unh_iscsi-1.7.00的Initiator和Target通讯配置

target端

root@netstore:/opt/unh/iscsi/src/cmd# ./iscsi_manage target set TargetPortalGrou
pTag=1 host=$HBA

unh_iscsi中host指什么？ ******************重要**********************

Host=number是用来指出initiator端由kernel分配的scsi 适配器号，设置时可在客户端的相应文件路径/proc/scsi/iscsi_initiator下找到相应的説明，实际上儅机器上没有scsi设备时，host/target number会被指定为0，否则为1。

另外只有在insmod unh_iscsi_initiator命令之后，/proc/scsi/目录后才会出现iscsi_initiator文件夹以及它后面的表示host的数字。这正说明了Host=number是用来指出initiator端由kernel分配的scsi 适配器号，也就是硬盘分区号。
