I need to run symstat for perf data on a list of 8 devices for a couple of nights during backup run. Can I specifiy the 8 devices with symstat? will this work  :     #symstat -i 60 -c 5 sid xxx -dev 03D1 03E9 0401 0419 A9 04F1             (or do I need comma? or is it better just run #symstat -i 60 -c 5 sid xxx   (and then yank the other devices info later with vi?)
