问题：
1、上面的输出能否看到主机装了几个hba卡，每个hba卡的id是多少？
2、上面是输出中是否是4条path？
3、hdev设备sddlmaa 是否是有四个基盘 /dev/sdb 、/dev/sdg 、 /dev/sdd 、 /dev/sdf组成吗？
4、hdev设备sddlmaa只有一个逻辑分区/dev/sddlmaa1，为什么# ll /dev/sddlma*命令输出又那么多呢？
上面的问题可能问的幼稚，请不要拍砖，没有办法，绝对的新手，谢谢！ 两个LUN，每个LUN可以通过4个Path扫描到，通过阵列的四个端口：0A/0B/1A/1B。 两个LUN，每个LUN可以通过4个Path扫描到，通过阵列的四个端口：0A/0B/1A/1B。

谢谢回复，那就是有4个hba卡，，那对应的hba卡的id能否看到呢？
第3、4个问题呢，还烦请赐教,谢谢！ 第四个问题应该是这样的：fdisk -l /dev/sddlmaa输出中显示hlu设备sddlmaa只有一个逻辑分区hdev /dev/sddlmaa1，为什么# ll /dev/sddlma*命令输出又那么多呢？vgscan命令输出显示hlu sddlmaa至少有两个hdev：/dev/sddlmaa1和/dev/sddlmaa2. # /opt/DynamicLinkManager/bin/dlnkmgr view -path -iem -hbaportwwn

这里的输出也看到HBAPortWWN只有一个，另外一个hba连接的path出现错误，为什么有4个path，而只有两个hba卡呢 路过的高手，请赐教！ 两个LUN，每个LUN可以通过4个Path扫描到，通过阵列的四个端口：0A/0B/1A/1B。

下面的输出是不是阵列端东东？就是和hba连接的存储设备？

按您的意思，但实际是系统有两个lun，被4个path扫描的到，cha的port是0A/0B/1A/1B，对应应该也是4个hba才对啊，但上面查询到的是2个hba卡！求解
