Hi @Vishnumurthy,
It seems that you data disk, RAID5 has failed and inaccessible. If you do not have data backup, I suggest you to seek advice from the nearest data recover center vendor to retrieve the data.
Is OS accessible? The best route now, is to replace the failed disk in RAID 1, to rebuild the VD. Once the rebuild is done, comes the tricky and risky step. For RAID 5 to rebuild, you will need to force online the last failed disk. You probably need to go through server logs in iDRAC to check what is the last failed disk. You should be able to force online the disk via RAID controller management in Lifecycle Controller F10. Then you can replace the first failed disk for the VD to rebuild. Risky part is while rebuilding, the forced online disk can fail and result to a failed rebuild that can cause VD puncture. This may cause more damage to your data.
