HA Configuration : Managing HA configuration : Halting a storage system
Halting a storage system
You can halt one of the storage systems in an HA configuration without a takeover by the partner system. You might want to halt a storage system when you have to perform maintenance on both the storage systems and their disks and therefore avoid an attempt by the partner node to write to those disks.
Steps 
1.
From the home page, double-click the appropriate storage system.
2.
Click HA Configuration.
3.
From the Halt system menu, select the appropriate partner storage system.
4.
Select the confirmation check box and click Halt.
5.
Verify that the storage system is halted in the HA Configuration window.
