Operating Systems AIX Problem in /dev/hd1 and /dev/hd9var Post 302869855 by Mohannad on Thursday 31st of October 2013 09:08:53 AM

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.
