Hi All,
As part of my Y2K testing I intend rolling the date forward on my filer (F230, currently 5.2.1, NFS & CIFS) to just before midnight on the 31st and then watch it as it ticks over midnight. So far, so good. The issue I have (assuming the filer is Y2K compliant!) is rolling it back again.
Has anyone rolled their filer forward and then back again to put it back into production? Were there any glitches? There will be files that will have modified dates in the future, but these can be a copy of some production data which can be deleted after the test.

Hi Garrett,
I haven't rolled a filer forward beyond 31 Dec 1999 and back, but I have installed a filer which had the date set in the future, then set the clock back without problems. The files which had future dates were config files in /etc, and simply showed up with their future dates when that directory was listed.
One thing you obviously will see is entries in /etc/messages which are out of sync with real time from the period of time when the clock is set to the future.
Regards, Matt.

I have done this and then reset it with no problems (I'm not sure why you'd expect any).
(This was with the 5.3 release)

Just an aside (almost certainly way beyond what you require, which I think has already been answered !) -
ONTAP 5.3 has an optional (license required !) "snaprestore" feature. This basically allows you to restore an entire volume back to any chosen snapshot, over a filer reboot. This gives the additional benefit of allowing you to take a snapshot, perform whatever tests you like (eg application changes, full Y2K testing, etc), then to rollback the entire volume within a couple of minutes to exactly how it was at the point of the snapshot.
Just thought I'd mention it !
Cheers Mike

But a reboot DOES take only a couple of minutes, so the benefits are minimal.

You are, of course, also planning to set it to 23:59 on February 28, 2000 and make sure it rolls over to February 29, 2000, right?
(Yes, we should handle that correctly:
tooting.eng.netapp.com$ egrep isleap /rlse/5.2.1/prod/common/lib/tzfile.h #define isleap(y) (((y) % 4) == 0 && (((y) % 100) != 0 || ((y) % 400) == 0))
(thank you, Arthur Olson), and I think that was part of our Y2K testing, but if you're going to check 1999-12-31 -> 2000-01-01, you should probably check 2000-02-28 -> 2000-02-29 on your machines as well.)

And while you're at it 99-9-9 should also be checked just to be sure that someone creative didn't use that as a sentinel as well.
