Now to cleanup I did below, whether any of /uXX existed or no:

umount /u00 /u01 /u02
rmdir /u00 /u01 /u02
Modifiec /etc/vfstab to have below entries:
/dev/dsk/c0d0s3 /dev/rdsk/c0d0s3 /u00 ufs 2 yes -
/dev/dsk/c0d0s4 /dev/rdsk/c0d0s4 /u01 ufs 2 yes -
mkdir /u00 /u01
mount /u00
mount /u01 [This gave an error:]
mount: No such device
mount: Cannot mount /dev/dsk/c0d0s4

Even though I can see one directory exist as /u01

Please suggest.

Do you have

(a) a copy of what your vfstab was before

(b) a copy of what "mount" said before?

can you print out your partition table with format?

I had not copied the entries of vfstab and mount - But I remember the device names and allocated sizes. Here is the output related to /u01 after format command:

/dev/dsk/c0d0s3 is currently mounted on /u00. Please see umount(1M).
/dev/dsk/c0d0s4 is normally mounted on /u01 according to /etc/vfstab. Please remove this entry to use this device.

Output of print table:
Part Tag Flag Cylinders Size Blocks
4 unassigned wm 1355 - 2660 10.00GB (1306/0/0) 20980890 [The one I have problem with]
4 unassigned wm 1355 - 1409 431.43MB (55/0/0) 883575 [This I was trying to create in morning with 55c, But had got an error while using mkfs as the allocated space was unavailable.

Please advice!

I have managed to reboot and repair of filesystem. Let me post the fresh query here again:

I have got 2 FileSystems visible when I use df -k or mount command /u00 and /u02 of 5 GB and 10 GB respectively. Can you please let me know exact commands to execute for below:

1) Delete /u00
2) Modify /u02 from 10 GB size to 5 GB size
3) Create /u01 (new fs) of size 10 GB

Thank you!

You can't really do that without deleting then recreating.

What I was suggesting you do is use what you already have, because the partition/filesystem sizes are what you want, but just on the wrong mountpoints.

I suggest you save a copy of your /etc/vfstab, umount the two, mkdir the mountpoints you want, then change your /etc/vfstab to put the appropriate filesystem on the correct mountpoint, then mount them.

But then How would I assign or allocate the size for new filesystems?
