 Here scripts to automate ILM
 https://github.com/IBM/spectrum-scale-policy-scripts
+Examples of policies:
+<cli>
+/* fileset placement project1 to new 10TB NL-SAS pool */
+RULE 'project1' SET POOL 'NLSAS10TB' FOR FILESET ('project1')
+/* fileset placement project2 to new 10TB NL-SAS pool */
+RULE 'project2' SET POOL 'NLSAS10TB' FOR FILESET ('project2')
+/* default placement to pool NLSAS4TB, must be the last line */
+RULE 'default' SET POOL 'NLSAS4TB'
+</cli>
+<cli>
+/* Extension of the placement policy by the threshold */
+RULE 'migrate_SSD2NLSAS_60' MIGRATE FROM POOL 'ssddata' THRESHOLD(60,50)
+WEIGHT(KB_ALLOCATED) TO POOL 'data'
+WHERE ((CURRENT_TIMESTAMP - MODIFICATION_TIME) > INTERVAL '5' MINUTES)
+/* Daily migration policy started by cron on the file system manager, with QoS */
+RULE 'migrate_SSD2NLSAS_128M' MIGRATE FROM POOL 'ssddata' TO POOL 'data' WHERE KB_ALLOCATED >
+AND ((CURRENT_TIMESTAMP - MODIFICATION_TIME) > INTERVAL '5' MINUTES)
+</cli>
+Add the callback to trigger the threshold migration on “lowDiskSpace”, without QoS
+<cli prompt='#'>
+# mmchconfig enableLowspaceEvents=yes
+# /usr/lpp/mmfs/bin/mmaddcallback MIGRATION --command /usr/lpp/mmfs/bin/mmstartpolicy --event lowDiskSpace --parms "%eventName %fsName -g /cfs/.policywdir/global -s /cfs/.policywdir/local -N nsdsrv --single-instance --qos other"
+</cli>
