/usr not sufficient during installtion

Hi everyone..

During Installation of solaris 10(in vmware) on X86,,,i gave /usr only 1gb thinking that to install only few packages..But later after inserting the 2nd cd ,,it installed complete 2nd cd,,and gave a status message as "failed".I skipped the installation of later cd's..

I rebooted the system..

Then it didnt load the service descriptions ,,it stopped at :1/1,,then for every second it is giving the message as

alloc:/usr/:file system full

As i am getting the cmd prompt after logging as root..from that i changed the /usr size as 4gb using the format command..but the system is not recognizing this,,and i am getting this message still,,,,Is there any command to reallocate the partitions and make the system to recognize them..

i am getting desktop session but it is being blurred and the keyboard is not working properly at that time..

So any suggestions will be helpful..to get clear my installation errors..

you need 6 gig at least for usr for solaris 10
