故障：
SLP复制问题，异常状态码191（V-454-92,V454-105）
解决方案：
1.检查本端的puredisk情况，正常
2.检查对端puredisk情况，如10.35.53服务的防火墙和selinux及puredisk情况，发现puredisk异常
3.登录对端NBU服务器上，运行命令如下：
# /usr/openv/pdde/pdcr/bin/crcontrol –getmode
Error: -1: NetConnectByAddr: Failed to connect to host: Connection refused (111)
Error: -1: NetConnectByAddr: Failed to connect to spoold on port 10082 using the following interface(s): [ ::1 ] (Connection refused) Ensure storage server services are running and operational. V-454-92
Error: 53: Could not establish a connection to ::1:10082: connect failed (Connection refused)
Error : Connection failed connection actively refused. Note that the content router needs to be running to get a connection.
4.关闭防火墙和selinux和检测hosts解析情况，查看pool状态及挂载点参考上面
5.查看pool的状态 > # nbdevquery -listdp -U -dp <pool_name> ，状态为DOWN
6.查看是否处于挂载 > # df -h ，没有看到挂载，下图查看挂载目录
7.查看挂载目录权限，修改为755
# chmod 755 msdpdata
# chmod 755 msdpcat
