客户新装AIX操作系统，需要将Netapp的存储映射到系统中，安装好Netapp MPIO后，发现多路径有问题，重装多路径软件后，系统识别lun正常，但是多了很多defined的信息，和 lsdev: 0514-521 Cannot find information in the predefined device         

configuration database for the customized device hdisk2 的报错信息

 解决思路如下：

删除磁盘时，报错：

#rmdev -Rdl hdisk12
rmdev: 0514-521 Cannot find information in the predefined device
configuration database for the customized device hdisk12.

　　这时我们需要删除ODM中的注册信息，才能够正常的删除磁盘

 

(root)#odmget -q name=hdisk19 CuAt OK
(root)#odmget -q name=hdisk19 CuDv

CuDv:
name = "hdisk19"
status = 1
chgstatus = 2
ddins = "scdisk"
location = "20-58-3L-4,12"
parent = "fcp0"
connwhere = "4,12"
PdDvLn = "disk/fcscsi/SYMM_BCV"
(root)#odmdelete -q name=hdisk19 -o CuDv --need to delete
1 objects deleted
(root)#odmget -q value3=hdisk19 CuDvDr

CuDvDr:
resource = "devno"
value1 = "21"
value2 = "19"
value3 = "hdisk19"
(root)#odmdelete -q value3=hdisk19 -o CuDvDr --need to delete
1 objects deleted
(root)#ls -l /dev | grep hdisk19
brw------- 1 root system 21, 19 Sep 14 2006 /dev/hdisk19
crw------- 1 root system 21, 19 Sep 14 2006 /dev/rhdisk19
(root)#rm /dev/hdisk19 /dev/rhdisk19

　

然后查看恢复正常
