卸载StorageControl4.2.2.X出错

今天要重装System Director6.3.1, 首先要把plug-in StorageControl删除，进入StorageControl目录，运行./UninstallStorageControl.sh，结果出现如下错误：

# ./UninstallStorageControl.sh

Exception in thread "main" java.lang.NoClassDefFoundError: DisplayMessage

Caused by: java.lang.ClassNotFoundException: DisplayMessage

思考一下，不知缘由，打开UninstallStorageControl.sh研究一下好了。

脚本开始定义了一堆函数，然后第一步运行的是：

setJavaPath

看这个函数:

function setJavaPath

{

   lslpp -l "DirectorServer" >> $LOGFILE 2>&1

   if [ $? -ne 0 ] ; then

     return 1

   fi

   if [ -f /etc/ibm/director/twgserver/twgserver ] ; then

     DIRHOME=$(cat /etc/ibm/director/twgserver/twgserver|grep TWG_ROOTDIR|awk -F"=" '{print $2}')

     DB2USER=$(grep rcs.dbuser $DIRHOME/lwi/conf/overrides/database.properties  | awk '{print $3}')

   else

      return 1

   fi

   JAVAPATH=$DIRHOME/jre/bin

   CLASSPATH=$DIRHOME/StorageControl/lib/eTPCInstallTools.jar:$CUR_LOC/eTPCInstallTools.jar

   return 0

}

看设置java环境变量部分：

CLASSPATH=$DIRHOME/StorageControl/lib/eTPCInstallTools.jar:$CUR_LOC/eTPCInstallTools.jar

结果发现在StorageControl目录下没有lib这个目录， $CUR_LOC目录下也没有这个jar包，看来是当初安装的时候就有问题，没安装全。于是跑到另外一个装了StorageControl的机器上，拷贝过来lib目录，再重新运行UninstallStorageControl.sh， 成功~~
