帮忙看看clstat不能用

# /usr/sbin/cluster/clstat
Failed retrieving cluster information.

There are a number of possible causes:
clinfoES or snmpd subsystems are not active.
snmp is unresponsive.
snmp is not configured correctly.
Cluster services are not active on any nodes.

Refer to the HACMP Administration Guide for more information.

我已经重启了snmpd  查看clinfoES已经启动，但还是不能有。不明白。收起
