2 other LPARs on this box: one weight is 47 the other is 43. We want to make the 3rd LPAR=1 (down from 10) and give the other 9 to the one at 47.
This LPAR shares MIM with one LPAR on this box and 2 other LPARs on 2 other boxes; all are in the same sysplex. So if it IPLs slowly that's where the problems occur?

Have problems occurred? Depends, of course. For starters the weight is relative to the aggregate for the CEC - if that is only, say, 2 (with 2 LPARs weighted at 1 each) you ought not expect to have any problems at all. Probably not your case though. Is your LPAR sharing any resources with any others? GRS or MIM come to mind here... if you need to "run" those on your resource challenged LPAR then you are a troublemaker. If your whimpy LPAR is a monplex, sharing nothing then no, it isn't a problem per se. More of an opportunity to catch up on your reading while you wait for it to respond. (We do it with a sandbox system and it is pretty pokey when the other LPARs are guzzling MIPS. Still, it all works but at an HO-scale. Just not the way to run a real railroad.) -- Tom Schmidt Madison, WI ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
