We installed WAS61 BASE mistakenly instead of WAS61 ND and one of our administrator delete WAS61 BASE using rm -rf command instead of uninstall. Now the problem is that their is a folder in /opt called WebSphere61 that we are not able to delete and we tried to install BASE product again, but It won't give the permissions to install BASE as well as ND. The OS is Solaris 9. Wait for your early response. Thanks.
