purescale删除备cf后，无法使用db2instance -list

由于需要将CF的硬件切换为更高性能的设备，停止集群后，
在节点suse11sp3-135上：
1.执行db2idupt -drop -cf suse11sp3-117 db2sdin1 成功删除后
2.再执行db2idupt -add -cf suse11sp3-115 -cfnet suse11sp3-115ib db2sdin1
报错suse11sp3-135节点的/etc/dat.conf预检查失败。经确认该dat.conf文件内容与集群正常时内容一致。

且执行db2instance -list 时报错：
The member, CF, or host information could not be obtained.  Verify the cluster manager resources  are valid by entering db2cluster -cm -verify -resources.  Check the db2diag.log for more information.
db2diag.log 内容如下：
