Initiator Group Configuration<\/h4>\n
I already have an Initiator group I call esx. \u00a0This is all my ESX servers that share the LUNs. \u00a0When I first saw this interface I didn’t know what to do. \u00a0It turns out that some of the links you can right click on to get details.<\/p>\n
Here I say Add Initiator and will plug in my ESX initiator. \u00a0The problem is, I haven’t defined on on my ESX server yet. \u00a0So let’s do that then come back.<\/p>\n Clicking on the host inside the Configuration tab, we first click on Storage Adapters. \u00a0Under Add in the top right we can add a new Software iSCSI initiator.<\/p>\n Now, go back to the Storage Adapters menu and we’ll attach this interface to our software initiator.<\/p>\n Click on the iSCSI initiator and select properties on the detail screen on the bottom. \u00a0On the network configuration tab, select the iSCSI adapter.<\/p>\n In the dynamic discovery tab, we add the UCS Invicta:<\/p>\n Closing this window, it will rescan the devices and you’ll be disappointed to see that the Invicta LUN we created will not be shown. \u00a0This is because we didn’t add the iSCSI LUN to our initiator group.<\/p>\n At this point as a quick sanity check, I usually ssh into the box at this point and make sure I can ping the UCS Invicta appliance. \u00a0If that doesn’t work then you’re not going to get much farther.<\/p>\n Now we go back to the Invicta Appliance and add our LUN into the initiator group. \u00a0Right click on the initiator group you have (or create a new one) and then select ‘Add Initiator’<\/p>\n <\/p>\n The next screen you fill in the Initiator that you see on the vCenter screen under Storage Adapters. \u00a0Mine was iqn.1998-01.com.vmware:esx04-1e63ab9d<\/p>\n Right clicking on the Initiator group again will allow us to add the LUN to this group.<\/p>\n<\/a><\/p>\nESX iSCSI configuration<\/h2>\n
<\/a>Now that we have an iSCSI Adapter, we need to connect it to a physical interface. \u00a0Usually with iSCSI we have a separate vmkernel interface that we can use.<\/p>\n<\/a><\/p>\n<\/a><\/p>\n<\/a><\/a><\/a>\u00a0After you do this you typically create another one for iSCSI-B to give it network redundancy. \u00a0We’ll omit this here as we’re just showing the basic idea.<\/p>\n<\/a><\/p>\n<\/a><\/p>\nFinishing off the Connection<\/h2>\n
<\/a><\/p>\n<\/a>After adding you should see it in the list of initiators.<\/p>\n<\/a><\/p>\n
