Understanding an iostat entry

Hi all,
I'm working on a solaris server.
there are no any hardware issue.
but I get the following isostat output:

Code:

# iostat -en
  ---- errors --- 
  s/w h/w trn tot device
    0   0   0   0 c0t5000CCA012AB0081d0
    0   0   0   0 c0t5000CCA012B4CC61d0
    0   0   0   0 c0t5000CCA012A4AA61d0
    0   0   0   0 c0t5000CCA012AAACF5d0
    0   0   0   0 c0t5000CCA012A4E489d0
    0   0   0   0 c0t5000CCA012AD3E69d0
    0   0   0   0 c0t5000CCA012B4B5C9d0
    0   0   0   0 c0t5000CCA012A81FADd0
    0  12   0  12 c1t0d0
    0  12   0  12 c5t0d0
    0   1   0   1 rmt/0
    0   0   0   0 Sdp031:vold(pid679)

I though that I had 2 faulty devices, but in iostat -En, these devices are Virtual.

Code:

Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0

I dont't understand these entries and need to know if it is possible to remove these entries from iostat.

Thx

install-solaris(1M)													       install-solaris(1M)

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.

       Refer to the  for more information on the various menus and selections.
