TGTD claim SPC-3 support. Change the inquiry data to report TrmTsk=0. This flag dissapeared in SPC-2 and is flagged "obsolete" in any later SPC standard. So this flag should be set to 0 in SPC-2 and later, including SPC-3. Change HiSup flag to 1. SAM4 describes this bit as : 4.6.3 LUNs overview All LUN formats described in this standard are hierarchical in structure even when only a single level in that hierarchy is used. The HISUP bit shall be set to one in the standard INQUIRY data (see SPC-4) when any LUN format described in this standard is used. Non-hierarchical formats are outside the scope of this standard. TGTD uses the two different LUN formats depending on whether the LUN number is <256 or not: 1, For LUNs < 256 See SAM4: 4.6.5 Single level LUN structure See the diagram at this section. 2, For LUNs >= 256 See SAM4: 4.6.8 Flat space addressing method See the diagram at this section. Since both LUN formats that TGTD uses is described in SAM4, therefore we should set the HiSup bit in the standard inquiry data.
