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             

ant:/home/vbe $

So would the output of vgdisplay -v ...

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

If on linux you'll see devices named md* on df(1) if you have RAID configured.

Oops, didn't see that it was on HP-UX .

maxim42, you have to take a closer look to vbe's output:
Code:
Current LE                  38        
Allocated PE                76

The example Logical Volume he shows has twice as many physical extents that logical which shows that it is mirrored (I guess that's just similar to AIX LP and PP, Logical Partitions and Physical Partitions - just as I sneaked in here Smilie).
