Environment
Primary Site = 2 nodes
DR Site = 1 node
OS = RHEL 5.x
SFHA version = 5.1 SP1
Replication connectivity = on Layer-II
Query
Primary Site is going to move to a new site. This required around 20 hours downtime in moving the hardware from Primary Site to New Site.
While 20 hours application will be run from DR site. While running from DR Site the application data will be at risk as there will be no replication as Primary Site hardware will be offline as to move to a New Site.
My Plan
Before moving the hardware to a New Site. I want to place a node on a New Site and want to configure replication between DR Site and New Site (Dont have a plan to control new replication under cluster control). Through this my data will be secure while 20 hours downtime.
When the hardware will reach to New Site we plugged in and online the old Primary Site both nodes and resume replication.
