Hi Experts,

We have AIX 5.3 TL10 Lpar , one of SAP related file system showing unbelievable DATE's for files. following files and same attached for your reference.
Location: /usr/sap/trans2/tmp
Files: pls see attached image.

More info: SAP team will export this files unders /usr/sap/trans2/tmp files for some perpose, while exporting they found this wired files permission and DATE. Why its showing like 1973 & 1941 and no file permission.

Nice to meet you again, sivaji.
It seems that your server simply had a wrong date/time and/or timezone setting during creation of those files.
What does "date" say now?
What happens when you "touch" one of those files?
Also, the umask of the user creating them seems to have been "000".
If you can rule out all of the above, I fear there could be a serious filesystem problem, and you will have to dismount it and run a "fsck -y" against it as soon as possible! Take care to have a valid backup beforehand!

umask 0000 for the files having rwxrwxrwx, umask 777 for the files having ------
OK, this sounds a bit improbable!
If "touch" and possibly "chmod" don't work or even throw errors, actually do the "fsck" immediately!

What happens when you "touch" one of the files in question? Does the file's date change to now?
As for the causes - if it's not a wrong date setting in the past or corrupt filesystem I don't have any idea, sorry!

  1. Log in to HMC as hscroot.
  2. Click "Systems Management".
  3. Click "Servers".
  4. Click on your managed system.
  5. Mark the checkbox at the left.
  6. Click on ">>" at the right.
  7. Choose "Properties"
  8. Click the I/O tab.
  9. See all your I/O adapters.
    1. A partition name under "Owner" means it's assigned.
    2. "Unassigned" under "Owner" means it's free. (Attention - ignore the "I/P Pool ID" column!)
  10. Be happy.
