一个超难的问题!!

我有一个问题：怎样修改hdisk*名
我想修改我的磁盘名hdisk23到hdisk25.
磁盘名hdisk23在 fastt上。

#lsdev -Cl hdisk14 -F 'class subclass type connwhere' -H
class subclass type  connwhere
disk  fdar     array 13

#lsparent -Cl hdisk14 -H
name status             location description
dar0 Available          1742     (700) Disk Array Router

#mkdev -p dar0 -t array -c disk -s fdar -w 13 -l hdisk27
Method error (/etc/methods/define):
0514-022 The specified connection is not valid.

我想可能是parentname和subclass有问题。

另外，我通过修改odm,也没有成功修改设备名。
那位有过相关经验，请告知！
急等！！！

另外，怎样用lsconn获得parentdevice？

i attempt to use this way to fix my problems, and the first stages seem ok, but i get the error when i creat a new vg on that hdisk14 whick  was changed with the new name, for example, hdisk17.
and when i delete the device name hdisk14 and associated odm information and creat a new disk on fastT and map the disk to my aix box, i found another problem. the old hdisk, for example, hdisk14 was still ocuppied the device name hdisk14 and the new disk has to use the hdisk15.but i alread delete the hdisk14 and odm information.
and i also get the error message with cfgmgr
could you tell me why?

reboot is the key problem.
otherwise,the /dev/rhdiskxx & /dev/hdiskxx will has the wrong name.
Maybe,you need to delete the /dev/*hdisk* which you want to change

my aix box is live production, so  i cant reboot it.
do you have another tip can fix it?

you are absolutely a expert!!!
i am waiting for the response!!!

Try use this:

Remember the major/minor number of the hdisk14:
brw-------   1 root     system    14,  7 Aug 06 21:38 /dev/hdisk14
crw-------   1 root     system    14,  7 Aug 06 21:38 /dev/rhdisk14

Remove the device link of the hdisk14
rm -f /dev/hdisk14
rm -f /dev/rhdisk14

Make a new device link for the hdisksunbeat14
cd /dev
mknod hdisksunbeat14 b 14 7
mknod rhdisksunbeat14 c 14 7
chmod 600 *hdisksunbeat14
