Hi SAP,
Please follow SAP Note 1171534 .This note is meant for DB6 but follow Installation Process for it mentioned:
Installation of an MCOD system:
During an MCOD installation, you receive the following error when SAPinst creates the user SAPService<SAPSID>. In the 'sapinst_dev_log', you look for entries like the following:
FSL-01027 Account group="<domain>\DB2ADMNS_<SAPSID>" does not exist.
To avoid this error, you must create group <domain>\DB2ADMNS_<SAPSID> temporarily before you start SAPinst.
After the installation, this group only contains the user SAPService<SAPSID> of your MCOD system. Remove the user from the group and delete this group ONLY if is empty.
Hope this will help you.
Regards,
Gaurav
