How to avoid seeing various paths to just one LUN?
Hi

I have a server running solaris 10 in which the NetAppadmin has just presented one LUN of 200Gb, but when running:
Code:
bash-3.2# format
Searching for disks...done

c3t500A09828DE3E799d1: configured with capacity of 199.94GB
c3t500A09829DE3E799d1: configured with capacity of 199.94GB


AVAILABLE DISK SELECTIONS:
       0. c0t0d0 <LSILOGIC-LogicalVolume-3000 cyl 65533 alt 2 hd 32 sec 279>
          /pci@400/pci@0/pci@1/scsi@0/sd@0,0
       1. c0t1d0 <LSILOGIC-LogicalVolume-3000 cyl 65533 alt 2 hd 32 sec 279>
          /pci@400/pci@0/pci@1/scsi@0/sd@1,0
       2. c3t500A09828DE3E799d1 <NETAPP-LUN-8030 cyl 6398 alt 2 hd 16 sec 4096>
          /pci@500/pci@0/pci@9/SUNW,emlxs@0/fp@0,0/ssd@w500a09828de3e799,1
       3. c3t500A09829DE3E799d1 <NETAPP-LUN-8030 cyl 6398 alt 2 hd 16 sec 4096>
          /pci@500/pci@0/pci@9/SUNW,emlxs@0/fp@0,0/ssd@w500a09829de3e799,1
Specify disk (enter its number): ^D
bash-3.2#

I see more than one path to the same LUN. How can I avoid this?

NAME

       install-solaris - install the Solaris operating system

SYNOPSIS

       install-solaris

       install-solaris	invokes  the  Solaris  Install	program. Depending on graphical capability and available memory at the time of invocation,
       install-solaris invokes either a text-based installer or a graphical installer.

       The following minimum requirements for physical memory dictate which features are available during installation:

       For SPARC machines:

       128 MB

	   Minimum physical memory for all installation types

       128 MB

	   Minimum physical memory required for windowing system

       384 MB

	   Minimum physical memory required for graphical-based installation

       For x86 machines:

       256 MB

	   Minimum physical memory for all installation types

       256 MB

	   Minimum physical memory required for windowing system

       512 MB

	   Minimum physical memory required for graphical-based installation

       In some cases, even if the minimum physical memory is present, available virtual memory after system startup can limit the number  of  fea-
       tures available.

       install-solaris	exists	only  on  the Solaris installation media (CD or DVD) and should be invoked only from there. Refer to the  for more
       details.

       install-solaris allows installation of the operating system onto any standalone system. install-solaris loads the software available on the
       installation media. Refer to the  for disk space requirements.
