搭建的HACMP测试环境为AIX 6.1，两节点，目前服务启停，RG切换等都正常，/usr/es/sbin/cluster/clstat运行也正常
服务检查也是正常的：

lssrc -a|egrep "ES|vcs"

clcomdES clcomdES 7078140 active
clstrmgrES cluster 5701846 active
topsvcs topsvcs 22675648 active
grpsvcs grpsvcs 21102736 active
emsvcs emsvcs 23003340 active
clinfoES cluster 8519760 active
grpglsm grpsvcs inoperative
emaixos emsvcs inoperative
，唯一在运行smit hacmp->Problem Determination Tools-->Problem Determination Tools时，提示
Command: failed stdout: yes stderr: no

Before command completion, additional instructions may appear below.
