I have added 2 additional LSI Logic SAS controllers (ESX 4.1) to a win 2k8 r2 VM – I want to attach database luns to one controller and log luns to another with snapdrive 6.3 with ESX sw iscsi RDM luns.
I cannot work out how to attach to luns to the added controllers??
SDW 6.3 has a new feature of creating RDM vmdk disks, I guess this is what you are interested in. If so, you need to map LUN to esx and create a vmfs datastore first. Now while creating a lun from SDW, it asks whether you want to create a RDM disk if opted for that it will take you to a screen where all the vmfs datastores present in the ESX are displayed. Select the datastore you want and proceed, Now a vmdk will be created in the datastore and will be attached as a disk in your VM. Hope this is useful.
As for choosing iscsi controller, you can manage it through SDW, whenever you create or connect a LUN, it asks which initiator to use.
