In the documentation is a note about setting the vSphere Management IP address within vSphere.   That's not set when you install vSphere.  The logs are stored on a share on the Appliance.  If you browse to the appliance IP address you should see the share and the logs.  That's also where the diags are saved when you run the appliance diags.  Regards, 
I just had my SAN installed 2 weeks ago by an outside company...so I am very new to all of this.  My terminology might not be great or accurate.  I have been trying hard to install some software to help me with snapshots or just in general to help make life easier.  The company suggested VSM 3.5 and I tried to install it yesterday.  I think the last step is failing, but I can't find where the error log is.  I get following message when I try to do option #3 from the VSM console to Configure VMware vSphere Storage APIs for Storage Awareness (VASA): VMWare VCenter registration with VASA Provider failed (see setup.sh-1359553205.log There are a whole lot of things I still don't know so maybe I shouldn't be installing this at all.  I believe we have a PS6100 and all the latest patches and updates.  I've gotten overviews of connecting to the SAN and the vSphere client and we have 8 servers up and running.  But, I still don't have much in the way of snapshots and a snapshot backup strategy going yet.  Any thoughts or suggestions will be great. I would like to figure out how to find the error log and read the message though if nothing else.   Thanks, Ryan (very new)
Install VSM 3.5
