改存储使用multipath服务配置多路径聚合：
/etc/multipath.conf需配置如下：

IBM工程师
在/etc/multipath.conf文件中
添加如下内容：

defaults {

        user_friendly_names yes

}

devices {

device {

vendor "IBM"

product "2145"

path_grouping_policy group_by_prio

getuid_callout "/lib/udev/scsi_id --whitelisted --device=/dev/%n"

features "1 queue_if_no_path"

prio alua

path_checker "tur"

failback immediate

rr_min_io_rq 1

polling_interval 30

dev_loss_tmo 120

}

}

在/etc/multipath.conf文件中添加如下内容，使用wwid绑定磁盘：

multipaths {

   multipath {

           wwid        3600507680c8081320800000000000043 

           alias       crsa

   }

   multipath {

           wwid        3600507680c8081320800000000000041 

           alias       crsb

   }

   multipath {

           wwid        3600507680c8081320800000000000040

           alias       crsc        

   }

   multipath {

           wwid        3600507680c808132080000000000003f

           alias       crsd        

   }

   multipath {

           wwid        3600507680c8081320800000000000042        

           alias       crse        

   }

   multipath {

           wwid        3600507680c808132080000000000004b

           alias       dataa

   }

   multipath {

           wwid        3600507680c808132080000000000004a

           alias       datab

   }

   multipath {

   }

   multipath {

           wwid        3600507680c8081320800000000000049

           alias       datad

   }

   multipath {

           wwid        3600507680c8081320800000000000046

           alias       datae

   }

   multipath {

           wwid        3600507680c8081320800000000000045

           alias       dataf

   }

   multipath {

           wwid        3600507680c8081320800000000000047

           alias       datag

   }

   multipath {

           wwid        3600507680c8081320800000000000044

           alias       bak

   }

   multipath {

           wwid        3600507680c808132080000000000004c

           alias       fra

   }

   multipath {

           wwid        3600507680c808132080000000000004d

           alias       acfs
