ADSDM175 2455 INVALID SYSPARM (RETMULTI) IN SYSPARMS MEMBER OR ON SYSPARMS DD                                                       
ADSDM175 2455 SYSPARM IS NO LONGER VALID. REMOVE THE INVALID SYSPARM                                                                

The solution is to remove the obsolete parameter RETMULTI from the SYSPARMS member used by DMSAR and rerun the DMSAR INSTALL. This sysparm  has been removed in DISK 12.5 by the GA PTF SO10594 .
