Hi

My Storage Admin (NetApp) guy, just told me that the problem was actually zoning, so after he actually set up zoning problem, I am now able to view the LUN that he mapped on the system:

dd

DD(1)							      General Commands Manual							     DD(1)

NAME

       dd - disk dumper

SYNOPSIS

       dd [option = value] ...

EXAMPLES

       dd if=/dev/fd0 of=/dev/fd1
			   # Copy disk 0 to disk 1

       dd if=x of=y bs=1w skip=4
			   # Copy x to y, skipping 4 words

       dd if=x of=y count=3
			   # Copy three 512-byte blocks

DESCRIPTION

       This  command  is  intended  for  copying  partial  files.  The block size, skip count, and number of blocks to copy can be specified.  The
       options are:

	 if = file    - Input file (default is stdin)
	 of = file    - Output file (default is standard output)
	 ibs = n      - Input block size (default 512 bytes)
	 obs = n      - Output block size (default is 512 bytes)
	 bs = n       - Block size; sets ibs and obs (default is 512 bytes)
	 skip = n     - Skip n input blocks before reading
	 seek = n     - Skip n output blocks before writing
	 count = n    - Copy only n input blocks
	 conv = lcase - Convert upper case letters to lower case
	 conv = ucase - Convert lower case letters to upper case
	 conv = swab  - Swap every pair of bytes
	 conv = noerror- Ignore errors and just keep going
	 conv = silent- Suppress statistics (Minix specific flag)

       Where sizes are expected, they are in bytes.  However, the letters w, b, or k may be appended to the number to indicate	words  (2  bytes),
       blocks  (512 bytes), or K (1024 bytes), respectively.  When dd is finished, it reports the number of full and partial blocks read and writ-
       ten.
