Hardware RAID not recognize the new disk [Sun T6320]

We have hardware RAID configured on Sun-Blade-T6320 and one of the disk got failed. Hence we replaced the failed disk. But the hot swapped disk not recognized by RAID. Kindly help on fixing this issue.

We have 2 LDOM configured on this server and this server running on single disk.

Code:
# raidctl -l
Controller: 0
        Volume:c0t0d0
        Volume:c0t2d0
        Disk: 0.1.0

        Disk: 0.4.0

hmm... i would pull the disk out and after 1 minute put it back in to see if it is recognized by the raid controller.
# 5  
we have already tried the possibilities like pulling the disk out and reinserting the same. No luck. We heard something REM version needs to be upgraded. As we have 2 LDOMs running on this single disk server we are worried about the REM upgrade.
# 6  
You need to ensure that the swapped disk has at least the same, if not more, LBA's than the disk its going to mirror. Many times I have seen what appears to be the same model of disk with different LBA's.

If the disk has even one less LBA than the one being mirrored then the controller will refuse to do it (even though the disk can be physically seen by the system).
# 7  
yes i also face this type of problems once a time,,where LBA,s are not the same due to which we have order other disk with same LBA..plz check that part number should be same...
