Solaris

At my own eys I can see 4 disks inside of server. Previous admin told me that hardware mirror is done.

What I see with "format" is 2 disks - I suspect that these are 2 MIRRORS.
I just cant be sure because raidctl show this:

Code:

# raidctl -l c0t0d0
Volume                  Size    Stripe  Status   Cache  RAID
        Sub                     Size                    Level
                Disk
----------------------------------------------------------------
c0t0d0                  136.6G  N/A     OPTIMAL  N/A    RAID1
                0.3.0   136.6G          GOOD
                0.2.0   136.6G          GOOD


# raidctl -l c0t2d0
Volume                  Size    Stripe  Status   Cache  RAID
        Sub                     Size                    Level
                Disk
----------------------------------------------------------------
c0t2d0                  136.6G  N/A     OPTIMAL  N/A    RAID1
                0.3.0   136.6G          GOOD
                0.2.0   136.6G          GOOD

Im not sure how to read above. Correct me please, but what I understand is:

Volume c0t0d0 - is 1st MIRROR that contain 2 phisical disks and format display it as
Code:

0. c0t0d0 <LSILOGIC-LogicalVolume-3000 cyl 65533 alt 2 hd 16 sec 273>

Volume c0t2d0 - is 2nd MIRROR that contain another 2 phisical disks and format display it as
Code:

1. c0t2d0 <LSILOGIC-LogicalVolume-3000 cyl 65533 alt 2 hd 16 sec 273>

So phisically 4 disks are used... am I right ?

BUT...

If Volume c0t0d0 is 1st MIRROR and it contain 2 phisical disks 0.3.0 and 0.2.0
then why the heck Volume c0t2d0 which is 2nd MIRROR contain exactelly this same disks ???

Im confused
