Points to note when installing IIS:
Verify that IIS is installed and configured identically on all nodes hosting the service group. Verify that the sites to be monitored are on the shared storage (VMDg) or non-shared storage (VMNSDg).
Import the disk groups and mount the volumes that contain the website data, on the first node.
For a new IIS installation, while creating new web sites, create the site folder on the shared storage (VMDg) or non-shared storage (VMNSDg) and place the site content in that folder.
Change the default home directory path for all the IIS sites to be monitored to a location on the shared storage (VMDg) or non-shared storage (VMNSDg). See the IIS documentation for instructions.
For existing web sites, stop the sites and then move the website content to volumes on the shared storage (VMDg) or non-shared storage (VMNSDg). You must also reconfigure the home directory location for the website in IIS and then restart the website again.
Verify the port numbers assigned to IIS sites are not used by other applications or sites.
Synchronize the IIS configuration on all nodes hosting the service group.
