Subject: Re: [PATCH 2/2] scsi: storvsc: Add support for FC lightweight host.

Hi,

There is no way to issue a lip directly as  the current client for this 
feature ( storvsc ) does not handle that request as a physical fc hba 
can. Storvsc only has two fc attributes exposed -  port_name and node_name.

You can rescan the bus with the standard echo "- - -" > 
/sys/class/scsi_host/hostX/scan.
