I have changed the hostname in all the file (1) hostname ,(2)/etc/sysconfig/network file . i even checked my hostname and it shows hostname as "HOST1" so i am confused even though hostname is "HOST1" but in dev_ms the IP ADRESS is resolving to "host1.mycompanyname.com"
3. Also when i am trying to run "startsap" or "stopsap" from host1 where central service instance is installed. It gives me "command not found" although i see all the exe file in /usr/sap/SID/SYS/exe/run. why my command not running.
. I have added the sapmsSID 3900/tcp entries in both HOST1 and HOST3 services file.

Only that
When I grep on Error from the file I get
more sapinst_dev.log |grep error
