[Xen-API] SG_IO for iscsi targets in XCP

[George Shuklin <george.shuklin@xxxxxxxxx>]

Good day.

I'm researching if XCP by anyway is issuing some SCSI commands like
reservation or persistent reservation. I done 'greping' via source code
for SG_IO ioctl() and found just few innocent inquiry/id requests.

Just to be sure: Is any SCSI-specific features used in XCP for cluster
management or resource locking? Or iscsi used only as generic block
device with LVM?

Thanks.
