先/opt/DynamicLinkManager/bin/dlmchname -o   生成文件/etc/opt/DynamicLinkManager/dlmchname.conf

然后修改/etc/opt/DynamicLinkManager/dlmchname.conf 里名字再  /opt/DynamicLinkManager/bin/dlmchname -f

然后reboot机器

1) Create a definition file:

/opt/DynamicLinkManager/bin/dlmchname -o

   [root@localhost ~]# /opt/DynamicLinkManager/bin/dlmchname -o

   KAPL12374-I This operation will change the HDLM device configuration. Do you want to continue? [y/n]:y

   KAPL12379-I The utility for changing HDLM device names finished normally.

2) The file will be at /etc/opt/DynamicLinkManager/dlmchname.conf. The content is similar to this:

    serial number LDEV ID HDLM device name.

   3585011299 0090 sddlmac

   3585011299 0091 sddlmab

   3585011299 0092 sddlmaa

   The columns are serial number, LDEV ID, and HDLM device name.

3) Modify the HDLM device names to whatever you want

4) Update HDLM using definition file: /opt/DynamicLinkManager/bin/dlmchname -f

5) Reset the server Reboot

6) Copy the definition file to other servers in the cluster and run steps 4 & 5.
