一、功能需求

Linux 系统下Veritas Storage Foundation识别的dmpdev磁盘如何和存储LUN进行对应?

[root@cent6u8 /]# vxdmpadm list dmpnode aluadisk0_41
dmpdev		= aluadisk0_41
state		= enabled
enclosure	= aluadisk0
cab-sno		= 0x00b3420f-0f8d0000-
asl		= jbod
vid		= MacroSAN
pid		= LU
array-name	= aluadisk
array-type	= ALUA
iopolicy	= MinimumQ
avid		= -
lun-sno		= f9f9a445-fbf
udid		= MacroSAN%5FLU%5F0x00b3420f-0f8d0000-%5Ff9f9a445-fbf
dev-attr	= -
lun_type	= -
scsi3_vpd	= -
replicated	= no
num_paths	= 4
###path		= name state type transport ctlr hwpath aportID aportWWN attr
path		= sdmq enabled secondary FC c3 c3 - 50:0b:34:20:0f:0f:8b:09 -
path		= sdla enabled(a) primary FC c3 c3 - 50:0b:34:20:0f:0f:8d:09 -
path		= sdhu enabled(a) primary FC c2 c2 - 50:0b:34:20:0f:0f:8d:0b -
path		= sdjk enabled secondary FC c2 c2 - 50:0b:34:20:0f:0f:8b:0b -

二、问题分析

DMP在添加VID为宏杉存储作JBOD设备时，未添加serialnum参数，需要删除重新添加。

# vxddladm addjbod vid=MacroSAN cabinetnum=18/-1/96/20

三、配置步骤

1.删除vid=MacroSAN的JBOD磁盘类型

# vxddladm rmjbod vid=MacroSAN

# vxddladm addjbod vid=MacroSAN cabinetnum=18/-1/96/20 serialnum=18/131/8/16

3.结果确认，dmpdev磁盘的lun-sno与存储LUN WWN对应

[root@cent6u8 /]# vxdmpadm list dmpnode aluadisk0_41
dmpdev		= aluadisk0_41
state		= enabled
enclosure	= aluadisk0
cab-sno		= 0x00b3420f-0f8d0000-
asl		= jbod
vid		= MacroSAN
pid		= LU
array-name	= aluadisk
array-type	= ALUA
iopolicy	= MinimumQ
avid		= -
lun-sno		= 600B34202B5C107D42CCD9D89D0000D0
udid		= MacroSAN%5FLU%5F0x00b3420f-0f8d0000-%5F600B34202B5C107D42CCD9D89D0000D0
dev-attr	= -
lun_type	= -
scsi3_vpd	= -
replicated	= no
num_paths	= 4
###path		= name state type transport ctlr hwpath aportID aportWWN attr
path		= sdmq enabled secondary FC c3 c3 - 50:0b:34:20:0f:0f:8b:09 -
path		= sdla enabled(a) primary FC c3 c3 - 50:0b:34:20:0f:0f:8d:09 -
path		= sdhu enabled(a) primary FC c2 c2 - 50:0b:34:20:0f:0f:8d:0b -
path		= sdjk enabled secondary FC c2 c2 - 50:0b:34:20:0f:0f:8b:0b -
