我有一个pyTarget iSCSI目标。 我可以使用iPXE连接到目标并安装Ubuntu。 安装后，我无法启动到图像，但是。
pyTarget config.xml：
<root> <!-- configure target console --> <console ip="" port="3260" debug_level="6" /> <!-- configure the first target --> <target name="iscsi" ip="192.168.1.10" port="3260" portal="1"> <!-- the first iqn of this target configured for disk array --> <host name="iqn.2006-11.1" target_pwd="" initiator_pwd=""> <lun id="0" type="0" path="E:\pyTarget\ubuntu16.ima" capacity="81943040" /> </host> </target> </root> pyTarget控制台在启动时：

安装完成后，我尝试启动映像：
COMMAND: SCSI Request COMMAND: Write(10) LBA:0x1c40800 LEN:0x8 LUN:0 COMMAND: SCSI Request COMMAND: Write(10) LBA:0x1c40800 LEN:0x8 LUN:0 COMMAND: SCSI Request COMMAND: Write(10) LBA:0x1c40800 LEN:0x8 LUN:0 COMMAND: SCSI Request COMMAND: Write(10) LBA:0x1c40800 LEN:0x8 LUN:0 COMMAND: SCSI Request COMMAND: Write(10) LBA:0x800 LEN:0x8 LUN:0 COMMAND: SCSI Request COMMAND: Test Unit Ready LUN:0 COMMAND: SCSI Request COMMAND: Test Unit Ready LUN:0 # Install ends here # Client restarts, attempts to boot to the new install: DEBUG: create connect INFO: initiator 192.168.1.15:30733 connect. NEGOTIATION: SessionType = Normal WARNING: initiator name or target name is INVAILD iqn.2006-11.1 DEBUG: connect 0 finish.
掉到iPXEshell并尝试手动sanboot ，它吐出了额外的信息 – 这个错误 ：
(Error code 3c0d61) This error originated from one of the following locations within the iPXE source code: net/tcp/iscsi.c (line 1226) This error indicates an unexpected status received from the iSCSI target.
Wireshark有以下几点：
客户端将iSCSI LOGIN命令发送到主机，值得注意的内容：
Key/Value Pairs KeyValue: InitiatorName=iqn.2006-11.1 KeyValue: TargetName=iqn.2006-11.1 KeyValue: SessionType=Normal KeyValue: AuthMethod=CHAP,None
主机返回iSCSI LOGIN响应，值得注意的内容：
Status: Missing parameter (0x0207)
这个错误代码在这个邮件列表中被简要地讨论，但是我不够明白它的意义。
我不明白目标或发起人的名字怎么会突然失效？ 也不缺什么参数。 连接实际上只是在使用中，并没有在安装过程中的投诉…我甚至可以复制这一点 – 再次开始安装不是一个问题，并完成就好（再次）。 而重新安装后，当我尝试启动相同的问题！
我可以注意到的一件事是，在iSCSI或PXE中，空密码有些奇怪。 在ubuntu安装过程中，为了完成iSCSI卷的login，我必须按空格键一次 – 它不接受NULL长度的密码，即使密码在configuration中本质上是NULL。
但是，在iPXE中不能inputSPACE作为密码 – 唯一的空白空间似乎被认为是NULL。 但是，将initiator_pwd设置为非NULL不会有帮助。
现在我已经坚持了几个小时。 我在哪里从这里进行更多的故障排除？
编辑：忘了补充：
iPXEconfiguration：
#!ipxe set iscsi-target iscsi:192.168.1.10::::iqn.2006-11.1 set gateway 0.0.0.0 set initiator-iqn iqn.2007-11.1 set keep-san 1 sanboot ${iscsi-target} boot
新的config.xml
<!-- configure the first target --> <target name="iscsi" ip="192.168.1.10" port="3260" portal="1"> <!-- the first iqn of this target configured for disk array --> <host name="iqn.2006-11.1" target_pwd="1" initiator_pwd="1"> # <-- Set passwords to avoid NULL problem, this comment was not part of the actual config <lun id="0" type="0" path="E:\pyTarget\ubuntu16.ima" capacity="81943040" /> </host> </target>
脚本失败后丢弃iPXE shell：
1. dhcp 2. login username: iscsi password: 1 3. sanboot iscsi:192.168.1.10::::iqn.2006-11.1
新的数据包捕获：

sanboot iscsi:192.168.1.10::::iscsi返回Status: Authentication failed (0x0201) wireshark中的Status: Authentication failed (0x0201)和客户端控制台中的相应操作不允许410d61 。
pyTarget控制台：
DEBUG: create connect DEBUG: destroy connect 0 INFO: initiator 192.168.1.15:1552 connect. NEGOTIATION: SessionType = Normal NEGOTIATION: TargetName = iscsi WARNING: InitiatorName %s do not exist. iqn.2007-11.1 DEBUG: connect 0 finish.
最后的错误信息翻转了指示灯。 不好意思，我倒了个名字：
在iPXE shell中：
set initiator-iqn iqn.2006-11.1 sanboot iscsi:192.168.1.10::::iscsi
现在我开机了
为了说明，iPXEconfiguration工作如下所示：
#!ipxe set iscsi-target iscsi:192.168.1.10::::iscsi set gateway 0.0.0.0 set initiator-iqn iqn.2006-11.1 set keep-san 1 sanboot ${iscsi-target} boot
