Method 2 (not recommended)

Change in the state of the Cluster Member	Command in Expert mode	Notes
Change the state of the Cluster Member to DOWN	`cphaconf set_pnote -d <`Name of Critical Device`> -t 0 -s ok register` `cphaconf set_pnote -d <`Name of Critical Device`> -s problem report`	Does not disable Delta Sync.

Notes:

In Load Sharing mode, the cluster distributes the traffic load between the remaining Active members.
In High Availability mode, the cluster fails over to a Standby Cluster Member with the highest priority.
