Vertias disk list

OS Version: Solaris 10
Veritas Version: 4.1

Running vxdisk list gives me this:
DEVICE TYPE DISK GROUP STATUS
c0t0d0s2 auto:none - - online invalid
c1t10d0s2 auto:sliced disk01 rootdg online
c1t11d0s2 auto:sliced rootdg01 rootdg online

Running vxdisk list c0t0d0 shows 2 other disks (c0t1d0 and c0t0d1) - what caused them to be 'tied' to c0t0d0? What exactly does it mean?

Device: c0t0d0s2
devicetag: c0t0d0
type: auto
info: format=none
flags: online ready private autoconfig invalid
pubpaths: block=/dev/vx/dmp/c0t0d0s2 char=/dev/vx/rdmp/c0t0d0s2
Multipathing information:
numpaths: 3
c0t0d0s2 state=enabled
c0t0d1s2 state=enabled
c0t1d0s2 state=enabled

Why doesn't vxdisk list show the disks c0t1d0 and c0t0d1 as separate disks?
What other veritas commands may show more info on the configuration? (Note: can't run GUI interface - only command line to get info)

(Trying to figure out HOW this came about - can't make changes to server/disks. Multiple attempts at getting c0t1d0 and c0t0d1 to show up in veritas as their own disk versus being 'tied' to c0t0d0)

Vertias

Admins, I found this site is really helpful for all the Unix Admins also those who required scripting. My suggesstions is if you add some documents, commands and examples/sceanarios of Vertias Volume Manager or Veritas Cluster it will be useful for us. Thanks a lot Sridhar S:)

Command to List Hard Disk Information

I have a SparcStation5 that is making sounds that make me think the disk drive(s) may be on the verge of quiting. What is the command to list the disk types and sizes? I'm thinking I can possibly pick up another drive or two and compy the exisiting drives while they are still working.

NAME

       pfto - Powerfail Timeout

DESCRIPTION

       HP-UX  SCSI disk device drivers have a timeout facility that detects non-responding disks.  VxVM uses this mechanism in its Powerfail Time-
       out (pfto) feature.  You can specify a timeout value for individual VxVM disks using the vxdisk command (see the EXAMPLES  section  below).
       If a disk fails to respond in the specified timeout period, the driver receives a timer interrupt.

       pfto  values  are persistent across reboots, that is, after the pfto value is set, it remains in effect until you explicitly change it.	If
       dynamic multipathing is enabled, the pfto value set on a disk applies to each path of a multipath disk device.

       The pfto value is in seconds. If pfto is not specified, or is zero, the timeout period is 30 seconds.  Both the vxdisk and vxprint commands
       display the current pfto value for a disk.

EXAMPLES

       Use the following command to set the value of pfto to 30 seconds on disk01:

	      vxdisk -g rootdg set disk01 pfto=30

       Use either of the following commands to display the pfto value on the VxVM disk disk01:

	      vxdisk list disk01
	      vxprint -l disk01

EXIT CODES

       Setting the pfto value on a non-VxVM disk returns an error.
