Most likely the /tmp filesystem has become corrupted

try an fsck on /tmp (it won't do anything while it is mounted and results may be inconsistent, but it's worth a try to narrow things down a bit):

[tt]fsck /tmp[/tt]

Also, it's a bit strange that you have /dev/hd00 as /tmp, on most installs that FS is on /dev/hd3 ...

Please report back with fsck result?



HTH,

I did fsck on /tmp and

Filesystem Helper: Device open failed.

Thanks

It appears that you will have to boot to maintenance mode using an AIX CD (must be same version) or sysback or mksysb media. Do not mount the file systems at boot, but rather only import rootvg. If you not familiar with this procedure, search the IBM support site for detailed instruction as to how to do this.

Once you have done this you can run fsck on all system filesystems like: / /usr /var /tmp /home. If /tmp is damaged there is a good change one or more of the others are as well.

This should resolve the problem if it is not hardware related, and allow you to reboot normally thereafter.

First step
Are the permissions of /tmp are correct?
The permissions should be rwxrwxrwt

Also it is better to check whether you have any stale PPs in the rootvg
lsvg rootvg |grep STALE
