file size info

Hello.
I can't figure out how to see file size info here.
Can someone comment on this ?

bash-3.2$ uname -a
HP-UX fms-a B.11.31 U ia64 1717699127 unlimited-user license
bash-3.2$ pwd
/u01/app/oracle/oradata/fms
bash-3.2$ ls -l fms_tools_1.dbf
lrwxr-xr-x   1 root       sys             21 Dec 28 01:59 fms_tools_1.dbf -> /dev/rdisk/disk115_p2
bash-3.2$ cd /dev/rdisk/
bash-3.2$ pwd
/dev/rdisk
bash-3.2$ ls -l disk115_p2
crw-r-----   1 oracle     dba         23 0x0000d6 May  4 09:49 disk115_p2

The highlighted text is the size of the file.
