Set Failsafe at the Initiator Site (optional)
When failsafe is set, the remote copy set must contain one initiator member and one target
member. If the remote copy set loses the target member while failsafe is set, no further I/O
will be allowed to the initiator member, and an error will be returned to the host. This is
known as a failsafe locked condition and prevents the system from writing data that is not
protected from a disaster by a copy at the target site.
If you choose to set failsafe, enter the following command:
SET RemoteCopySetName ERROR_MODE=FAILSAFE
Example: SET RMTO ERROR_MODE=FAILSAFE
NOTE: When you set failsafe, all remote copy sets must be in a normal or normalizing state. If
remote copy sets are copying when you set failsafe, your command will be rejected until the
remote copy sets return to normal mode.
To remove the failsafe lock from a remote copy set and resume normal operation, use the
following CLI command:
SET RemoteCopySetName ERROR_MODE=NORMAL
Example: SET RMTO ERROR_MODE=NORMAL
This can also be used for remote copy sets where a DT-safe condition is not required.
NOTE: If the error mode is set to normal and there is no target member, the remote copy set is
no longer considered DT-safe.
