请问yddll,如你所说，那么分区的ID概念确实存在咯？

那又是何种原因导致楼主克隆系统出现了相同的ID呢？

这部分概念确实之前没有接触到，请明示，多谢多谢！

这个ID不是分区ID，是节点ID，由于使用了clone安装，每个系统的ct_node_id是一样的，这样基于RSCT的DLPAR就不能正确的识别不同的节点，所以需要更改这个ID

其实我的问题是什么情况下的克隆会出现这种情况，还是所有情况的alt_disk_install都会出现？

因为印象里面没有因为克隆分区所以不能做动态LPAR的事情发生，所以对这部分不太了解。

再或者把问题调整成关于ct_node_id，我该去看哪本书？

RSCT?

找到相关的解释了，如下：

After alternate disk install cloning, improper hostname resolution may cause HMC RSCT errors
Abstract
A properly defined system hostname is critical for RSCT function. This TIP reminds you that cloning can cause hostname resolution problems.


  
Contents
  
Dynamic LPAR relies on Service Focal Point and RSCT. This means that TCP/IP, including the hostname on the HMC, must be configured. The /etc/hosts files in the HMC and all LPARs must have entries for all entities with the hostname appearing first in any list of aliases.

A problem with DLPAR can exist after using the altinst_rootvg cloning procedure to create the second LPAR. The file /etc/ct_node_id had the same contents on both LPARs so RSCT may detect only one LPAR to manage. Development is aware of this and is working on a circumvention and correction. In the meantime, a workaround is to run the following two commands after the first boot of the new LPAR:
/usr/sbin/rsct/install/bin/uncfgct -n
/usr/sbin/rsct/install/bin/cfgct

A subsequent reboot will cause the partitions to be synchronized from an RSCT perspective. The duplicate /etc/ct_node_id condition are likely to cause negative behaviors in a HACMP scenario between cloned LPARs. Cloning an LPAR with a mksysb tape/DVD will likely cause the same problem. NIM installs avoid this problem as a unique /etc/ct_node_id file is created.  

另外，以下是alt_disk_install OBC参数的含义：
-O Performs a device reset on the target altinst_rootvg. This will cause alt_disk_install to NOT retain any user defined device configurations. This flag is useful if the target disk or disks will become the rootvg of a different system (such as in the case of logical partitioning or system disk swap).

-B Would specify not running bootlist after the mksysb or clone. If set, then -r flag cannot be used.

-C Clone rootvg.  

所以，综合来看，应该是楼主没有使用OBC参数导致，大家意下如何？

另，yddll，多写几个字可以么？如你上书5字符有太多含义可以解释了，谢谢！
