hadr 启动备机HADR_LOCAL_SVC 端口号不在监听，db2diag.log 里面一直报错
MESSAGE : ZRC=0x810F0077=-2129723273=SQLO_COMM_ERR_EHOSTUNREACH
"No route to host"
主库配置的端口是55001，启动primary 端口就会处于监听状态
备考配置的55002，启动的时候检测不到55002的监听，端口号都是在/etc/service 文件配置的
primary：
db2 get db cfg for hadb |grep -i hadr
HADR database role = STANDARD
HADR local host name (HADR_LOCAL_HOST) = 192.168.254.110
HADR local service name (HADR_LOCAL_SVC) = DB2_HADR_1
HADR remote host name (HADR_REMOTE_HOST) = 192.168.254.111
HADR remote service name (HADR_REMOTE_SVC) = DB2_HADR_2
HADR instance name of remote server (HADR_REMOTE_INST) = db2inst1
HADR timeout value (HADR_TIMEOUT) = 120
HADR log write synchronization mode (HADR_SYNCMODE) = NEARSYNC
HADR peer window duration (seconds) (HADR_PEER_WINDOW) = 0
standby：
db2 get db cfg for hadb|grep -i hadr
HADR database role = STANDARD
HADR local host name (HADR_LOCAL_HOST) = 192.168.254.111
HADR local service name (HADR_LOCAL_SVC) = DB2_HADR_2
HADR remote host name (HADR_REMOTE_HOST) = 192.168.254.110
HADR remote service name (HADR_REMOTE_SVC) = DB2_HADR_1
HADR instance name of remote server (HADR_REMOTE_INST) = db2inst1
HADR timeout value (HADR_TIMEOUT) = 120
HADR log write synchronization mode (HADR_SYNCMODE) = NEARSYNC
HADR peer window duration (seconds) (HADR_PEER_WINDOW) = 0
大家帮忙分析一下有可能是什么原因导致的，谢谢！
