In a TS7740 two-way grid Cluster 0 is the production site and Cluster I is the remote DR site. The scratch
volume category for the production site is 0012 andDR site’s scratch volume category is 0022. Before a DR
test is started, several DR system updates must be in place to protect the production scratch volumes from
being allocated during the test.
Assuming Selective Write Protect is enabled, which of the following is one step that must be taken?

A.
Update the DR TCDB volume entries to change the production volumes from 0012 to 0022

B.
Update the DR system’s DEVSUPxx parmlib member to use a unique scratch volume category

C.
Disconnect the grid link connections to ensure production volumes are not updated in the remote cluster
during the DR test

D.
Run the Return To Scratch process from the DR system to ensure the production and DR system volumes
are in sync and protected during a DR test
