Hi Vivek,
the link you posted is an old guide and should only be used for SAP HANA SP4. Since SAP HANA SP6 has been out for months please always use the latest guides which uses HANA Lifecycle Manager to update SAP HANA: http://help.sap.com/hana_platform/#section2
If you use the guide you posted to update or install SAP HANA SP6 you will have an incomplete installation.
Regards,
Serge
