Hi Ajitabh,
From the error message
NW_ABAP_OneHost|ind|ind|ind|ind|0|0|NW_Onehost_System|ind|ind|ind|ind|onehost|0|NW_System|ind|ind|ind|ind|system|0|NW_SAPHostAgent|ind|ind|ind|ind|hostagent|0|createAccounts was executed with status ERROR ( Last error reported by the step: Invalid password. DIAGNOSIS: The password you specified for user 'sap\sapadm' is wrong. SOLUTION: Enter the correct password.).
Please ensure you are doing the following
1) Entering correct password as per the guidelines appearing on the sapinst screen
2) Password does not contain any special characters
I had faced a similar issue and was resolved by putting password without any special characters.
Hope this helps.
