iSCSI 目標啟動器位址的通配符 IP 位址似乎在 CentOS 6 上不起作用

通配符/etc/tgt/targets.conf( 172.16.2.*) 不適用於啟動器位址。我正在準備紅帽高可用性集群考試 (EX436)。

學生作業本上寫道：

使用命令，如果需要，tgtadm您可以在選項中使用通配符，例如 172.16.X.* 。--initiator-address

但這是targets.conf不適用於通配符的配置：

# cat /etc/redhat-release 
CentOS release 6.6 (Final)

# rpmquery scsi-target-utils
scsi-target-utils-1.0.24-16.el6.x86_64

# cat /etc/tgt/targets.conf
....
<target iqn.2015-09.rhel6.storage1>
    backing-store /dev/mapper/vg_rhel6-clustorage1
    vendor_id ex436prep
    initiator-address 172.16.2.*
</target>

# tgt-admin -s
Target 1: iqn.2015-09.rhel6.storage1
    System information:
        Driver: iscsi
        State: ready
    I_T nexus information:
    LUN information:
        LUN: 0
            Type: controller
            SCSI ID: IET     00010000
            SCSI SN: beaf10
            Size: 0 MB, Block size: 1
            Online: Yes
            Removable media: No
            Prevent removal: No
            Readonly: No
            Backing store type: null
            Backing store path: None
            Backing store flags: 
    Account information:
    ACL information:
        172.16.2.*

但是當我在 中設定initiator-address發起者的 IP 位址 ( 172.16.2.10)時targets.conf，一切都按預期工作：

# cat /etc/tgt/targets.conf
...
<target iqn.2015-09.rhel6.storage1>
    backing-store /dev/mapper/vg_rhel6-clustorage1
    vendor_id ex436prep
    initiator-address 172.16.2.10
</target>

# tgt-admin -s
Target 1: iqn.2015-09.rhel6.storage1
    System information:
        Driver: iscsi
        State: ready
    I_T nexus information:
        I_T nexus: 1
            Initiator: iqn.2015-09.one:i1
            Connection: 0
                IP Address: 172.16.2.10
    LUN information:
        LUN: 0
            Type: controller
            SCSI ID: IET     00010000
            SCSI SN: beaf10
            Size: 0 MB, Block size: 1
            Online: Yes
            Removable media: No
            Prevent removal: No
            Readonly: No
            Backing store type: null
            Backing store path: None
            Backing store flags: 
        LUN: 1
            Type: disk
            SCSI ID: IET     00010001
            SCSI SN: beaf11
            Size: 2076 MB, Block size: 512
            Online: Yes
            Removable media: No
            Prevent removal: No
            Readonly: No
            Backing store type: rdwr
            Backing store path: /dev/mapper/vg_rhel6-clustorage1
            Backing store flags: 
    Account information:
    ACL information:
        172.16.2.10

答案1

下面的方法就成功了！

initiator-address 172.16.2.0/24
