Using this sysparm can cause adverse affects on SMS managed data sets. In situations where you don't want to keep multiple archive DSNINDEX records (that is, after restore) to the expiration date as defined by the management class, this sysparm should be set to a non-default value. This is because, CA Disk does not review the number of archive copies, only backup ones.
However, using this sysparm on an SMS managed data set will sever the relationship between DFSMS and the data set. The result is that all further CA Disk processing of the data set (including MERGE and IXMAINT) will be done using only CA Disk rules based upon the expiration date calculated from this sysparm value (that is, MERGE will ignore its Management Class attributes when determining whether or not to merge the data set based upon level 1 days).
