who and w don't show anything

[ogniemi]

I think it happened after the system migration AIX 4.3 -> AIX 5.2 in the past - we started the problem with "who" and "w" commands - they dont't show users/anything.

# who
# w
07:05AM up 6:51, 0 users, load average: 1.28, 1.00, 0.78
User tty login@ idle JCPU PCPU what
#

Of course "0 users" is not true (I am logged in) and a lot of the other users are logged into the system and using it.

Yesterday we had upgraded system to TL8-CSP but after reboot problem still exists.

thank you in advance for any tip how to investigate and solve the problem.
