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?

Re: no DLPAring possible2012-02-08T13:03:33ZThis is the accepted answer. This is the accepted answer.there used to be an excellent dlpar checklist on dw which has gone now..
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

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....
Re: no DLPAring possible2012-02-08T16:44:59ZThis is the accepted answer. This is the accepted answer.I had the same problem couple weeks ago... A new restriction introduced with v7r7.4, you cannot have 2 partitions (1 off and 1 active)with the same IP address managed by a HMC.

- 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.ServiceRM rsct_rm 422096 active
IBM.CSMAgentRM rsct_rm 327864 active
IBM.DRM rsct_rm 286890 active
IBM.SensorRM rsct_rm 426212 active
IBM.ConfigRM rsct_rm 323612 active
ctcas rsct inoperative
IBM.AuditRM rsct_rm inoperative
IBM.LPRM rsct_rm inoperative
IBM.ERRM rsct_rm inoperative
IBM.HostRM rsct_rm inoperative
IBM.MgmtDomainRM rsct_rm inoperative
IBM.FSRM rsct_rm inoperative
IBM.WLMRM rsct_rm inoperative
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 possible2012-11-16T09:34:13ZThis is the accepted answer. This is the accepted answer.Hi 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?
