Re: [Xen-API]Introducing VDI in ISCSISR fail

[Julian Chesterfield <julian.chesterfield@xxxxxxxxxxxxx>]

That's correct. SR scan always executes on the SR master only, so for 
shared SRs the SR master is the pool master. Are you trying to introduce 
a LUN to all nodes in the same pool, or is this just mapped to a single 
host? If the latter, then the SR should not be shared.
