Can not connect to SAPRouter after OS/DB Migration

Question

Dear Expert,
After did OS/DB migration from Solaris to HP-UX we have same problem with the saprouter. I try to connect to saprouter via SM59 (test connection) but I cannot create a connect and the error say partner not reached (host 172.31.1.34, service sapdp99). I old system we can make a connection through SM59.
I also tried to see the log error in ST11 and below is the result:
Error RFCIO_ERROR_SYSERROR in abrfcpic.c : 2467                                     
LB: Hostname or service of the message server unknown                               
DEST =SAPOSS                                                                        
MSHOST =/H/172.31.1.34/S/sapdp99/H/194.39.131.34/S/sapdp99/H/oss001                 
R3NAME =OSS

I also have made some changes in file saprouttab in sap router server. I have added the ip address of my new SAP server, but error same. Can you tell me what things I miss to do?
Thank you for your help.

Answer 1

i can ping the saprouter server. I have compare the services in  old and new server. There are some services missing in my new SAP Server. Below the services available in both system:
old server
   sapmsRP1        3600/tcp        # SAP System Message Port
   sapdp00 3200/tcp        # SAP System Dispatcher Port
   sapdp00s        4700/tcp        # SAP System Dispatcher Security Port
   sapgw00 3300/tcp        # SAP System Gateway Central Instance Port
   sapgw00s        4800/tcp        # SAP System Gateway Security Port
   sapdp01         3201/tcp        # SAP System Dispatcher Port
   sapdp01s        4701/tcp        # SAP System Dispatcher Security Port
   sapdp99         3299/tcp        # SAP System Dispatcher Port
   sapdp02         3202/tcp
   sapdp02s        4702/tcp
   sapgw02         3302/tcp        # SAP System Gateway
   sapgw02s        4802/tcp
   sapgw01         3301/tcp
   sapgw01s        4801/tcp        # SAP System Gateway Security Port
   sapgw03         3303/tcp        # SAP System Gateway Central Instance Port
   sapgw03s        4803/tcp        # SAP System Gateway Security Port
new server
   sapmsRP1        3600/tcp        # SAP System Message Port
   sapdp00 3200/tcp        # SAP System Dispatcher Port
   sapdp00s        4700/tcp        # SAP System Dispatcher Security Port
   sapgw00 3300/tcp        # SAP System Gateway Central Instance Port
   sapgw00s        4800/tcp        # SAP System Gateway Security Port
   sapdp99     3299/tcp      #SAP System DIspatcher Port
should i add the missing services in my new server? and should i keep the added-new server in  file saprouttab?
