glance is showing disk util 100% on of production domain and while collecting sar data using sar -d 5 5, avserv for some of the disks are more than 10 miliseconds. Need your advise on steps that needs to be taken to reduce the disk utilitzation.

Is that the "Current", "Average" or "High" figure in Glance? How long were you running Glance for?
Looking at the disc system for 25 seconds isn't going to mean a lot. Try running sar for 30 mins if you are looking for a hot disc.
As mentioned on your CPU thread, the disc figures are meaningless without knowing about your disc configuration, partition placement, mirroring etc., and more about your software.
Thanks for the reply,will observe disk util for the 30 mins and will post the result.
glance showing average value of disk util as 98% and current in 100%.
I am simply using glance command.(without any options)
Considering my limited knowledge at sys admin level,if possbile request you to provide me commands/resources so that I can provide the required details like disc configuration, partition placement, mirroring etc.
Thanks Again...

Im using solaris 8 on a Sunfire 280r. Is there a command to show you how much disk space is being used in gigabytes or megabytes. I dont think theres an option for this using the df command. not for solaris anyway.
