(w/softupdate) It seems that my istgt corrupted. Then, when I was going to have made the digest function effective for diagnostic, I encountered a further problem. iSCSI initiator(2.1.1) crashed when HeaderDigest was specified and the connection was tried. (DataDigest caused the system to hang) Has not it been supported yet? Note: istgt's digest function was tested by Microsoft's initiators. HeaderDigest was also tested by Open-iSCSI initiator (CentOS 5.2). This is another question. Is the following code an expected code? Why is Head of Queue tag mapped to Ordered Queue tag attribute? /usr/src/sys/dev/iscsi/initiator/iscsi_subr.c > case MSG_SIMPLE_Q_TAG: cmd->attr = iSCSI_TASK_SIMPLE; break; > case MSG_HEAD_OF_Q_TAG: cmd->attr = iSCSI_TASK_ORDER; break; > case MSG_ORDERED_Q_TAG: cmd->attr = iSCSI_TASK_HOFQ; break; > case MSG_ACA_TASK: cmd->attr = iSCSI_TASK_ACA; break; Thanks, -- Daisuke Aoyama
