Problem in /dev/hd1 and /dev/hd9var

Hello AIXians,

I can't boot my AIX, it hangs and stops at the code error: 0518
After searching google, I knew the problem is due to problems in File Systems.
So the solution is booting from any bootable media, then run these commands in maintenance mode:
Code:
#fsck -y /dev/hd4
#fsck -y /dev/hd9var
#fsck -y /dev/hd3
#fsck -y /dev/hd2
#fsck -y /dev/hd1

All of them is done successfully except two, which is:
Code:
#fsck -y /dev/hd9var
#fsck -y /dev/hd1

It gives me this error:
Code:
Fatal: I/O error

What is the solution!?

Waiting our experts or anyone who know the solution, many thanks.

Could be a defect disk. Check your hardware/HMC for error messages or LEDs.
Check out if you have a recent mksysb at hand.

Edit:
Tell us a bit more about your setup, if there is a mirror on the rootvg, if it is physical disks or not, hmc connected, etc. etc.

How many disks do you have in the system. Run diags on the disks. Can you boot in maintenance mode. What disks are these filesystems on?

Thanks dears.
After a long time yesterday and today, we know the reason, which is the processor fan is stopped.
So the system hanging.
