usr are the systems files of solaris....all the files are importants..it seems that all the files are important.....u have to check each file system with du -hk file system name to get usage of disk space for each files and folder

Your /usr partition is huge (32 Gigabytes).
What really matters is whether the free space going down and at what rate.

The first thing to look for is large files. Note the "-xdev" parameter to "find" which keeps you to the current filesystem. We can see many links to other filesysystems in your directory listing.
To look for files larger than 10 megabytes (yes anything much bigger than this in a standard /usr partition would be unusual).
Code:
find /usr/ -xdev -type f -size +10485760c -exec ls -lad {} \;

DO NOT DELETE THE FILES. Just look and decide carefully what to do.
Feel free to post sample listings for an opinion.
What I expect you will post will be huge log files or something like that.
