2. Recover the Remote Copy groups from the synchronous storage system S347.

• The recover operation initiates reverse replication and synchronizes the changes from

the backup system to the primary system for the Remote Copy groups. Once executed,

the role of the Remote Copy groups on the source system becomes Secondary-Rev.

Any LUNs associated with volumes in the groups become non-writable on the source

system. The recover operation can be executed only on groups that have successfully

completed the failover operation.

• In this example, the recover operation will replicate and synchronize the delta changes

from the synchronous storage system S347 to the local storage system S256. The LUNs

used by the database ASM11GR2 from the synchronous storage system S347 become

non-writable.

a. After shutting down the ASM11GR2 database from the backup server panther and

bringing down all related ASM diskgroups, issue the following commands to recover the

Remote Copy groups from S356:

# setrcopygroup recover -f -t S256 linux_asm11gr2_data.r256

# setrcopygroup recover -f -t S256 linux_asm11gr2_arch.r256

# setrcopygroup recover -f -t S256 linux_asm11gr2_redo.r256

b. Once the recover operation completes, issue the showrcopy command on the synchronous

storage system S347 and local storage system S256 to display the following:
