Hi,

Installation of AIX's native mpio results in a bosboot failure. Subsequently a bosboot -Da fails with the same set of errors. Below are the error messages it reported.

0301-158 bosboot: mkboot failed to create bootimage.

0301-165 bosboot: WARNING! bosboot failed - do not attempt to boot device.

Any idea as to what is going wrong here? How do i go about fixing it?

There's something wrong with your kernel file. By default, bosboot copies /unix to a temporary working directory. If /unix is missing, then it looks for /usr/lib/boot/unix. Thos are both supposed to be symlinks to a regular file.

Anyways, the dump and the nm error messages both indicate that file is bogus. You can try to copy the matching version of that file from another machine, or perhaps you can get it from installation media. In any event, it MUST match whatever version of AIX you have installed.

Thanks for the response. There is a symlink between /unix and unix_64. Are you saying that /unix is corrupted?

bash-3.00# ls -l /unix
lrwxrwxrwx 1 root system 21 Mar 13 2009 /unix -> /usr/lib/boot/unix_64

Which file did you want me to copy over to this machine? /unix?

what does ls -l /usr/lib/boot/unix_64 indicate?

Hi there,
I was able to fix those errors by copying over unix_64 from another machine (known good one) to the problematic one. But subsequently the kernel crashed while uninstalling an eFix. :(

Anyways, i have the drive re-imaged now. Thanks for the suggestions.
