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.

Re: Npar & Vpar

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.

Hope this helps!

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

Re: Npar & Vpar

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.

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

Re: Npar & Vpar

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 ...

Hope this helps!
Regards
Torsten.
