If one node has a date of 1970 (fail over) and my production node is current, will this cause a problem when I try to start HACMP on my fail over node? HA is running on my production box.
 
tristan,

I have never tried this but I anticipate that it may cause you problems, you will at least get some errors about the date but it may actually fail over successfully, you will have to try it. IBM recommend that you sync. the clocks in any HACMP cluster via setclock, timed, xntpd e.t.c.

The other question is why is the date 1970???

I have no idea why the date went to 1970. We had IBM add a process and some disk (which lasted 2 weeks) then upon bringing the Fail Over box back up it decided to try and take over our production system and brought it down. Happen to check the date after shutting him down and it said 1970??? Who knows. So how exactly to do I go about sync. the time?
 
tristan,

Well the easiest way is to just use setclock - i.e.

On nodea:

setclock nodeb

The add this to the cron to run every night at say 3:00 am or whenever this is convenient.

There were also a few problems in 4.1.5 I had that set the date back to 1970 after certain patch updates, are you on 4.3.3?

Cheers
