how to figure the internal disks

[amit mehta_2]

To find the internal disks,i do
# ioscan -funC disk
which shows
Class I H/W Path Driver S/W State H/W Type Description
======================================================================
disk 2 0/0/1/0.0.0 sdisk CLAIMED DEVICE SEAGATE ST39204LC
/dev/dsk/c0t0d0 /dev/rdsk/c0t0d0

disk 1 0/0/2/1.15.0 sdisk CLAIMED DEVICE MAXTOR ATLAS15K_36SCA
/dev/dsk/c3t15d0 /dev/rdsk/c3t15d0
=========================
i know that internal disks have smaller H/w Path,but here each one is having similar path size.so is threr any other way?

thanks

Hi Amit,

I would go to the server room, enter the following
dd if=/dev/dsk/cxtydz of=/dev/null
in console, and look at what disk led is continously on.

You have to read the systems documentation to be sure.
The size of the path doesn't matter in this case.


I would bet this is a rp24x0, right?

In this case, the internal drives are

disk 0 0/0/1/1.15.0 sdisk CLAIMED DEVICE MAXTOR ATLAS15K_36SCA
/dev/dsk/c1t15d0 /dev/rdsk/c1t15d0
disk 1 0/0/2/1.15.0 sdisk CLAIMED DEVICE MAXTOR ATLAS15K_36SCA
/dev/dsk/c3t15d0 /dev/rdsk/c3t15d0

thanks to both of you,
as of now i don't have access to the server chamber but will try to do the same once i get the access and what does this rp24x0 means?

thanks.

Hi Amit,

what does this rp24x0 means?

rp24x0 - > It is a model of a PA server.

Please logon to your server and run

model

this will give you the model name of your server.

If you get something like

9000/800/A500-7X

(note the "A500" or "A400") your system is an A-Class server, aka as rp2450 or rp2470.

If you could post the model command output then we could confirm the disks which are internal.

Or you could refer the system block diagram and lookfor the I/O paths.
