Hello.

I need SCSI-3 PR in guest (veritas cluster fencing).
The VBox does not support SCSI-3 PR natively but it also inhibits the support on iSCSI remote disks (VBoxManage storageattach --medium iscsi ...).
I have following situations:
(1) - this works well (vxfentsthdw (test SCSI-3 PR) finished without error) :

iSCSI target (COMSTAR on Sol11) -> net -> iSCSI initiator (Sol10) in guest

(2) - this does not work (vxfentsthdw fails on the first test) :

iSCSI target (COMSTAR on Sol11) -> net -> iSCSI initiator (Sol11) virtualbox -> emulation (LSI SCSI/LSI SAS) -> scsi disk (Sol10) in guest

Why VBox touches "SCSI" commands on "passthrough" outside iSCSI disk <-> inside SCSI disk ?
Is there someone with working configuration similar to (2) ?

Thanks, Martin Cerveny
