* it must support locking via flock()

*

* it must be mounted only by one (active) cmu mgt node at a time

*

* it must be NFS exportable (for kickstart/diskless/backup/cloning)

*

*

*

* 2] (at least) one alias IP address:

*

*

*

* this is the address used by the compute nodes to contact the mgt

*

* service, set CMU_CLUSTER_IP into /opt/cmu/etc/cmuserver.conf

*

* this address should follow the active cmu management machine

*

*

*

* [ optionally: a site alias IP address ]

*

*

*

* 3] a third-party HA software:

*

*

*

* this software is responsible for:

*

*

*

* - mounting/unmounting the /opt/cmu-store filesystem

*

* - activating/removing the alias IP address(es)

*

*- using /etc/init.d/cmu startstopstatus ( NOT /opt/cmu/cmuserver)*

setting cmu in audit mode

***CMU is currently in 'audit' mode on cmuadmin1

***use: '/etc/init.d/cmu unset_audit' to unset audit mode

cmu_ha: saving local cmu config in:/opt/cmu-store/etc/savedConfig/cmuconf0-XXXX.sav

cmu_ha: nothing to backup from the cmu HA share merging cmuserver.conf files

`reconf.sh' -> `/opt/cmu-store/etc/reconf.sh'

/opt/cmu/tmp/GUI/config.txt was rewritten

cmu_ha: all existing cmu data has been saved

cmu_ha: if required, restore it with:

/opt/cmu/tools/restoreConfig -f /opt/cmu/etc/savedConfig/<your_cmuconf>

***successfully configured CMU for HA operation

***install CMU similarly on the other management node(s) of the cluster

management node(s) configured so far: cmuadmin1

5.Start cmuserver:

# /etc/init.d/cmuserver start

Because HP Insight CMU is still in audit mode, it is not started but it will detect possible configuration errors. For example:

cmuadmin1# /etc/init.d/cmu start

cmu:core(highavailability) configured (audit mode)

***error : /usr/java/jre1.6.0_31/bin not found

***adjust CMU_JAVA_BIN into /opt/cmu/etc/cmuserver.conf
