Recently one of my AIX 5.3 systems started failing to boot with the following messages:
fsck: Performing read-only processing does not produce dependable results. + mount /tmp mount: /dev/hd3 on /tmp: Device busy + [ 1 -ne 0 ] + loopled 0x518 /TMP MNT FAILED
The problem turned out to be that /etc/inittab was corrupted. This, of course, has nothing to do with the error message. In my case, the contents of the file had been duplicated into itself.
