Also when I give format command
It returns
AVAILABLE DISK SELECTIONS:
0. c0t3d0 <SUN1.05 cyl 2036 alt 2 hd 14 sec 72>
When I am mounting other partition like opt slice 7, it is still giving me
following error.
mount:warning:line for "Segmentation Fault.
Can anyone help on this.

-------------------------------------
Kashif,It is difficult to try and diagnose this tye of problem remotely.When
booted from CDROM I would try to verify I have a valid formattedsystem hard
drive installed in the workstaiton. For example:1. Run the "format" command and
verify valid hard disk/target install like "c0t3d0".(Use CNTRL-D to exit
without making changes to the drive)2. If your uncomfortable running the format
command try and verify the disktry using the "prtvtoc" command, for example:#
prtvtoc /dev/rdsk/c0t3d0s0The output should reflect the partitioning as
described in the B0193ND.3. If the format appears correct perform an "fsck" on
"usr" partition.# fsck /dev/rdsk/c0t6d0s64. Have you try mounting one of the
other partitions like root or opt?Root is slice 0, opt slice
