boot failure

[tedans]

hi,

We have a RS/6000 43p0-150 that failed to boot due to an error on mounting the /usr maybe because of a corrupted file which probably points to "libc.a" as the error it displayed. Tried to recover it with system boot but failed to access the rootvg.
I have this idea that transfering the hard disk to another RS/6000 so I can access the content of the disk and probably replace only the libc.a and its related files which may have been the cause of boot failure. Afterwhich I'll put it back and try to boot. Will this idea be ok?
The failed RS has no system backup.
Last option will be to replace the OS with the backup of another RS/6000 43p with the same application but we're trying to avoid that since there is a licensed application on the failed disk. Replacing would mean loss of the license.
HELP please

HI,

I suspect that libc.a file is OK,you just get a notification on this library when trying to import rootvg.
Workaround - do not go to tcsh,stay in the shell you boot into.

I think that after importing a rootvg the simle fsck on /usr may help.

I had this libc.a error trying to import rootvg,it's just a boot environment issue.

I have done fsck on /usr through service mode maintenance using the AIX CD. I chose "Accessing root volume group before mounting a shell" .However after doing the fsck including the other filesystems (/,/var/,tmp/,home) and execute "exit" to mount the shell or filesystems and error comes out:

Could not load program:
Dependent module /usr/lib/libc.a(shr.o)could not be loaded
member shr.o is not found in archive

This error is OK - I also get it,some environmental problem.

But if you boot after fsck - does it work ?

can you mount the /usr fils-system manually after fsck? note that "/usr/lib/lic.a is a symbolic link to /usr/ccs/lib/libc.a ; if you can mount, see if the link exists and the file is ok.

no the /usr can't be mounted after the fsck that is why rootvg cant be accessed. Even by manual mounting, only the /usr can't be mounted.
