A Primary RLINK enters the fail state when the corresponding Secondary RLINK enters the FAIL state for any reason. This happens if there is an unrecoverable I/O error on one of the Secondary data volumes.
There are two ways for a Secondary RLINK to fail. One is if it encounters an I/O error that cannot be corrected. This is less likely to happen if the data volumes have been configured in a redundant fashion.
The second way for a Secondary RLINK to fail is if you enter the vxrlink -w pause command on the Secondary. Use this command carefully because the data volumes on the Secondary become writable. The command must be used if a data volume must be restored from backup.
# vxrlink -g diskgroup -c checkpoint_name restore rlink_name
This will return both the Primary and Secondary RLINKs to the ACTIVE state.
If the Secondary RLINK cannot be restored, or if it is no longer needed, then vxrlink det can be used on either the Primary or the Secondary to detach the Primary RLINK and make it STALE.
