Hmm, looks like the initiator sent SAI_READ_CAPACITY_16 (77th packet). I thought even very old STGT can handle this (you use 20070620) because the code is based on IET but I might be wrong. Try the latest STGT, http://stgt.berlios.de/releases/tgt-0.9.3.tar.bz2 With it and open-iscsi, I got: scsi0 : iSCSI Initiator over TCP/IP scsi 0:0:0:0: RAID IET Controller 0001 PQ: 0 ANSI: 5 scsi 0:0:0:1: Direct-Access IET VIRTUAL-DISK 0001 PQ: 0 ANSI: 5 Driver 'sd' needs updating - please use bus_type methods sd 0:0:0:1: [sda] Very big device.
