is bound to the iSCSI adapter. Procedure 1 Browse to the host in the vSphere Web Client navigator. 2 Click the Manage tab, and click Storage. 3 Click Storage Adapters and select the software or dependent iSCSI adapter from the list. 4 Under Adapter Details, click the Network Port Binding tab and click View Details. 5 Review the VMkernel adapter information by switching between available tabs. 96 VMware, Inc.
Managing iSCSI Network Special consideration apply to network adapters, both physical and VMkernel, that are associated with an iSCSI adapter. After you create network connections for iSCSI, an iSCSI indicator on a number of Networking dialog boxes becomes enabled. This indicator shows that a particular virtual or physical network adapter is iSCSI-bound. To avoid disruptions in iSCSI traffic, follow these guidelines and considerations when managing iSCSI-bound virtual and physical network adapters: n Make sure that the VMkernel network adapters are assigned addresses on the same subnet as the iSCSI storage portal they connect to. n iSCSI adapters using VMkernel adapters are not able to connect to iSCSI ports on different subnets, even if those ports are discovered by the iSCSI adapters. n When using separate vSphere switches to connect physical network adapters and VMkernel adapters, make sure that the vSphere switches connect to different IP subnets. n If VMkernel adapters are on the same subnet, they must connect to a single vSwitch. n If you migrate VMkernel adapters to a different vSphere switch, move associated physical adapters. n Do not make configuration changes to iSCSI-bound VMkernel adapters or physical network adapters. n Do not make changes that might break association of VMkernel adapters and physical network adapters. You can break the association if you remove one of the adapters or the vSphere switch that connects them, or change the 1:1 network policy for their connection. iSCSI Network Troubleshooting A warning sign indicates non-compliant port group policy for an iSCSI-bound VMkernel adapter. Problem The VMkernel adapter's port group policy is considered non-compliant in the following cases: n The VMkernel adapter is not connected to an active physical network adapter. n The VMkernel adapter is connected to more than one physical network adapter. n The VMkernel adapter is connected to one or more standby physical adapters. n The active physical adapter is changed. Solution Follow the steps in “Change Port Group Policy for iSCSI VMkernel Adapters,” on page 92 to set up the correct network policy for the iSCSI-bound VMkernel adapter. Using Jumbo Frames with iSCSI ESXi supports the use of Jumbo Frames with iSCSI. Jumbo Frames are Ethernet frames with the size that exceeds 1500 Bytes. The maximum transmission unit (MTU) parameter is typically used to measure the size of Jumbo Frames. ESXi allows Jumbo Frames with the MTU up to 9000 Bytes. When you use Jumbo Frames for iSCSI traffic, the following considerations apply: Chapter 11 Configuring iSCSI Adapters and Storage n The network must support Jumbo Frames end-to-end for Jumbo Frames to be effective. n Check with your vendors to ensure your physical NICs and iSCSI HBAs support Jumbo Frames.
