Shalom,

This document covers the topic.

I sure as heck would schedule a downtime for this even if it could be done hot.

I would not want my hand in a hot machine running production.

This should be a task to be performed by qualified HP support people!

However, the whole nPar must be down, unless you have online cell replacements supported.

"I would not want my hand in a hot machine running production."

For nPar systems like a superdome this is pretty normal...

Hi,

if you have bad memory in a floating cell, then you can replace it by unassigning it and after memory replacement, reassign it to the partition. Else, you must need to down the npar to replace the memory.

thanks

Actually the procedure in our enviornment is to create the Implementation plan to replace a memory, once the nPar is down, Hp engineer will replace memory and then again we need to bring whole npar & vPar Up

The plan is to shutdown all the vPars and power off the nPar.

Well, I guess you know how to assign points ... you need to open a thread, open the pull down menu next to an answer and select the points. Finally click on "submit points" at the end of the page.

You can do this for all answers in all your threads if you are bored ...

People will also appreciate if you start now to assign points to your current threads ...
