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,^_^!

vximportdg(1M)															    vximportdg(1M)

NAME
vximportdg - import a disk group into the Veritas Volume Manager configuration SYNOPSIS
vximportdg daname new_dgname DESCRIPTION
The vximportdg utility performs a temporary import of the disk group contained on the disk device specified by daname to the disk group specified by new_dgname. As the persistent disk group information is not changed within the private partition of the affected disk, the import is only valid for the duration of the bootload or until a vxdg deport is performed. ARGUMENTS
daname Specifies the device name (disk access name) of one of the member disks of the disk group to be imported. The other members are imported automatically. new_dgname Specifies the disk group to be imported. USAGE
One reason to use the vximportdg utility is to import a second generation of the rootdg disk group so that its objects are available for use while a system is running on a different rootdg. To prevent volumes on the second generation rootdg from having the same device minor numbers as volumes (such as rootvol) on the active rootdg, the importation assigns temporary non-conflicting device minor numbers. If this occurs, vximportdg outputs warning messages detailing the mapping of the minor numbers. SEE ALSO
