iscsi 碰到的一个奇怪的故障

iscsi Server : 192.168.1.100

iscsi Client101 : 192.168.1.101

iscsi Client101 : 192.168.1.102

在Server上有一个磁盘柜,放了4块2T SAS 硬盘组的RAID 10 ,共4T. 用于ORACLE 数据库组RAC ASM的.

配置文件:

cat /etc/tgt/targets.conf


include /etc/tgt/szqs/*.conf
include /etc/tgt/oracle/*.conf

cat /etc/tgt/oracle/oracle.conf

<target iqn.2017-02.szqs.oracle.storge:server.target1>
    #backing-store /dev/sda
    direct-store /dev/sda
    initiator-address 192.168.1.101,192.168.1.102
    incominguser user passwd
    write-cache on
</target>

故障重现

/etc/init.d/tgtd reload
OR
/etc/init.d/tgtd restart
都 OK
tgt-admin --show

也可以看到 target已ready

Target 3: iqn.2017-02.szqs.oracle.storge:server.target1
    System information:
        Driver: iscsi
        State: ready
    I_T nexus information:

但是在Client就是不能发现这个target,可以发现其它的.

故障解决

把配置文件修改为:
<target iqn.2017-02.szqs.oracle.storge:server.target1>
        #backing-store /dev/sda
        direct-store /dev/sda
        initiator-address 192.168.1.0/24  #这里修改后
        incominguser user passwd
        write-cache on
    </target>

Client就能成功发现了
