B.
pairresync -g TC_db01 -swapp
C.
pairresync -g TC_db01 -swaps
D.
horctakeover -g TC_db01 -swapp

Several CCI device group names are used. The primary volumes are defined in horcm0.conf and the secondary volumes are defined in horcm1.conf. Which command would be used in a script to list all of the ShadowImage CCI device group names prior to executing the Pairresync command?
A. raidqry -g
B. raidscan -g
C. pairdisplay -g
D. cat /etc/horcm0.conf | grep group
Which two statements describe the characteristics of asynchronous replication? (Choose two.)
A. It provides a mechanism for copying data across any distance.
B. An incomplete operation is rolled back at both locations, guaranteeing that the remote copy is always an exact image of the primary.
C. After a successful write of data to the primary storage system, the application continues processing without waiting for an acknowledgement of a successful write at the secondary storage.
D. After a disruption, business operations can resume immediately at the remote site, starting from the exact point the primary site stopped. Only I/Os that were in-flight at the instant of disruption will be lost.
