HMC and LPARs can communitate in both directions on 657 udp/tcp but DLPARing is not possible (HMC says thet RMC doesn;t work).
lsrsrc IBM.MCP --- doesn't reurn HMC info
lspartition -dlpar ---- return nothig.
"hmcshutdown -r -t now" -- doesn't solve the problem.
Also LPAR restart doesn't fix problem. RMC subsystems are running, telnet o port 657 works.
there are different types of servers (P6 and P7) managed by that HMC but noone in DLPARable....
"version= Version: 7
Service Pack: 0
HMC Build level 20111010.1
MH01275: Required fix for HMC V7R7.4.0 (10-10-2011)
MH01296: Fix for HMC V7R7.4.0 (11-07-2011)
Example P7 server version:
LPAR: AIX 6.1 TL7
so supported according to http://www-933.ibm.com/support/fixcentral/firmware/supportedCombinations
Firewall on HMC has enabled 657 tcp/udp port
any idea what else can be checked?

but this one might be as helpful, (should be in an faq...) : http://www-01.ibm.com/support/docview.wss?rs=111&context=SWG10&q1=dcaps&uid=isg3T1010615&loc=en_US&cs=utf-8&lang=en

Re: no DLPAring possible2012-02-08T15:32:31Z in response to j.gannthis is exactly the url which I have tested before I decided to wrote here on forum....
alas i didn;t find any solution there.... it only says that for my case IBM support can only help...
if yes, thany it would mean that newest HMC version has a bug....

- What are common reasons for failures with Dynamic Logical partitioning ?
Maximum time cause will be the broken RMC connection between HMC and LPARs.
a) Login to HMC cli.
b) lspartition -dlpar
if you can't see any o/p then there is an RMC problem.
c) close all Serviceable Events and reboot the HMC.
d) hmcshutdown -r -t now
After HMC reboot wait go for a coffee :)
e) lspartition -dlpar
if still no o/p then log a call with IBM.
Assume DLPAR is working for other LPARs on this HMC :
a) login to the LPAR
b) su - root
c) lssrc -a |grep rsct
root# lssrc -a|grep rsct
ctrmc rsct 291002 active

IBM.DRM is the most important daemon for DLPAR !
You can try stop and starting RMC as below ,
d) /usr/sbin/rsct/bin/rmcctrl -Z
e) /usr/sbin/rsct/bin/rmcctrl -A
f) /usr/sbin/rsct/bin/rmcctrl -P
now try with below command again if you luckly.
g) lssrc -a|grep rsct
check for IBM.DRM if yes then this is resolved !
go to HMC cli again
h) lspartition -dlpar
if you can see the O/P then it's resolved
Hope this will have you guys !
Re: no DLPAring possible2012-11-16T09:34:13Z in response to ogniemiHi Ken,
have you solved your problem?
I have a similar problem. I have a IP NAT between HMC and some LPAR.
In old p5 worked well but in new p7 (and AIX6.1 LPAR) this communication does not work.
Do you have a NAT? If yes, how did you solve it?
