X4200 hardware raid not syncing

Question

I got a x4200 with a RAID 1 configuration. Had a bad disk. Saw this in /var/adm/messages:
Mar 22 17:37:00 vps3      Physical disk (target 1) is |missing|
Mar 22 17:37:00 vps3      Physical disk (target 1) is |out of sync||missing|
raidctl -S too showed a failed disk:
c0t0d0               67.9G     N/A     DEGRADED OFF     RAID1
          0.0.0     67.9G          GOOD     
          N/A     67.9G          FAILED     
So, I took it out and then replaced it with a new disk. This is what is being shown in the logs:
Mar 23 20:25:22 vps3      Physical disk (target 1) is |out of sync||online|
However, instead of showing a SYNC status, why does it just say DEGRADED but both disk are good:
root@vps3:/# /usr/sbin/raidctl -l c0t0d0
Volume               Size     Stripe     Status     Cache     RAID
     Sub               Size               Level
          Disk                         
c0t0d0               67.9G     N/A     DEGRADED OFF     RAID1
          0.0.0     67.9G          GOOD     
          0.1.0     67.9G          GOOD     
I am wondering if this command is just lieing to me? How can I ensure the RAID is working properly at this point? What is the best way to delete 0.1.0 device and replace it again?
Thanks

Hardware RAID is configured in one of the new T3-1B blade server from ok prompt and I am able to see the details using show-volumes from ok prompt. But from Solaris OS it is not visible using raidctl -l command. It doesn't return anything. Is there any way to check the RAID status from OS. Making the OS down is not an option everytime.

Edited by: midhu on Jan 26, 2013 5:30 AMYour server seems a little confused as to whether it is a T3 or T4, as you reference T4 in the title and T3 in the body.
raidctl may not be the correct utility because either:-
- (1) A different utility is now needed to configurare the raid for these onboard controllers on newer tin.
or
- (2) You are using an add in raid card that requires different software:
