为什么新加进来的LUN被加入到已存在的mpath设备而不是重新创建mpath设备?
加入新的LUN之前:[root@test ~]# multipath -ll 36005076802898138f40000000000000e dm-2 IBM,2145 [size=30G][features=1 queue_if_no_path][hwhandler=0][rw] \_ round-robin 0 [prio=0][active] \_ 1:0:0:1 sdb 8:16 [active][undef] \_ round-robin 0 [prio=0][enabled] \_ 0:0:0:1 sda 8:0 [active][undef] [root@test ~]#
加入新的LUN之后:
[root@gest]# multipath -ll
36005076802898138f40000000000000e dm-2 IBM,2145
[size=30G] [features=1 queue_if_no_path][hwhandler=0][rw]

\_ 1:0:0:1 sdb 8:16 [active][undef]
