Hey!
If you have downloaded the latest version of VSC (4.2.1) you want to use an AD account.
1. You can install VSC non-disruptively and you want to do this on the vCenter server
2. Go to https://localhost:8143/Register.html
3. Type the host name or IP address of the vCenter Server and the administrative credentials for the
vCenter Server and register.
Then...
Steps
1. Open the vSphere Client and log into your vCenter Server.
2. Select a Datacenter in the Inventory panel, and then select the NetApp tab.
3. If the discovery process does not start automatically, or if you want to discover new resources and
update information, click Update on the Overview panel of Monitoring and Host Configuration.
4. Right-click any discovered storage controllers with the status Authentication Failure and select
Modify Credentials.
5. Fill in the information in the Modify Credentials dialog box.
After you finish
After discovery is complete, use Monitoring and Host Configuration to configure ESX or ESXi host
settings for any hosts displaying an Alert icon in the Adapter Settings, MPIO Settings, or NFS
Settings columns.
SET YOUR TIME OUTS ON EVERY ESXi BOX!!!! (This requires downtime)
This is just to get you started, I took all of this from the document listed below.
