date clock running too fast

[David_141]

Hi all,

We have one A400/9000 and one A500/9000 both machines are running HP-UX 11.00.

For some reason the clocks are running extremely fast. We run ntpdate and the clock adjusts correctly, then we wait about one second and rerun ntpdate. Ntpdate has to adjust the clock by 10 seconds. We tried running xntp but it can't keep up with the clock running so fast.

Any ideas why the clock is running so fast and how to stop it?

Set someother Server as NTP server and make this server as a client of that. Hope it will try to keep your Server clock under control.

We already tried running ntpd with another machine being the server. It didn't help. NTP can't keep up.

stop ntp on these servers and just watch their clocks. if they are really running that fast with no time corrections begin made, put a service call into to HP, you have a bad clock.

Hi David,

did you configure a drift file in the ntp.conf file. This should help keeping the time, when the server is not able to connect to the NTP server or when you restart NTP.

Another question is, which firmware version are you running on the A-Class servers. The current one is 41.18 I think. You can check the firmware version either in the support tool manager (cstm, xstm) or on the boot prompt.

Firmware is definately out of date then.

Support tool wasn't installed, done now.

Firmware is 40.32.

You can use "date -a" command to slow down your clock speed. But you better call HP to check your machine.

man date for information.

Hope this helps.

Some clocks will vary about a second per day, some vary a few seconds per week.

Yours seems to gain way too much and looks like a visit from HP is required.

We have had this problem. DO you have 440Mhz processors in the boxes? The board for the A-class has a jumper that tells the board if the processor is 440Mhz or 550Mhz. The older boards had the jumper set by default to 440Mhz, but HP is in a new batch of boards, and their jumper is set to 550Mhz. People keep forgetting to move the jumper for the 440Mhz machine.

We had a board go bad and it got replaced. Our CE forgot to check the jumper, so we got the same problem.

Hope it helps.

David,

Have you resoled this issue? The reason I ask is that I to am experiencing the same issue. If this was fixed by changing the jumper settings I would appreciate any details.

Thanks,
Dave
