Pinned topic no DLPAring possible

‏2012-02-08T11:04:05Z |
HMC and LPARs can communitate in both directions on 657 udp/tcp but DLPARing is not possible (HMC says thet RMC doesn;t work).

on LPARs:
lsrsrc IBM.MCP --- doesn't reurn HMC info

on HMC:
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....

HMC version:
"version= Version: 7
Release: 7.4.0
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)
","base_version=V7R7.4.0
Example P7 server version:
LPAR: AIX 6.1 TL7
VIOS: 2.2.1.0
Firmware: AL730_049
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?
best regards,
oo

    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

      this 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....

    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.

      In my case, it was just some partitions... not all, maybe it's not the same problem

        I have the same problem, anyone knows a solution? Should I downgrade HMC to V7R7.3?

          1. 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 !

    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?

      we have some problem. AIX 7.1 and NAT LPAR do not work :/
