Thanks for Ur reply
still get the same error
Code:
# growfs -M / /dev/dsk/c2t0d0s0
devinfo: /dev/dsk/c2t0d0s0: Inappropriate ioctl for device
growfs: cannot get partition size

# 4  
"Inappropriate ioctl for device" isn't the same error as "No such file or directory".

1: You need to specify a raw device.
2: You can't grow / anyway. You need to boot from a different media to achieve that.

All, Can we grow a file system even if its not part of any volume?
# 6  
Yes as long as the underlying partition can be grown.

Thanks all..
