OK, I could get RDAC to manage the disks without having to deinstall MPIO. I was not aware of command "manage_disk_drivers". This command did the trick that I had been trying for nearly 2 days now.
The issue now is; I could get the DS4k disks migrated to RDAC. But I am not able to identify which class of arrays the following disk belongs to (in bold below).
bash-3.00# lscfg -vl hdisk1
hdisk1 U788C.001.AAA8888-P1-C14-C2-T1-W201C00A0B829EA48-L1000000000000 MPIO Other FC SCSI Disk Drive
Manufacturer................IBM
Machine Type and Model......1818 FAStT
ROS Level and ID............30373330
Serial Number...............
Device Specific.(Z0)........0000053245005032
Device Specific.(Z1)........
Once I figure this out i think i'll be in a much better shape. In the mean time, any help is appreciated.
Thanks!

blk2scsa(7D) Devices blk2scsa(7D)
NAME
blk2scsa - SCSA block device emulation
DESCRIPTION
The blk2scsa module provides support services for generic block devices so that they appear to the system as devices on a virtual SCSI bus,
thus allowing them to be serviced by the sd(7D) SCSI disk driver. The blk2scsa device supports the SCSI-2 command set for Direct Access
Devices. The blk2scsa device supports multiple LUNs per physical device and creates a separate child device for each LUN. All child nodes
attach to sd(7D).
DEVICE SPECIAL FILES
Disk block special file names are located in /dev/dsk. Raw file names are located in /dev/rdsk. See sd(7D).
IOCTLS
See dkio(7I)
ERRORS
See sd(7D).
FILES
Device special files for the storage device are created in the same way as those for a SCSI disk. See sd(7D) for more information.
/dev/dsk/cntndnsn
Block files for disks.
/dev/rdsk/ctndnsn
Raw files for disks.
