Thanks to all those who replied regarding getting stats for disk usage at partition (file-system) level rather than disk level. Unfortunately the consensus is that this is not available until solaris 2.6 and i cannot yet upgrade. Prompted by Birger Wathne i found a fuller discussion of this and other performance related enhancements of 2.6 at

My original question was :

i manage a ss2000 running solaris 2.5 and with scsi-connected disks under the control of online disk-suite 4.0. i am using sar to monitor disk usage and it indicates heavy use on a number of disks. because the configuration is striped and mirrored it is difficult to pin-point which file-system is taking the hit. what i need is a utility which will report the areas of the disk being most heavily used, preferrably indicating which file-system resides there. i have used a utility called sadp before on ICL Unix machines which does the job, albeit clumsily. thanks in advance and i will summarise
