rm showrmcanrollback
Function
The rm showrmcanrollback command is used to query whether remote replication supports a version rollback.
Usage Guidelines
This command is used to query whether remote replication supports a C version rollback. If a version rollback is not supported, the LUN with the minimum ID and 3DC configurations is
returned. To roll back the C version, you must delete at least a remote replication from the LUN.You must run this command for several commands to delete all the 3DC configurations before the rollback.
Example
l Query whether remote replication supports a version rollback (a version rollback is supported). 2 Query whether remote replication supports a version rollback (LUN 19 has 3DC configurations, so a version rollback is not supported).
admin:/diagnose>rm showrmcanrollback RM do not have 3DC configuration, can rollback. admin:/diagnose>rm showrmcanrollback RM_3DC: [Configed], (LUN id 19). RM have 3DC configuration, can not rollback. Please delete the 3DC configuration and retry.
