Falla en la desinstalacion de Access Control

Si al intentar desisntalar el access control, nos tira un error del tipo:

[root@app4 lbin]# /opt/CA/eTrustAccessControl/lbin/Uninstall

ERROR: Another CA ControlMinder process is currently running.
Wait until the process completes and run uninstallation again,
or remove /tmp/pre_install.
[root@app4 lbin]#

La solucion es borrar el /tmp/pre-install

Upgrade version de SO desde el satellite

subscription-manager register --org="miOrga" --activationkey="ak_miOrga"
subscription-manager release --set=6.9
subscription-manager release --show
yum --releasever=6.9 update

Agregar VIP al cluster 6.6

Editar el archivo /etc/cluster/cluster.conf y agregar la ip como servicio y como recurso

[root@cluster01]# vim cluster.conf

<resources>
      <ip address="10.5.254.3" monitor_link="1"/>
</resources>

<service autostart="1" domain="fd-mbdvdes" name="svc-mbd" recovery="relocate">
              <ip ref="10.5.254.3"/>
</service>

Verificar la version actual del archivo de configuracion del cluster, con el siguiente comando

[root@cluster01]# cman_tool version
6.2.0 config 24
[root@cluster01]#

Ahora con ese dato, editar el archivo de configuracion del cluster ( en ambos nodos del cluster ) y en la primera linea modificarle al version ( sumaremos 1 a la actual, en este caso sera 25 )

[root@cluster01]# vim cluster.conf
<?xml version="1.0"?>
<cluster config_version="25" name="cl-cluster">

Ahora si, replicar la configuracion con el siguiente comando ( ejecutarlo solo en uno de los nodos ) :

cman_tool version -r -S

Ahora chequeo si levanto la ip VIP del cluster

[root@cluster01]# ip ad sh |grep glo |grep bond0

    inet 10.5.252.2/22 brd 10.5.255.255 scope global bond0.150
    inet 10.5.254.3/22 scope global secondary bond0.150
