sapinst.exe SAPINST_USE_HOSTNAME=<virtual hostname of (A)SCS instance>

Hi all,

For starting installation on HA systems with following command INST_USE_HOSTNAME=<virtual hostname of (A)SCS instance>

<virtual hostname of (A)SCS instance> points to SAP<SID> or GPSYSTEM ?

GPSYSTEM is name of virtual host created during MSCS , or SAP<SID> which is created for A(SCS)..

Which is used for starting , However i have started with GPSYSTEM, resulting in some issues, therefore is suspect. Please advice.
