[Docs] PERSMAPI Documentation Gap for "Get host info " API

[dvjsharma]

Summary

The "Get host info" API call (GET /host) fails with SMAPI reason code 3016 ("SMAPIOUT segment empty") when PERSMAPI (Performance SMAPI) server is not logged on, but current Feilong documentation lacks proper prerequisites to prevent this issue.

Expected Behavior

• Documentation should clearly state PERSMAPI logon requirement
• Pre-requirements section should include PERSMAPI setup steps
• API should either work correctly or provide clear error guidance

Steps to Reproduce

1. Set up Feilong environment without ensuring PERSMAPI is logged on
2. Call GET /host API through SDK or REST interface
3. Observe SMAPI error 3016 response

For whoever might want to track the function calls:

1. API call GET /host
2. calls def get_info(self)
   in file zvmsdk/hostops.py
3. calls def get_host_info(self)
   in file zvmsdk/smtclient.py
4. calls getGeneralInfo(rh)
   in file smtLayer/getHost.py
5. does
   results = invokeSMCLI(rh, "System_Performance_Information_Query", parm)
6. runs
   /opt/zthin/bin/smcli System_Performance_Information_Query --addRCheader -T dummy -k detailed_cpu=show=no

This last command fails in the conditions exposed in the description above.

Hope that helps.
