This will make you think so:
Code:
ant:/home/vbe $ vgdisplay vg00
--- Volume groups ---
VG Name                     /dev/vg00
VG Write Access             read/write     
VG Status                   available                 
Max LV                      255    
Cur LV                      14     
Open LV                     14     
Max PV                      16     
Cur PV                      2      
Act PV                      2      
Max PE per PV               4350         
VGDA                        4   
PE Size (Mbytes)            8               
Total PE                    8680    
Alloc PE                    7966    
Free PE                     714     
Total PVG                   0        
Total Spare PVs             0              
Total Spare PVs in use      0

so for confirmation:
choose a lvol: the first one?
Code:
ant:/home/vbe $ lvdisplay /dev/vg00/lvol1
--- Logical volumes ---
LV Name                     /dev/vg00/lvol1
VG Name                     /dev/vg00
LV Permission               read/write   
LV Status                   available/syncd           
Mirror copies               1            
Consistency Recovery        MWC                 
Schedule                    parallel     
LV Size (Mbytes)            304             
Current LE                  38        
Allocated PE                76          
Stripes                     0       
Stripe Size (Kbytes)        0                   
Bad block                   off          
Allocation                  strict/contiguous         
IO Timeout (Seconds)        default

I should add:
To be able to mirror on HP-UX depends on what OS release you have, and so may be an option you have to pay for :
Code:
ran:/home/vbe $ swlist |grep irro
  B2491BA                       B.11.11        MirrorDisk/UX

In other words, if this command doesnt return anything doesnt mean you cannot, e.g if your environment is a mission-critical environment it will be included in the OS

lvremove

LVREMOVE(8)						      System Manager's Manual						       LVREMOVE(8)

NAME

       lvremove - remove a logical volume

SYNOPSIS

       lvremove  [-A|--autobackup  {y|n}]  [-d|--debug] [-h|--help] [-t|--test] [-v|--verbose] [--version] [-f|--force] [--noudevsync] LogicalVol-
       ume{Name|Path} [LogicalVolume{Name|Path}...]

DESCRIPTION

       lvremove removes one or more logical volumes.  Confirmation will be requested before  deactivating  any	active	logical  volume  prior	to
       removal.   Logical  volumes  cannot be deactivated or removed while they are open (e.g. if they contain a mounted filesystem).  Removing an
       origin logical volume will also remove all dependent snapshots.

       If the logical volume is clustered then it must be deactivated on all nodes in the cluster before it can be removed. A single lvchange com-
       mand issued from one node can do this.

OPTIONS

       See lvm(8) for common options.

       -f, --force
	      Remove active logical volumes without confirmation.

       --noudevsync
	      Disable  udev  synchronisation. The process will not wait for notification from udev.  It will continue irrespective of any possible
	      udev processing in the background.  You should only use this if udev is not running or has rules that ignore the devices	LVM2  cre-
	      ates.

EXAMPLES

       Remove the active logical volume lvol1 in volume group vg00 without asking for confirmation:

       lvremove -f vg00/lvol1

       Remove all logical volumes in volume group vg00:

       lvremove vg00
