Question about the hareware path and device name
# ioscan -f | grep disk
Class I H/W Path Driver S/W State H/W Type Description
disk 3 0/0/2/0.0.0.0 sdisk CLAIMED DEVICE TEAC DV-28E-N
disk 1 0/1/1/0.0.0 sdisk CLAIMED DEVICE HP 146 GST3146707LC c2t0d0
disk 0 0/1/1/0.1.0 sdisk CLAIMED DEVICE HP 146 GST3146707LC c2t1d0
disk 2 0/1/1/1.2.0 sdisk CLAIMED DEVICE HP 146 GST3146707LC c3t2d0
From the document, it says that :
In the hareware path, like 0/1/1/0.1.0, the second zero from left represents the address of SCSI adapte.
In the device name, like c2t0d0, the digit number after 'c' represents the adapter that the disk connects to.
Why are they different for a disk?
Another question is that, there are three disk in my hpux machine, in the directory, there are four files
# ls /dev/dsk
c0t0d0 c2t0d0 c2t1d0 c3t2d0
what does the c0t0d0 represent for ?
Thanks,^_^!

gnome-disks

GNOME-DISKS(1)							gnome-disk-utility						    GNOME-DISKS(1)

NAME

       gnome-disks - the GNOME Disks application

SYNOPSIS

       gnome-disks [OPTIONS]

DESCRIPTION

       gnome-disks is the command to launch the GNOME Disks application. Disks provides a way to inspect, format, partition and configure disks
       and block devices.

       The Disks application is single-instance. What this means is that if the application is not already running when the gnome-disks command is
       invoked, it will get launched and the command invocation will block until the application exits. Otherwise the existing application
       instance will be used and the gnome-disks command will exit immediately.

OPTIONS

       The following options are understood:

       --block-device DEVICE
	   Switches to the Disks application and selects the block device given by DEVICE (for example, /dev/sda).

       --block-device DEVICE --format-device [--xid WINDOW-ID]
	   Shows the "Format Volume" dialog for the block device given by DEVICE (for example, /dev/sdb1). If WINDOW-ID is given, makes the dialog
	   transient to the given XID.

       --help
	   Prints a short help text and exits.
