I get a result something like this:
Linux 2.6.18-238.el5 (mon01) 09/03/2011 Device: tps Blk_read/s Blk_wrtn/s Blk_read Blk_wrtn sda 9.83 11.88 264.67 38378414 854835288 sda1 9.83 11.88 264.67 38375658 854834320 sda2 0.00 0.00 0.00 2346 968 sdb 58.40 7.96 1552.02 25716671 5012803778 sdb1 58.40 7.96 1552.02 25715861 5012803778

iostat -d 1 5
...rather than the last time I ran
I am slightly confused here.
