Raidctl - Sun T5240 Solaris 10 Problem

Question

I tried using raidctl earlier today to use my 2 disks in a RAID1 setup and I totally destroyed my OS install. I'm sure I did something funky and it freaked out. No big deal...right?
This is what I was seeing after a reboot.

WARNING: /pci@0/pci@0/pci@2/scsi@0/sd@0,0 (sd0):
Corrupt label - bad geometry
Label says 286718976 blocks; Drive says 286607360 blocks
I decided to just reinstall the OS. It let me go through all of the setup stuff and when it wanted to start installing the OS files I got this message.
Quote:
One or more disks are found, but one of the
following problems exists:
Hardware failure
Unformatted disk.
The server then dropped me to a # command line. I ran format command and saw only one disk showing as a volume, which I believe is what I needed to do for RAID1 setup anyway (create a volume). So I ran format selected the volume and format again to wipe the drive and its been formatting for over 4 hours and all i keep seeing is an incrementing number that started at 0/0/0 but it has taken 4 hours to get from 0/0/0 to 23,000ish/0/0. Is this normal? Have I totally destroyed the disks? Should I be doing something else? I have read a ton of posts and I'm pretty lost at this point. I'm going to let the drive format overnight but I'm scared it will still be doing this in the morning or something crazy.
Any help would be great...

Well I think I got it working now, so I will just post what I had to do for anyone else who needs it.
I came in this morning and the server was still scrolling the numbers like I posted above about my format command. It got to like 47000/12/112 and I decided to just power down the server and take my chances. I've never seen those numbers scroll like that on a Solaris format before. I have no clue what the heck that was, but it obviously wasn't formatting since I let it do it's thing for about 18 hours.
Power cycled and it brought me back to -> prompt (which was odd)
start SYS
start /SP/consoleat ok prompt
boot cdrom -sOnce I got to single user mode I checked to see if my drives still said formatted and they did which was good. I then deleted my raid volume.
raidctl -d c1t0d0It said successfully deleted but when I did a format I was expecting to see both disk show up as they normally would but it still said it was in a raid volume (i have on idea why). I just decided to try and create the raid over again...
raidctl -c -r 1 c1t0d0 c1t1d0It said successfully created and when I went in to format it... it was there as it was before. But this time it let me format>type>0 and it also then me format>label>yes before I deleted the raid it wouldn't let me label the drive saying the VTOC was all messed up.
format>type>0
format>label>yesI forgot to check the raid and make sure it said RAID1 and it was sync'd but I got kind of excited it let me label the volume and just rebooted like an moron. I would def check the raid before continuing to make sure its setup the way you want it.
raidctl -l
raidctl -SI then rebooted and started boot cdrom - nowin
rebootat -> prompt
start /SP/consoleat ok
boot cdrom - nowinI went through the entire disk install and it's now installing the files, so I'm assuming it is now working fine if it doesn't I will post what I see.
