I'm running Solaris 10 on a Sun V245. A previous admin said HW
mirroring
was setup using raidctl. However, when I look at raidctl and print out
the disk vtoc's, I don't see any vtoc matching each other. Therefore,
I don't think any mirroring is going on.

Is there anything else I should check before to make sure mirroring is
not
enabled ?

Here's what I currently see:

/: raidctl -l
Controller: 1
Disk: 0.0.0
Disk: 0.1.0
Disk: 0.2.0
Disk: 0.3.0
Controller: 2

root(a)cmsfaal1 /: raidctl -l c1t0d0
Device not found.

format
0. c1t0d0 <SUN72G cyl 14087 alt 2 hd 24 sec 424>
/pci(a)1e,600000/pci@0/pci@a/pci@0/pci@8/scsi@1/sd@0,0
1. c1t1d0 <SUN72G cyl 14087 alt 2 hd 24 sec 424>
/pci(a)1e,600000/pci@0/pci@a/pci@0/pci@8/scsi@1/sd@1,0
2. c1t2d0 <SUN72G cyl 14087 alt 2 hd 24 sec 424>
/pci(a)1e,600000/pci@0/pci@a/pci@0/pci@8/scsi@1/sd@2,0
3. c1t3d0 <SUN72G cyl 14087 alt 2 hd 24 sec 424>
/pci(a)1e,600000/pci@0/pci@a/pci@0/pci@8/scsi@1/sd@3,0

I assuming I need to do something like:

raidctl -c c1t0d0 c1t1d0 - mirror first disk to second disk.

Thanks,
Carl

afaik: it is hw raid, so once enabled you can not see the underlaying
disks with format, e.g if you mirror two it results in three disk in format.

The "raidctl -l" command shows no volumes, so you're not mirrored.
Your command to create the RAID volume should work, but I believe it
would be destructive to the file systems on the disks.
