Lizette, If you are collection type 19 records then every switch will have to "touch" all online DASD volumes for information. So the more online DASD the longer the switch. We never did anything with the SMF 19's so we don't collect them at all anymore. On our busy PROD lpar with about 10K online DASD it still only takes about 3 seconds for a switch to complete.

I was wondering on a quiet system, if I issue an I SMF command, about how long till the switch? I am seeing about 1.5 mins from command to switch.
