reset of cache battery time on HSG80

Hello all,

Does anyone know what the command(s) are to reset the time to expiry of the cache batteries on a HSG80 controller is?

Thanks all

RUN FRUTIL

This is used to replace anything/everything on/in the HSG80.

I believe that the first question it asks you is if you replaced the battery during downtime. If you reply yes to this, it will reset the time.

Or. Shutdown/reboot the controllers and then run FRUTIL.

Oh yea... If you actually replace the expired batteries, FRUTIL sets the new experation date for you when you are finished.

By the way - don't reset the time without replacing the batteries. It's tempting - but I wouldn't do it. These batteries expire for good reason - they can only handle so many charge/discharge cycles - and the expiration feature helps you manage this...

I agree completely Chris

If I may add, if you are getting performance problems due to write-caching and flat battery issues (if you have one) you might want to carefully consider SET THIS UPS= i.e. tell it you do have a decent UPS and not to fiddle with the write cache. Like I said carefully consider the implications. The controllers do complain they need a restart on the cli but they won't do it automatically.
