  • 1.  Server discovery not working

    Posted 08-05-2022 01:57
    Hello All,

    I am trying to run server discovery but its getting finished without any server discovered.
    The database is SAP HANA database.

    Previously it was working fine but when I am trying after 10-15 days. Its giving no result.
    I tried to run tcpdump on MX during server discovery process. I am not seeing any traffic on SAP HANA port (30015).

    Please help to solve this issue.

    Hi Ashutosh,

    Thanks for posting.

    Check the global object port list. Verify the appropriate port list is selected in the site tree server group.

    From the MX CLI run nmap <ip addr > -p 30015 of a known SAM HANNA server, to see if the port is blocked.

    Let me know how it goes.

    Hi Ashutosh,

    The results of the nmap command may be correct in showing no listening on port of 30015. I invite you to use this nmap command nmap <ip addr> -Pn -p 30015 from the MX that will do the scan. If the results do show the port open, please review the network discovery scan settings.
    Thank you.
