Fwd: Multiple host in hosts.cfg

[spdesai at gnvfc.net]

GOOD EXPLANATION FROM YR SIDE.

SO IF I WANT TO ADD MORE HOSTS THEN I NEED TO ADD IN ONLY HOSTS.CFG FILE NOT 
IN ANY OTHER FILE(LIKE SERVICE/HOSTGROUPS ETC)AS OTHER FILES ARE LOOK HOSTS 
DETAILS FROM HOSTGROUP NAME.

RIGHT ?

PL. CONFIRM ..

THANKS FOR YR SUPPORT

THANKS AND REGARDS,
SUHAG DESAI
