probleme

Vous avez une partition dont le partitionnement dynamique ne fonctionne plus. Vous obtenez un message d'erreur au niveau de la console hmc ressemblant à ceci:

Sur la console hmc en mode ssh la commande lspartition -dlpar indique que votre partition n'est pas en mode dynamique (*Dcaps à 0). 

lspartition -dlpar
<#0> Partition:<18204-E8A06A6DA6, batman, 10.172.12.18>      Active:<1>, OS:, DCaps:<0x85f>, CmdCaps:<0xb, 0xb>, PinnedMem:<1603>

procedure

  1. reboot de la HMC et attendre 10 minutes

    Si le problème persiste, connectez vous sur la partition et arrêtez rsct et rsct_tm 

    s#topsrc -g rsct
0513-044 The ctrmc Subsystem was requested to stop.
#stopsrc -g rsct_rm
0513-044 The IBM.ServiceRM Subsystem was requested to stop.
0513-044 The IBM.CSMAgentRM Subsystem was requested to stop.

#lssrc -a |grep rsct
ctcas            rsct                          inoperative
IBM.CSMAgentRM   rsct_rm                       inoperative
IBM.ServiceRM    rsct_rm                       inoperative
IBM.AuditRM      rsct_rm                       inoperative
IBM.ERRM         rsct_rm                       inoperative
ctrmc            rsct                          inoperative

  2. vérifiez que plus aucun démon ne soit actif , faire un kill _6 voire un kill -9 dans le cas contraire.
  3. déconfigurez et reconfigurez rsct

    #/usr/sbin/rsct/install/bin/uncfgct -n             
#/usr/sbin/rsct/install/bin/cfgct                  
0513-071 The ctcas Subsystem has been added.
0513-071 The ctrmc Subsystem has been added.
0513-059 The ctrmc Subsystem has been started. Subsystem PID is 888890.
             
#usr/sbin/rsct/install/bin/recfgct
0513-071 The ctcas Subsystem has been added.
0513-071 The ctrmc Subsystem has been added.
0513-059 The ctrmc Subsystem has been started. Subsystem PID is 770132.
  4. vérifiez la connexion entre le serveur et la hmc

    Pour une seule hmc connecté on aura: 

    lsrsrc IBM.ManagementServer
Resource Persistent Attributes for IBM.ManagementServer
resource 1:
       Name             = "10.172.12.200"
       Hostname         = "10.172.12.200"
       ManagerType      = "HMC"
       LocalHostname    = "10.172.12.16"
       ClusterTM        = "9078-160"
       ClusterSNum      = ""
       ActivePeerDomain = ""
       NodeNameList     = {"wonderwoman"}
    pour deux hmc, il y aura deux ressources 

    #lsrsrc IBM.ManagementServer
Resource Persistent Attributes for IBM.ManagementServer
resource 1:
       Name             = "10.128.1.93"
       Hostname         = "10.128.1.93"
       ManagerType      = "HMC"
       LocalHostname    = "10.172.12.30"
       ClusterTM        = "9078-160"
       ClusterSNum      = ""
       ActivePeerDomain = ""
       NodeNameList     = {"dualboy"}
resource 2:
       Name             = "10.172.12.226"
       Hostname         = "10.172.12.226"
       ManagerType      = "HMC"
       LocalHostname    = "10.172.12.30"
       ClusterTM        = "9078-160"
       ClusterSNum      = ""
       ActivePeerDomain = ""
       NodeNameList     = {"dualboys"}

    Si vous n'obtenez pas ces informations lancez les commandes suivantes : 

    #/usr/sbin/rsct/bin/rmcctrl –z                     
#rm /var/ct/cfg/ct_has.thl                         
#rm /var/ct/cfg/ctrmc.acls                         
#/usr/sbin/rsct/bin/rmcctrl -A
0513-071 The ctrmc Subsystem has been added.
0513-059 The ctrmc Subsystem has been started. Subsystem PID is 663690.                   
#/usr/sbin/rsct/bin/rmcctrl -p
  5. Attendez 10 minutes car il y a des lazy demons et vérifiez l'etat du partitionnement dynamique sur la HMC en lancant en mode SSH : 

    #lspartition -dlpar  
<#0> Partition:<18204-E8A06A6DA6, batman, 10.172.12.18>      Active:<1>, OS:, DCaps:<0x85f>, CmdCaps:<0xb,
       0xb>, PinnedMem:<1603>
<#1> Partition:<48204-E8A65C3882, ironman, 10.172.12.17>      Active:<1>, OS:, DCaps:<0x84f>, CmdCaps:<0xb,
       0xb>, PinnedMem:<1120>
<#2> Partition:<38204-E8A65C3882, wonderwoman, 10.172.12.16>      Active:<1>, OS:, DCaps:<0x84f>, CmdCaps:<0xb, 
      0xb>, PinnedMem:<1206>
<#3> Partition:<38204-E8A06A6DA6, superman, 10.172.12.21>      Active:<1>, OS:, DCaps:<0x85f>, CmdCaps:<0xb, 
      0xb>, PinnedMem:<2809>
<#4> Partition:<28204-E8A06A6DA6, the_thing, 10.172.12.19>      Active:<1> <, OS:<AIX, 5.3, 5300-11-06-1107>, 
< DCaps:0x85f>, CmdCaps:<0x0, 
     0x0>, PinnedMem:<1202>
<#5> Partition:<28204-E8A65C3882, green_arrow, 10.172.12.15>      Active:<1>, OS:, DCaps:<0x84f>, CmdCaps:<0xb, 
      0xb>, PinnedMem:<2015>

    La partition doit etre active et on doit avoir une valeur à 8 pour Dcaps.
