Pausing and resuming replication to a Secondary

Pausing an RLINK prevents new and already-queued updates from reaching the Secondary from the Primary, and the Primary and Secondary do not communicate.

The vradmin pauserep command does not provide a way to pause a Secondary RLINK. To do this, use the vxrlink command on the Secondary host. The vradmin resumerep command resumes both types of pauses on the selected RLINKs.

  Note   If the latency protection is set to override, read Primary and Secondary disconnected.

 To pause and resume replication to a Secondary

To pause replication to a specific Secondary in an RDS, specify the Secondary hostname. For an RDS with a single Secondary, you do not have to specify the Secondary hostname.

On any host in the RDS:

1. Pause replication.

   # vradmin -g diskgroup pauserep local_rvgname [sec_hostname]

   where local_rvgname is the name of the RVG on the host where the command is issued, and sec_hostname is the name of the host to which replication is being paused.

2. On the Primary, issue the vxprint command to check that the state of the RLINK is pause.

   # vxprint rlink_name

3. Resume replication to the Secondary.

   # vradmin -g diskgroup resumerep local_rvgname \

[sec_hostname]

where local_rvgname is the name of the RVG on the host where the command is issued, and sec_hostname is the name of the host to which replication is being resumed.
