hasys -freeze [-persistent] [-evacuate] system

"-persistent" and "-evacuate" are optional.

Using the -persistent option specifies that the system remains frozen after VCS has been stopped and restarted.

Using the -evacuate option specifies that all groups are switched before the system is frozen; if no other system is available for a service group, it is taken offline.

Hi,

Service Groups need not be evacuated in order to freeze a system. Already active/ONLINE service groups can continue even after freezing the system. Freezing a system prevents service groups from coming online on the system. Thus, no new Service Group can online/switchover/failover on the frozen system.

So, if the maintenance activity of the System is not going to affect already active/ONLINE service groups, you need not evacuate SGs.

Thanks & Regards,
