cmhaltnode fails on the recovery cluster node where the monitor package (ccmonpkg)
and recovery packages are running
• What is the problem?
When cmhaltnode command is executed on a node belonging to the recovery cluster that
has recovery and monitor packages running, it fails with the following error message on the
console:
Cannot enable package <recovery_package_name> : Disallowed by the
ContinentalClusters product
cmhaltnode: command failed
The following message can also be seen in the /var/adm/cmconcl/logs/checkpkg.log
file :
Cannot determine whether the recovery cmhaltnode fails on the
recoveryup <recovery_group_name> is in maintenance mode. The monitor
package is down.
The monitor package fails over to the other node in the recovery cluster, but the recovery
package does not failover. This error is seen only when a rehearsal package is configured in
a recovery group.
• What is the workaround?
Before executing cmhaltnode command, move the monitor package (ccmonpkg) to another
node in the recovery cluster.
To recover from the above error, ensure that node switching and global switching for the
recovery package are enabled by using cmmodpkg -e command. Manually start the recovery
package on another node at the recovery cluster.
