2.分析报错内容

2.1 报错对象

四个磁盘符如下：

sde

sdae

sdar

sdat

2.2 lsblk查看

有四块512B大小的磁盘分别是：

sde sdae sdar sdat

和上面IO报错是吻合的磁盘符

[root@redhat log]# lsblk

2.3 multipath查看

multipath -ll

没有发现上述四个磁盘在用。

2.4 检查盘健康状态

发现该盘是来自于没有在使用的3par，仅仅只是在3par上加了该主机，根本没有映射VV过来。

2.5 3par查看

发现其主机persona角色设置为VMware而不是redhat对应的Generic-ALUA，所以虽然没有对应大小的磁盘，但是vmware角色默认会产生一些校验类似的盘，这些磁盘符是读不了的，但是redhat内核下会不间断去尝试读一下盘检查状态。所以就产生了dmesg里面的报错信息。

而修改主机的persona需要重启系统，不然只是重新扫描scsi磁盘的话这几个512B的盘仍然存在。

而wwn在线的情况下直接修改不了persona。

如果没有盘在挂载的情况下，可以remove主机+create主机的步骤。

如果有挂载的情况下，则需要关机+修改persona。

                          51402EC0155358A8 0:0:1

3.结论

在3par存储上设置角色一定要设置对应正确的格式，不然会有未知的报错信息。
