Administering systems

 To modify a system's attributes

• Type the following command:

  # hasys -modify modify_options

  Some attributes are internal to VCS and cannot be modified. For details on system attributes, see About the -modify option.

 To display the value of a system's node ID as defined in the file
/etc/llttab

• Type the following command:

  # hasys -nodeid node_ID

 To freeze a system (prevent groups from being brought online or switched on the system)

• Type the following command:

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

   

  -persistent	Enables the freeze to be "remembered" when the cluster is rebooted. Note that the cluster configuration must be in read/write mode and must be saved to disk (dumped) to enable the freeze to be remembered.
  -evacuate	Fails over the system's active service groups to another system in the cluster before the freeze is enabled.

 To unfreeze a frozen system (reenable online and switch of service groups)

• Type the following command:

  # hasys -unfreeze [-persistent] system
