  • The SAP system consists of several instances on different servers.
  • sapcontrol -nr <instance number> -function GetSystemInstanceList returns the instance list only partly, but some of the are missing.

For example,
in SM51 following three instances appear:

<host1>_<SID>_00 <host1> Dialog Batch Update Upd2 Spool ICM Active
<host2>_<SID>_00 <host2> Dialog Batch Update Upd2 Spool ICM Active
<host3>_<SID>_00 <host3> Dialog Batch Update Upd2 Spool ICM VMC Active

GetSystemInstanceList webmethod returns only two of them, the third one is missing:

sapcontrol -nr 0 -function GetSystemInstanceList

GetSystemInstanceList
OK
hostname, instanceNr, httpPort, httpsPort, startPriority, features, dispstatus
<host1>, 0, 50013, 50014, 3, ABAP GATEWAY ICMAN IGS, GREEN
<host2>, 0, 50013, 50014, 3, ABAP GATEWAY ICMAN IGS, GREEN

It can also happen that all the available instances are recognized by SUM but none of them is treated as "central instance".
