The HA for Solaris Zones components consist all of the resource type SUNW.gds (5) . As described in Stop_command Property in Oracle Solaris Cluster Generic Data Service (GDS) Guide , the value for the Stop_timeout should be chosen so that the Stop_command can successfully return within 80% of its value.
The stop method for the zone boot component spends 60% of the value for the Stop_timeout performing a complete zoneadm -z zonename shutdown command for the zone. If that failed, the next 20% of the value for the Stop_timeout will be spent halting the zone performing a zoneadm —z zonename halt command and perform some additional cleanup steps in order to force the zone into the state installed. Therefore the Stop_timeout value for the zone boot component should be computed so that 60% is enough to successfully shutdown the zone.
The default setting for the Migrationtype variable is cold. For a solaris-kz branded zone, you will be able to set the Migrationtype variable to warm or live.
If Migrationtype is set to warm, the stop method uses the "zoneadm -z zonename suspend" command, instead of the zoneadm -z zonename shutdown command. Or, if Migrationtype is set to live, the stop method uses the zoneadm -z zonename migrate command, instead of the zoneadm -z zonename shutdown command. Therefore, the Stop_timeout value must be tuned properly, when the Migrationtype variable to set to warm or live.
The stop method for the zone script component calls the command or script configured for the ServiceStopCommand keyword. Therefore the Stop_timeout value for the zone script component should be computed so that 80% is enough for the configured ServiceStopCommand to succeed.
The stop method for the zone SMF component spends 60% of the value for the Stop_timeout using svcadm to disable the configured SMF service in the zone. If that failed, the next 20% of the value for the Stop_timeout will be spent to first send SIGTERM then SIGKILL to the processes associated with this SMF service. Therefore the Stop_timeout value for the zone SMF component should be computed so that 60% is enough to successfully disable the configured SMF service in the zone.
