240 IBM Content Manager OnDemand Guide
10.6.2  Storage Manager expiration 
ASM is the process for performing Storage Manager-based expiration. ASM performs the 
following functions:
/SM590000Controls the expiration of indexes and data from Content Manager OnDemand (if you use 
Storage Manager-based expiration)
/SM590000Aggregates data before it migrates it to archive media (if you select the Aggregation option 
in the migration policy)
/SM590000Moves data between storage levels of the migration policy
If you do not run ASM, your disk storage requirements for Content Manager OnDemand are 
probably higher than expected. The number of objects that are stored in the IFS is also higher 
than necessary, which results in longer save and restore times.
If you never run ASM, the first execution of the Start Archived Storage Management 
(STRASMOND) command or the Start Disk Storage Management (STRDSMOND) command with 
the STRASMOND parameter set to YES might last for an extended period.
