如何显示 iSCSI 配置信息

1. 成为管理员。
2. 显示有关 iSCSI 启动器的信息。

   例如：

   # iscsiadm list initiator-node
   Initiator node name: iqn.1986-03.com.sun:01:0003ba4d233b.425c293c
   Initiator node alias: zzr1200
           Login Parameters (Default/Configured):
                   Header Digest: NONE/-
                   Data Digest: NONE/-
           Authentication Type: NONE
           RADIUS Server: NONE
           RADIUS access: unknown
           Configured Sessions: 1

3. 显示有关当前使用的搜索方法的信息。

   例如：

   # iscsiadm list discovery
   Discovery:
   	Static: enabled
   	Send Targets: enabled
   	iSNS: enabled

以下示例说明如何显示特定 iSCSI 目标的参数值：

# iscsiadm list target-param iqn.1992-08.com.abcstorage:sn.33592219
        Target: iqn.1992-08.com.abcstorage:sn.33592219

iscsiadm list target-param -v 命令显示以下信息：

• 目标的验证值

• 目标登录参数的缺省值

• 每个登录参数的已配置值

iscsiadm list target-param -v 命令在 / 指示符前显示缺省参数值，并在 / 指示符后显示已配置参数值。如果未配置任何参数，其值将显示为连字符 ( -)。有关更多信息，请参见以下示例。

# iscsiadm list target-param -v eui.50060e8004275511 Target: eui.50060e8004275511
        Alias: -
        Bi-directional Authentication: disabled
        Authentication Type: NONE
        Login Parameters (Default/Configured):
                Data Sequence In Order: yes/-
                Data PDU In Order: yes/-
                Default Time To Retain: 20/-
                Default Time To Wait: 2/-
                Error Recovery Level: 0/-
                First Burst Length: 65536/-
                Immediate Data: yes/-
                Initial Ready To Transfer (R2T): yes/-
                Max Burst Length: 262144/-
                Max Outstanding R2T: 1/-
                Max Receive Data Segment Length: 65536/-
                Max Connections: 1/-
                Header Digest: NONE/-
                Data Digest: NONE/-
        Configured Sessions: 1

以下示例输出显示了目标与启动器之间协商的参数：
