Dell PowerVault MD32x xi Configuration Gu ide for VMware ESX 4.1 Server Sof tware Page 14 There are some suggested co nfigurations depending on the number of NICs that will be used for iSCSI traffic. Every environment w ill differ dependin g on the number of ho sts, the number of members, and the number of volumes.
Dell PowerVault MD32x xi Configuration Gu ide for VMware ESX 4.1 Server Sof tware Page 15 To verify the configuration en ter the following command : esxcfg-vswitch – l The output will look si milar .

Dell PowerVault MD32x xi Configuration Gu ide for VMware ESX 4.1 Server Sof tware Page 19 By default, all the vmnics are assigned to each VMkern el port. We need to remove all bu t one vmnic from each VMkernel port so that each VMkernel port has only one uplink.

Dell PowerVault MD32x xi Configuration Gu ide for VMware ESX 4.1 Server Sof tware Page 21 Step5: Enable V Mware iSCSI Software Initiator The next step, if it has n ot been done already, is to enab le the iSCSI initiator to prepare th e ESX host to connect to the P owerVault SAN.
Dell PowerVault MD32x xi Configuration Gu ide for VMware ESX 4.1 Server Sof tware Page 22 This will enable the soft ware iSCSI initiator. To verify th at it is enabled type the following command: esxcfg-swiscsi – q This can also be accompli shed by using the vCent er GUI.
Dell PowerVault MD32x xi Configuration Gu ide for VMware ESX 4.1 Server Sof tware Page 23 Step6: Binding V Mkernel Ports to iSC SI Software Initiato r This next step will bind the VMkernel ports, whi ch were configured in Step 4 earlier, to the iSCSI Softwar e Initiator.
Dell PowerVault MD32x xi Configuration Gu ide for VMware ESX 4.1 Server Sof tware Page 24 In this example we se e that iSCSI1 is vmk0, iSCSI2 is vmk1, and iSCSI3 is vmk2.

Dell PowerVault MD32x xi Configuration Gu ide for VMware ESX 4.1 Server Sof tware Page 28 2. Under iSCSI Access yo u can choose to use an IP Address or I nitiator Name. 3. To find the iSCSI Initia tor Name from the vCenter GUI go to Configurat ion -> Storage Adapt ers .
Dell PowerVault MD32x xi Configuration Gu ide for VMware ESX 4.1 Server Sof tware Page 29 4. Check Disallow un -named discovery ses sions , if desired. Step8: Connect to a Volume on PowerVa ult SAN The next step is to connect to the volume on th e SAN and verify the connection status .
Dell PowerVault MD32x xi Configuration Gu ide for VMware ESX 4.1 Server Sof tware Page 30 Step9: Enabling VM ware Native Multipathing – MRU One of the new ad vanced features that is enabled by con figuring the iSCSI Software Initia tor the way we have is that now we can t ake advantage of MPIO by using MRU.

Dell PowerVault MD32x xi Configuration Gu ide for VMware ESX 4.1 Server Sof tware Page 33 Step A3: Assign Net work Adapters Just like in the previous example, the next step in the proce ss is to assign the network ad apters (NICs) that will be attached to the iSC SI network and used for iS CSI traffic.
Dell PowerVault MD32x xi Configuration Gu ide for VMware ESX 4.1 Server Sof tware Page 34 Click the Network Adapte rs tab. Then click Add . This will op en up the Add Adap ter Wizard. From here select the vmnics that you want to add to the vSwitch. In our example it will be vmnic2 a nd vmnic3.

Dell PowerVault MD32x xi Configuration Gu ide for VMware ESX 4.1 Server Sof tware Page 36 The important thing to note is that und er the Uplinks section there is only one vmnic a ssigned to each iSCSI VMkernel port and that they are evenly distribu ted across them all.
Dell PowerVault MD32x xi Configuration Gu ide for VMware ESX 4.1 Server Sof tware Page 37 The first thing to do is to note the vmhba# of the iSCSI So ftware Initiator.
Dell PowerVault MD32x xi Configuration Gu ide for VMware ESX 4.1 Server Sof tware Page 38 In this example we se e that iSCSI1 is vmk0, iSCSI 2 is vmk1, iSCSI3 is vmk2 and iSCSI4 is vmk3.

Now that we know the vmhba# and the vmk# we can map each VMkernel Port to t he iSCSI Software Initiator.
