oslevel -s reports incorrectly after OS migration from 5.2 to 5.3

After AIX is upgraded from 5.2 to 5.3. The oslevel -s reports incorrectly.

# oslevel -s

5390-00-00-0000

I am looking from 5300-09-02-0849

lppchk -v is clean. The root cause is some filesets are not migrated or deleted during OS migration.


# lslpp -aL|more
then search 5.2, some of the filesets are still in 5.2 level.

use installp -u fileset_name to remove all those filesets.

Now oslevel -s returns correct level.
