22 HP SIM quiesce
HP SIM Quiesce is an independent entity which performs the operation of pausing and resuming
the operations of HP SIM. It helps to allow in-progress tasks to complete and block new tasks from
starting, so that a clean backup or export of the CMS management data can be taken.
The task criticality is used during the quiesce operation, which is part of Unattended Backup. When
the system is quiesced, you cannot start any new tasks, or delete or modify existing tasks.
The two main operations of HP SIM Quiesce are:
•
Quiesce
•
Unquiesce
The expected behavior when HP SIM is quiesced is:
•
Lock the system so that the state of the system is not changed, unless the unquiesce operation
is executed.
Locking the system includes:
◦ Not allow any new tasks to be started, any existing tasks to be deleted or modified
◦ Not allow any CLI command that would modify the state of HP SIM to be executed
◦ Not allow any SOAP calls that would modify the state of HP SIM to be executed
•
Any running tasks should either be killed or allowed to complete, depending on the criticality
of the task.
◦ Critical tasks are allowed to complete
◦ Non-critical tasks are cancelled
The expected behavior when HP SIM is unquiesced, is to unlock the system so that you can proceed
with normal operations
Whenever HP SIM is quiesced, you can see the state in the top banner of the HP SIM GUI.
See the HP Systems Insight Manager Command Line Interface guide at for additional information
about setting task criticality using the command line. See the HP SIM online help to see how to set
the criticality using the GUI.
