Date Time not working - battery dead?

[piefum]

Hi all

I am setting up a system that uses a Power Brick LV in the IMS format.

Due to some problem in our hardware development, the PMAC stayed on my shelf for about 6 months.

Now I am setting up the system: unfortunately, the Date and Time settings on the linux machine are not kept after a power down.

To set the date and time, I connect via ssh and launch:

mount -o remount,rw / 
date --set 2017-06-26
date -u --set 10:11:23
mount -o remount,ro /

That seems to work up until the power is on. After a power cycle, the date information is lost. Am I missing some commands or should I proceed with the replacement of the battery?

 

Thanks

gigi

This is purely a Linux feature. Power PMAC does not have a real-time clock option. You would need to setup a Linux NTP (Network Time Protocol) server/client package and update time from a “network” source. This is well documented in Linux literature.
