EXP400 with 43P machine not booting

Hello

I connected the exp400 & turned on the aix machine which is 7043-150 but now I guess probably ODM is corrupted as it does not boot. Its stuck at 0518 code.

Also, on the console it shows stuck on the kernel, which then it does not want to boot. Is it possible to fix from maintenance mode, if so what are the steps.

I have disconnected the EXP400 form the system now but I was told that it is compatible with the aix machine.

Just to let you know since I just have one scsi cable so I had only one power supply for EXP400 turned on & only 5 hard drives were installed on the same side.

Help would be appreciated

Thanks
