Q: RS/6000 'forget' the date after reboot???

Post by leo.. » Thu, 21 Nov 1996 04:00:00



Hi all,

We're running AIX 3.2.5 on C20 more then a year.
Few days ago there was electricity failure and
C20 crashed, hdisk0 (rootvg) crashed and we
change it.

The problem is after crash when machine rebooted
system change date and time and set it to 1 Jan 1970 !!!
Nothing helps. Hardware support provider claims this's
opetration system trouble and not hardware.

I was wondering may it just a battery like in PCs???

Any responces will be appretiated.
Thank you all for waisting your time on this staff.

Leon

Yes, there is a battery, and it should keep date and time. I haven't seen
this happen since AIX 3.2.0.

If the sysplanar is changed or upgraded this problem always occurs.  We
had on of the CPU cards fail in our R30 and after it came back up the
system clock was all zeroes (beginning of epoch - 00:00:00 on Jan 1
1970).  The same thing after the 601 - 604 chipset upgrade.  So, the
system didn't actually "change" the dat/time but read the
clock/calendar which had been reset to all zeroes, possibly from the
system crash or from a CE doing something weird.
